Without a doubt, we are living in a new era of large data-driven corporations. Gathering rich data about people and businesses has been a huge task over the years.

Proxycurl has made it easier to build and scale data-driven applications on people and businesses without having to worry about scaling a web scraping and data-science team.

## What is LinkDB?

## How to do a Simple Sample Search Queries on LinkDB

 LinkDB  requires a basic understanding of SQL, [JSON query functions and operators](https://www.postgresql.org/docs/current/functions-json.html), and [SQL/JSON path](https://www.postgresql.org/docs/current/functions-json.html#FUNCTIONS-SQLJSON-PATH) expressions. Let us begin with a  simple example.


    SELECT
      id,
      user_data->>'first_name' AS first_name, 
      user_data->>'last_name' AS last_name
      FROM profile
      LIMIT 10;


**Find Me All computer scientist  In California**

To find all the computer scientists in the database, you would write:


    SELECT
        id,
        user_data->>'first_name' AS first_name, 
        user_data->>'last_name' AS last_name,
        json_path_query_first(user_data, '$.experiences[*] ? (@.ends_at == null && @.title == "computer scientist" && @.location_California").title') AS title
    FROM profile
    WHERE to_tsvector('simple', used_data) @@ plainto_tsquery('simple', 'computer scientist')
      AND user_data @> '{"experiences": [{"ends_at": null, "title": "computer scientist", "location_California"}]}';
                            

The query above employs text search and JSON path syntax. Making use of a more SQL-like pattern.


**Find Me All Google  Employees**

To retrieve all employees of Google, you write the following SQL query:


    SELECT
        id,
        user_data->>'first_name' AS first_name,
        u_data->'last_name' AS last_name,
        json_path_query_first(user_data, '$.experiences[*] ? (@.ends_at == null && @.company_linkedin_profile_url == "https://www.linkedin.com/company/googl/").title') AS title
    FROM profile
    WHERE to_tsvector('simple', user_data) @@ plainto_tsquery('simple', 'https://www.linkedin.com/company/google/')
      AND user_data @> '{"experiences": [{"ends_at": null, "company_linkedin_profile_url": "https://www.linkedin.com/company/google/"}]}'

Proxycurl API is a set of tools designed to act as plumbing in your application for both fresh and processed data. We act as a fully managed layer between your application and raw data, allowing you to focus on building the application rather than scraping and processing data at scale.
You can use Proxycurl API to


- Search for people -
-  Search for businesses - 
- E-people's profiles - 
- Enrich company profiles
- Look up contact information for individuals and businesses.
- Determine whether an email address is disposable.


 If you want to experiment with the dataset in your local development environment, we've provided some sample data [here](https://nubela.co/blog/sample-data-for-linkdb/). Load the sample dataset into a relational database and use the sample queries above for inspiration.


## How We Keep LinkDB up to Date

Each time a real-time API is made to scrape a Linkedin profile, we update the dataset with the results of the API call. This means you wouldn't have to worry about stale data because this method keeps data on LinkDB constantly updated to the count of (up to) millions of profiles a day.


## Pricing

Our prices are typically in the five-digit range per data segment. We do not share price quotes to avoid a pricing war.

Instead, we provide a general price range, and I will direct you to test the finer points of our product, such as data quality or API standards.

And once you are certain that our product is right for you and that our price point is within your budget, we will begin the negotiation process.
