     DETAILED DESCRIPTION OF PREFERRED EMBODIMENTS 
     The following detailed description of example implementations refers to the accompanying drawings. The same reference numbers in different drawings may identify the same or similar elements. 
     In some instances, an application executing on a user equipment (UE) may communicate with a service (e.g., a web service) according to an API. For example, the application may transmit a request (e.g., an API request) to the service, requesting the service to perform a particular action. In some cases, the particular action may instruct the service to retrieve, add, modify, delete, and/or the like, data in a database associated with the service. The data involved may be sensitive, intended only for a particular user, critical to a system&#39;s functionality, and/or the like. Thus, retrieval, or manipulation, of the data may expose sensitive data, impair a system&#39;s functionality, and/or the like. However, current techniques do not inspect a request to a service, prior to the request reaching the service, in order to determine whether an action instructed by the request is a permissible action for a user making the request. Thus, current techniques may allow invalid requests to be received and processed by the service, thereby exposing the service and associated data to security threats, as well as consuming computing resources of the service that could otherwise be used for processing valid requests. 
     According to some implementations described herein, a verification platform may provide inspection of a request (e.g., an API request), prior to the request being processed by a service (e.g., a web service), to determine whether an action instructed by the request is a permissible action. For example, the verification platform may receive, from a UE, authentication data that includes user information associated with a user of the UE and determine whether the user is authorized to make requests to a service (e.g., according to an API). Based on the authentication data, the verification platform may grant access to the UE to make requests to the service, and thereafter receive, from the UE, a request that is intended for the service. The request may relate to an action that is to be performed by the service. Prior to providing the request to the service, the verification platform may determine whether the user has permission to request the action. If the user is authorized to request the action, the verification platform may provide the request to the service (e.g., to permit the service to perform the action of the request), receive, from the service, a response (e.g., an API response) to the request, and provide the response to the UE. 
     In this way, the verification platform provides inspection of the contents of the API request prior to the request reaching the service. Accordingly, API requests that are improperly formed, that are unauthorized, and/or the like may be discarded by the verification platform without being forwarded to the service. As a result, the verification platform facilitates a reduction in, or an elimination of, API requests that contain errors, that request unauthorized actions, that contain malicious code, and/or the like that are processed by the service. By reducing the service&#39;s processing of invalid requests, the verification platform improves the efficiency of the service, and conserves computing resources that may otherwise be wasted processing invalid requests. Moreover, by reducing the web service&#39;s processing of invalid requests, the verification platform improves the security and stability of the service and associated data. 
       FIGS. 1A-1C  are diagrams of one or more example implementations  100  described herein. As shown in  FIGS. 1A-1C , example implementation(s)  100  may include a UE  101 , a verification platform  102 , and a service  103  (depicted in  FIG. 1C ). 
     UE  101  may be a mobile device, a smart phone, an internet of things (IoT) device, a wearable communications device, and/or the like. Additionally, UE  101  may be a smart device, such as an Internet-enabled parking meter, an Internet-enabled electronic billboard, an Internet-enabled video camera, an Internet-enabled tracking device, and/or the like. UE  101  may communicate with a data network (e.g., the Internet) via a network, such as a cellular network (e.g., a 5G network). In some cases, UE  101  may be assigned a static Internet Protocol (IP) address when UE  101  is configured with the network. Moreover, UE  101  may be associated with a user. For example, the user may be an entity (e.g., an enterprise) that has access to functions of a core network of the network in order to provision, manage, and/or modify a firewall for one or more UEs associated with the user. 
     Verification platform  102  may be a computing device, a server, a cloud computing device, and/or the like that processes authentication data, processes requests (e.g., API requests), processes responses (e.g., API responses) to the requests, and/or the like. The verification platform  102  may be associated with a network (e.g., the core network of the network). For example, the verification platform may be a proxy server (e.g., a reverse proxy server, a gateway server, and/or the like) that acts as an intermediary between UE  101  and service  103  (e.g., a web service). Accordingly, requests (e.g., API requests) transmitted by UE  101  and intended for service  103  may be processed by verification platform  102  before being forwarded to service  103 . 
     Service  103  may be a service associated with an API. For example, service  103  may be a web service (e.g., a web service provided by the network), a core network service, and/or the like, that is exposed according to an API. Service  103  may be implemented by a server, such as a server associated with the core network of the network. Service  103  may permit UE  101  to access and/or modify data associated with the network (e.g., associated with the core network). For example, service  103  may permit UE  101  to provision, manage, and/or modify a firewall for one or more UE associated with the user. 
     Service  103  may be a web service that permits access to, and/or modification of, data maintained in the core network via one or more API endpoints. The web service may be implemented according to simple object access protocol (SOAP), representational state transfer (REST), and/or the like. Additionally, or alternatively, service  103  may be a service capability exposure function (SCEF), a network exposure function (NEF), and/or the like of the core network. The SCEF or NEF may permit UE  101  to access and/or modify network capabilities, for example, to provision a firewall, associate or disassociate one or more UEs with the firewall, modify settings for the firewall, and/or the like. 
     While the description to follow will be described in terms of an example of a request intended for a service of a core network, the description is not limited to this particular example. Implementations described herein also apply to any type of request to access and/or modify information that is made from a first device to a second device (e.g., a web server), such as via hypertext transfer protocol (HTTP), via an API, and/or the like. 
     As shown in  FIG. 1A , and by reference number  105 , verification platform  102  may obtain an authentication request from UE  101 . The authentication request may include authentication data. The authentication data may include user information associated with UE  101  and/or the user. For example, the user information may identify a name of the user (e.g., an enterprise name), an identifier of the user (e.g., an alphanumeric identifier), an identifier of UE  101  (e.g., an alphanumeric identifier, such as an Internet Protocol (IP) address, a Media Access Control (MAC) address, and/or the like). 
     The authentication data may be a digital certificate (e.g., a public key certificate, such as an X.509 certificate). For example, verification platform  102  may provide a user interface that includes an input element that permits the user to transmit (e.g., via a secure connection) the digital certificate to verification platform  102 . In some implementations, the authentication request may comprise a connection request of UE  101  to connect to service  103  (e.g., via a uniform resource locator (URL) associated with a particular endpoint of service  103 ), and UE  101  may provide a digital certificate as part of the connection request. 
     The digital certificate may identify the user information. For example, the digital certificate may include a subject distinguished name field that identifies a name of the user (e.g., an enterprise) to which the digital certificate was issued. 
     Additionally, or alternatively, the authentication data may include a username and password combination, a token, and/or the like. In such a case the username, the token, and/or the like, may be associated with an account of the user that contains user information (e.g., an identifier of the user). In some implementations, the authentication data may include a first authentication factor and a second authentication factor. For example, the first authentication factor may be the digital certificate and the second authentication factor may be a username and password combination, a token (e.g., a token that is messaged to UE  101  after successful authentication of the first authentication factor), and/or the like. 
     As shown by reference number  110 , verification platform  102  may authenticate UE  101  to perform requests (e.g., based on the authentication data). For example, verification platform  102  may determine whether the user is authorized to make requests (e.g., API requests) to service  103 . Verification platform  102  may make this determination based on the authentication data obtained from UE  101 . 
     For example, verification platform  102  may inspect the digital certificate obtained from UE  101  (e.g., by terminating a secure connection with UE  101 ) and obtain user information contained by the digital certificate (e.g., a value contained in a subject distinguished name field of the digital certificate). Verification platform  102  may determine, based on the user information, whether the user is authorized to make requests to service  103  (e.g., based on whether the user is included in a record of authorized users of service  103 ). In some cases, verification platform  102  may determine, based on the user information, whether the user is authorized to make requests to a particular endpoint of service  103 . To do so, verification platform  102  may maintain, or have access to, a data structure (e.g., a database, a linked list, a table, and/or the like) that contains information relating to authorized users of service  103  and/or authorized users of particular endpoints of service  103 . 
     In some implementations, verification platform  102  may determine whether UE  101  is authorized to make requests (e.g., API requests) to service  103 . For example, when the user information includes an identifier of UE  101  (e.g., an IP address), verification platform  102  may determine whether UE  101  is authorized to make requests based on the identifier of UE  101 . As an example, verification platform  102  may determine whether an IP address of UE  101  corresponds to an IP address assigned to the user. 
     As shown by reference number  115 , verification platform  102  may provide an authentication response to UE  101 . For example, verification platform  102  may determine that the user information corresponds to an authorized user of service  103 , and may provide an authentication response to UE  101  indicating that UE  101  is authorized to make requests to service  103 . In some cases, the authentication response may comprise verification platform  102 &#39;s acceptance of a connection request of UE  101  to connect to service  103 . Based on determining that the user is authorized to make requests to service  103 , verification platform  102  may grant access to UE  101  to make requests to service  103 . 
     In some cases, verification platform  102  may determine that the user information does not correspond to an authorized user of service  103 , and may provide an authentication response to UE  101  indicating that UE  101  is not authorized to make requests to service  103 . In such cases, verification platform  102  may determine to deny access to UE  101  to make requests to service  103 . For example, UE  101  may be denied access to an interface through which requests may be made. As another example, verification platform  102  may reject any requests made by UE  101  after determining to deny access to UE  101 . 
     As shown in  FIG. 1B , and by reference number  120 , verification platform  102  may obtain a request (e.g., an API request) transmitted by UE  101 . For example, verification platform  102  may obtain a request transmitted by UE  101  via a secure connection (e.g., a secure socket layers (SSL) connection, a transport layer security (TLS) connection, and/or the like) established between UE  101  and verification platform  102 . The request may instruct one or more actions that are to be performed by service  103 . For example, the request may instruct service  103  to provide information associated with an account of the user (e.g., configuration settings associated with the account of the user), modify information associated with the account of the user (e.g., associate or disassociate one or more UEs with the account of the user), provision a firewall for the account of the user, configure a firewall rule for the account of the user, and/or the like. 
     As shown by reference number  125 , verification platform  102  may determine whether the user has permission to instruct the one or more actions of the request. In such a case, verification platform  102  may inspect the request (e.g., a content (i.e., payload) of the request). If the request was transmitted by UE  101  via a secure connection between UE  101  and verification platform  102 , verification platform  102  may decrypt the request in order to inspect the request. Verification platform  102  may inspect the request to determine a type of an action that is instructed by the request. The type of the action may be a query type, an add type, a delete type, an update type, a provisioning type, a configuration type, and/or the like. 
     Verification platform  102  may determine whether the type of the action instructed is a permissible type of action for the user to instruct. Thus, the user may be associated with one or more rules (e.g., a rule set) that define permissible types of actions that may be instructed by the user. For example, a first user may be associated with a first rule set indicating that the first user may instruct service  103  to retrieve information (e.g., a query type of action), add information (e.g., an add type of action), and delete information (e.g., a delete type of action), while a second user may be associated with a second rule indicating that the second user only may instruct service  103  to retrieve information. Accordingly, verification platform  102  may maintain, or have access to, a data structure (e.g., a database, a linked list, a table, and/or the like) that contains information relating to respective rule sets for each user that is authorized to make requests to service  103 . 
     In some implementations, verification platform  102  may determine whether the type of the action instructed is a permissible type of action for UE  101  to instruct. Thus, UE  101  may also be associated with a rule set that defines permissible types of actions that may be instructed by UE  101 , and the data structure may also contain information relating to respective rule sets for each UE that is authorized to make requests to service  103 . 
     Verification platform  102  may determine that the user has permission to instruct a particular action when the type of the action is a permissible type of action that may be instructed by the user (e.g., the type of the action is included in a rule set associated with the user). Similarly, verification platform  102  may determine that the user does not have permission to instruct a particular action when the type of the action is not a permissible type of action that may be instructed by the user (e.g., the type of the action is not included in a rule set associated with the user). In this way, verification platform  102  may facilitate role-based access control to service  103 , thereby permitting different users to be associated with different levels of access that account for different risk levels, different expertise levels, and/or the like, among the different users. 
     Verification platform  102  may also determine whether the user has permission to instruct the one or more actions of the request based on an account that would be affected by the one or more actions. For example, verification platform  102  may determine that the user does not have permission to instruct an action when the action would access or modify information of an account that is not associated with the user. 
     In some implementations, verification platform  102  may determine whether the request is in accordance with one or more operations, parameters, schema, and/or the like designated for the API. For example, verification platform  102  may determine whether the request is in accordance with a web services description language (WSDL) associated with service  103 . 
     As shown in  FIG. 1C , and by reference number  130 , verification platform  102  may forward the request to service  103 . That is, verification platform  102  may forward the request to service  103  based on determining that the user has permission to instruct the one or more actions of the request. In such a case, verification platform  102  may establish a secure connection with service  103 , such as by exchanging digital certificates with service  103 , and may provide the request to service  103  via the secure connection. 
     In some cases, verification platform  102  may discard the request, without providing the request to service  103 , based on determining that the user does not have permission to instruct the one or more actions of the request. Moreover, verification platform  102  may discard the request, without providing the request to service  103 , based on determining that the request is not well-formed (e.g., the request is not in accordance with one or more operations, parameters, schema, and/or the like designated for the API). In some implementations, verification platform  102  may discard the request if UE  101  and/or the user has reached a limit on a quantity of requests that may be made, if the request was made outside of a particular time window during which requests must be made, and/or the like. In this way, verification platform  102  selectively provides requests to service  103 , thereby conserving computing resources that may otherwise be wasted by service  103  when processing requests that are invalid. 
     As shown by reference number  135 , service  103  may process the request provided by verification platform  102 . If the request was provided to service  103  via a secure connection between verification platform  102  and service  103 , service  103  may decrypt the request in order to process the request. Service  103  may process the request according to the one or more actions instructed by the request. 
     In some cases, service  103  may perform the one or more actions and generate a response relating to the performance of the one or more actions. For example, service  103  may retrieve information, as instructed by the request, and generate a response that includes the retrieved information. As another example, service  103  may add information to an account, as instructed by the request, and generate a response indicating that the information was added to the account. In other cases, service  103  may deny the request. For example, service  103  may deny the request if UE  101  and/or the user has reached a limit on a quantity of requests that may be made, if the request was made outside of a particular time window during which requests must be made, and/or the like. In such cases, service  103  may generate a response indicating that one or more actions of the request were not performed. Service  103  may provide the response (e.g., an API response) to verification platform  102  (e.g., via the secure connection between service  103  and verification platform  102 ). 
     As shown by reference number  140 , verification platform  102  may obtain the response (e.g., the API response) from service  103 . For example, verification platform  102  may obtain the response via the secure connection between service  103  and verification platform  102 . Accordingly, verification platform  102  may decrypt the response to identify a content of the response. Moreover, verification platform  102  may inspect and/or manipulate the content of the response. For example, verification platform  102  may inspect the content to determine whether the content of the response is well-formed, may convert the content to a particular format (e.g., JavaScript object notation (JSON), extensible markup language (XML), and/or the like) desired by UE  101 , and/or the like. 
     As shown by reference number  145 , verification platform  102  may provide the response to UE  101 . For example, verification platform  102  may provide the response to UE  101  via the secure connection between UE  101  and verification platform  102 . In some implementations, verification platform  102  may log information relating to the request (e.g., the content of the request, whether the request was discarded, why the request was discarded) and/or the response (e.g., the content of the response, whether the response was well-formed or manipulated, and/or the like). 
     In this way, verification platform  102  facilitates communication between UE  101  and service  103  with improved security and stability. By inspecting the content of requests transmitted by UE  101 , verification platform  102  determines whether the requests are valid before the requests are provided to service  103 . Accordingly, verification platform  102  ensures that requests provided to service  103  are valid and unlikely to cause a security concern or originate from a malicious source. In this way, verification platform  102  permits a network to expose various core network functionality to users with improved security, while reducing or eliminating the possibility that destabilizing changes will be made to the functionality.

Server device  230  may perform one or more functions described herein as being performed by service  103 . 
     Network  240  includes one or more wired and/or wireless networks.

       FIG. 3  is a diagram of example components of a device  300 . Device  300  may correspond UE  210 , verification platform  220 , and/or server device  230 . In some implementations UE  210 , verification platform  220 , and/or server device  230  may include one or more devices  300  and/or one or more components of device  300 . As shown in  FIG. 3 , device  300  may include a bus  310 , a processor  320 , a memory  330 , a storage component  340 , an input component  350 , an output component  360 , and a communication interface  370 . 
     Bus  310  includes a component that permits communication among multiple components of device  300 . Processor  320  is implemented in hardware, firmware, and/or a combination of hardware and software. Processor  320  is a central processing unit (CPU), a graphics processing unit (GPU), an accelerated processing unit (APU), a microprocessor, a microcontroller, a digital signal processor (DSP), a field-programmable gate array (FPGA), an application-specific integrated circuit (ASIC), or another type of processing component.

Additionally, or alternatively, input component  350  may include a component for determining location (e.g., a global positioning system (GPS) component) and/or a sensor (e.g., an accelerometer, a gyroscope, an actuator, another type of positional or environmental sensor, and/or the like). Output component  360  includes a component that provides output information from device  300  (via, e.g., a display, a speaker, a haptic feedback component, an audio or visual indicator, and/or the like). 
     Communication interface  370  includes a transceiver-like component (e.g., a transceiver, a separate receiver, a separate transmitter, and/or the like) that enables device  300  to communicate with other devices, such as via a wired connection, a wireless connection, or a combination of wired and wireless connections. Communication interface  370  may permit device  300  to receive information from another device and/or provide information to another device. For example, communication interface  370  may include an Ethernet interface, an optical interface, a coaxial interface, an infrared interface, a radio frequency (RF) interface, a universal serial bus (USB) interface, a wireless local area network interface, a cellular network interface, and/or the like. 
     Device  300  may perform one or more processes described herein. Device  300  may perform these processes based on processor  320  executing software instructions stored by a non-transitory computer-readable medium, such as memory  330  and/or storage component  340 . As used herein, the term “computer-readable medium” refers to a non-transitory memory device. A memory device includes memory space within a single physical storage device or memory space spread across multiple physical storage devices. 
     Software instructions may be read into memory  330  and/or storage component  340  from another computer-readable medium or from another device via communication interface  370 . When executed, software instructions stored in memory  330  and/or storage component  340  may cause processor  320  to perform one or more processes described herein. Additionally, or alternatively, hardware circuitry may be used in place of or in combination with software instructions to perform one or more processes described herein. Thus, implementations described herein are not limited to any specific combination of hardware circuitry and software. 
     The quantity and arrangement of components shown in  FIG. 3  are provided as an example. In practice, device  300  may include additional components, fewer components, different components, or differently arranged components than those shown in  FIG. 3 . Additionally, or alternatively, a set of components (e.g., one or more components) of device  300  may perform one or more functions described as being performed by another set of components of device  300 . 
       FIG. 4  is a flow chart of an example process  400  for inspection of contents of a request. In some implementations, one or more process blocks of  FIG. 4  may be performed by a verification platform (e.g., verification platform  220 ). In some implementations, one or more process blocks of  FIG. 4  may be performed by another device or a group of devices separate from or including the verification platform, such as a UE (e.g., UE  210 ), a server device (e.g., server device  230 ), and/or the like. 
     As shown in  FIG. 4 , process  400  may include receiving, from a UE, a request that is intended for a service (block  410 ). For example, the verification platform (e.g., using processor  320 , memory  330 , storage component  340 , input component  350 , communication interface  370 , and/or the like) may receive a request that is intended for a service, as described above. The request may be received from the UE via a first secure connection. The service may be located on a server device that is accessible according to an API. For example, the service may be an SCEF or an NEF of a network. 
     The UE may be associated with a user and the request may relate to an action that is to be performed by the service. Thus, process  400  may include, prior to receiving the request, determining whether the user is authorized to make requests to the service. For example, process  400  may include receiving authentication data (e.g., a public key certificate) that includes user information associated with the user, and determining whether the user is authorized to make requests to the service based on the authentication data. Determining whether the user is authorized to make requests to the service may be further based on whether an address associated with the UE corresponds to an address assigned to the user. Moreover, process  400  may include granting access to make requests to the service (e.g., based on whether the user is authorized to make requests to the service). However, in some cases, determining whether the user is authorized to make requests to the service may include determining that the user is not authorized to make requests to the service and determining to deny access to the user to make requests to the service. 
     As further shown in  FIG. 4 , process  400  may include determining whether a type of an action instructed by the request is a permissible type of action (block  420 ). For example, the verification platform (e.g., using processor  320 , memory  330 , storage component  340 , and/or the like) may determine whether a type of an action instructed by the request is a permissible type of action, as described above. In other words, the verification platform may determine whether the user has permission to request the action. In some cases, determining whether the user has permission to request the action may include determining that the user does not have permission to request the action and discarding the request prior to providing the request to the service. 
     In some implementations, the request from the UE may be encrypted when received, and process  400  may include performing decryption of the request in order to determine whether the type of the action instructed by the request is the permissible type of action. Additionally, process  400  may include determining that the request is not formatted for processing by the service, and discarding the request prior to providing the request to the service. For example, process  400  may include determining, before determining whether the type of the action instructed by the request is the permissible type of action, whether the request is in accordance with a WSDL associated with the service. 
     As further shown in  FIG. 4 , process  400  may include providing, based on whether the type of the action instructed by the request is the permissible type of action, the request to the service (block  430 ). For example, the verification platform (e.g., using processor  320 , memory  330 , storage component  340 , output component  360 , communication interface  370 , and/or the like) may provide the request to the service, as described above. For example, the verification platform may be a reverse proxy server associated with the service. The request may be provided to the service via a second secure connection. 
     As further shown in  FIG. 4 , process  400  may include receiving, from the service, a response to the request (block  440 ). For example, the verification platform (e.g., using processor  320 , memory  330 , storage component  340 , input component  350 , communication interface  370 , and/or the like) may receive the response to the request, as described above. The response may be received from the service via the second secure connection. 
     As further shown in  FIG. 4 , process  400  may include providing, to the UE, the response (block  450 ). For example, the verification platform (e.g., using processor  320 , memory  330 , storage component  340 , output component  360 , communication interface  370 , and/or the like) may provide the response, as described above. The response may be provided to the UE via the first secure connection. 
     Although  FIG. 4  shows example blocks of process  400 , in some implementations, process  400  may include additional blocks, fewer blocks, different blocks, or differently arranged blocks than those depicted in  FIG. 4 . Additionally, or alternatively, two or more of the blocks of process  400  may be performed in parallel. 
     The foregoing disclosure provides illustration and description, but is not intended to be exhaustive or to limit the implementations to the precise form disclosed. Modifications and variations may be made in light of the above disclosure or may be acquired from practice of the implementations. 
     As used herein, the term “component” is intended to be broadly construed as hardware, firmware, or a combination of hardware and software. 
     Certain user interfaces have been described herein. A user interface may include a graphical user interface, a non-graphical user interface, a text-based user interface, and/or the like. A user interface may provide information for display. In some implementations, a user may interact with the information, such as by providing input via an input component of a device that provides the user interface for display. In some implementations, a user interface may be configurable by a device and/or a user (e.g., a user may change the size of the user interface, information provided via the user interface, a position of information provided via the user interface, and/or the like). Additionally, or alternatively, a user interface may be pre-configured to a standard configuration, a specific configuration based on a type of device on which the user interface is displayed, and/or a set of configurations based on capabilities and/or specifications associated with a device on which the user interface is displayed. 
     To the extent the aforementioned implementations collect, store, or employ personal information of individuals, it should be understood that such information shall be used in accordance with all applicable laws concerning protection of personal information. Additionally, the collection, storage, and use of such information can be subject to consent of the individual to such activity, for example, through well known “opt-in” or “opt-out” processes as can be appropriate for the situation and type of information. Storage and use of personal information can be in an appropriately secure manner reflective of the type of information, for example, through various encryption and anonymization techniques for particularly sensitive information. 
     It will be apparent that systems and/or methods described herein may be implemented in different forms of hardware, firmware, and/or a combination of hardware and software. The actual specialized control hardware or software code used to implement these systems and/or methods is not limiting of the implementations. Thus, the operation and behavior of the systems and/or methods are described herein without reference to specific software code—it being understood that software and hardware may be used to implement the systems and/or methods based on the description herein. 
     Even though particular combinations of features are recited in the claims and/or disclosed in the specification, these combinations are not intended to limit the disclosure of various implementations. In fact, many of these features may be combined in ways not specifically recited in the claims and/or disclosed in the specification. Although each dependent claim listed below may directly depend on only one claim, the disclosure of various implementations includes each dependent claim in combination with every other claim in the claim set. 
     No element, act, or instruction used herein should be construed as critical or essential unless explicitly described as such. Also, as used herein, the articles “a” and “an” are intended to include one or more items, and may be used interchangeably with “one or more.” Further, as used herein, the article “the” is intended to include one or more items referenced in connection with the article “the” and may be used interchangeably with “the one or more.” Furthermore, as used herein, the term “set” is intended to include one or more items (e.g., related items, unrelated items, a combination of related and unrelated items, and/or the like), and may be used interchangeably with “one or more.” Where only one item is intended, the phrase “only one” or similar language is used. Also, as used herein, the terms “has,” “have,” “having,” or the like are intended to be open-ended terms. Further, the phrase “based on” is intended to mean “based, at least in part, on” unless explicitly stated otherwise. Also, as used herein, the term “or” is intended to be inclusive when used in a series and may be used interchangeably with “and/or,” unless explicitly stated otherwise (e.g., if used in combination with “either” or “only one of”).
