Top 8 Blockchain APIs for Developers
Published: 2023-01-07 03:08:00

Developers are always looking for new ways to make their applications more secure and efficient. Blockchain APIs are one way to do this. A blockchain API is an application programming interface that allows developers to interact with a blockchain. By using a blockchain API, developers can access the data and functionality of a blockchain without having to build their own blockchain platform. This can save time and resources, as well as provide a more secure environment for development. In this post, we will explore the best blockchain APIs for developers. We will look at the features and benefits of each blockchain API, as well as how they can be used to create more secure and efficient decentralized applications.

## What Is Blockchain?
A blockchain is a digital ledger of all cryptocurrency transactions. It is constantly growing as “completed” blocks are added to it with a new set of recordings. Each block contains a cryptographic hash of the previous block, a timestamp, and transaction data. Bitcoin nodes use the block chain to differentiate legitimate Bitcoin transactions from attempts to re-spend coins that have already been spent elsewhere.

The API allows the blockchain developer to interact with the blockchain in a variety of ways. For example, they can create wallets for users, send and receive payments, and check balances. The API also enables developers to monitor markets and trends, as well as create applications that can be used to track prices or manage investments.

The most popular blockchain is the one that powers Bitcoin, but there are many other types of blockchains being developed for a variety of purposes. Some of these include Ethereum, Litecoin, and Monero.

## What Are the Benefits of Using Blockchain APIs?
Blockchain APIs offer a number of benefits for developers. They can help to streamline the process of developing applications and make it easier to integrate with other systems. In addition, Blockchain APIs can provide access to data that is stored on the blockchain, making it easier for developers to create applications that make use of this crypto data.

Blockchain APIs can also help to reduce the costs associated with developing applications. By making it easier to access data stored on the blockchain, developers can avoid the need to build their own infrastructure to support their decentralized application. This can lead to significant savings in both time and money.

In addition, Blockchain APIs can provide developers with a way to monetize their applications. By charging for access to data or functionality provided by an API, developers can generate revenue from their applications. This can help to offset the costs of developing and maintaining a decentralized application.

Finally, Blockchain APIs can help to create a more open and accessible ecosystem for applications. By making it easier for developers to access data and functionality provided by other applications, Blockchain APIs can help to create an environment where applications can interoperate with each other. This can lead to new and innovative app development being created that would not be possible without the use of APIs.

Performance: Blockchain APIs vary in performance and capacity, so it’s important to pick one that meets the needs of your application. A few transactions per second may be enough if you just need to encrypt a couple of documents, but apps with thousands of transactions per second will require subsystems called microservices. These will allow for handling high loads and continued responsiveness when processing user requests.

Compatibility: You’ll want to make sure the API you choose can support the coins you need.

## How To Use Blockchain APIs
If you’re a blockchain developer looking to get started with blockchain technology, one of the first things you’ll need is a blockchain API. This will allow you to interact with the blockchain and build your blockchain application on top of it.

There are many different blockchain APIs available, so it’s important to choose one that’s right for your needs. Some factors to consider include the programming language you’re using, the features you need, and the level of development tools offered.

Once you’ve chosen a blockchain API, you’ll need to register for an account and get an API key. Then, you can start building your app development.

Be sure to test your application thoroughly before deploying it. And, always monitor the blockchain for changes that could affect your application. Tools such as Moesif can help leverage a browser SDK to access API call data from the client side. From there, we can generate debugging and monitoring reports to ensure your site’s running smoothly. If something does go wrong, we’ll alert you immediately so that it doesn’t have time to expand into a larger problem.

**Support and Monitoring with Moesif**
Moesif has unique features that allow you to associate each event that occurs in your app with a user and/or company. This gives a more nuanced understanding of the developer experience and how APIs are being used by each individual. A perfect example of this is Funnels and Retention.

[Funnels](https://www.moesif.com/docs/user-analytics/conversion-funnel-analysis/?utm_campaign=DevTo&utm_source=placed-article&utm_medium=paid&utm_content=top-8-blockchain) are a step-by-step breakdown of a flow within your app. For example, you might be optimizing your sign-up process and looking for ways to speed it up. This analysis provides you with insights and how long it takes users to make their way through the steps and what percentage of customers complete them. This is important, as it helps establish a baseline you can use as you try to improve conversions and API usage.

A [retention](https://www.moesif.com/docs/user-analytics/cohort-retention-analysis/?utm_campaign=DevTo&utm_source=placed-article&utm_medium=paid&utm_content=top-8-blockchain) analysis can help determine when customers are quitting or becoming inactive with your product and APIs. This can help to improve retention and allow you to know when there is a problem with your developer experience. This will enable you to establish baselines to correlate improvements or deterioration of your developer experience with the retention of users.

Another way to track your API usage is to use alerts to let you now when users are having difficulties or to let you know about anomalies in traffic. For example, an alert might be used to let a customer success team know about issues that users are experiencing so they can reach out and help. Alerts also allow product teams to learn from feedback on issues in the short-term and make improvements in the future. Alerts are made up of two types: Static and Dynamic.

Static alerts can be set as a specific threshold, like having more than 3 401 - Unauthorized errors in an hour. Dynamic alerts allow you to set a threshold such as noticing when a user is experiencing a surge in 401 errors compared to their average amount. It allows you to monitor trends or spikes without putting a specific number in for the threshold.

Both forms of alerts can improve the user experience within your product, especially if it’s high quality and supportive from its team members. For more info on how to create an alert in Moesif, check out our docs.

Moesif allows you to set up automated email flows based on events your users are experiencing. This is done through creating [behavioral emails.](https://www.moesif.com/docs/behavioral-emails/?utm_campaign=DevTo&utm_source=placed-article&utm_medium=paid&utm_content=top-8-blockchain) For instance, if a user has a high number of 401 - Unauthorized responses then you may want to send them an email with suggestions on how to fix the issue or a guide. This takes the pressure off the support team and also makes it possible for instant and proactive action to be taken.

## Customer Success using Moesif
Leading customer success for API-first or developer-focused businesses is much different from traditional enterprise software, The best API products are built in a way that make them easy to use and hands-off, meaning customers don’t have to log in to the platform once it’s implemented.

When customer success works with API-first businesses, they should be prepared for two different experiences with their customers. The first experience is when the customer signs up and logs into your portal. Second, there is the customer’s experience when integrating with and interaction with your API platform. Both are considered to be part of the onboarding experience, and metrics should be recorded for each one. What’s more, it is the API that has the potential to offer long-term value. Customers who sign up but never fully integrate with or use that platform can churn quickly (if they’re paying already).

In Moesif, every API call can be attributed to a user and/or company. Moesif creates a profile for each of these companies and users which allows customer success teams to have a CRM-style view of the customers attributes.

Customer success teams can also easily track customer interaction with the platform and keep an eye on key customer health metrics. These metrics will show under the user or companies profile dashboard. Having the ability to see customer metrics in a visual dashboard which shows customer usage, including errors and integration problems that may be occurring.
