How to do a Simple Sample Search Queries on LinkDB

LinkDB requires a basic understanding of SQL, JSON query functions and operators, and SQL/JSON path expressions. Let us begin with a simple example.

  user_data->>'first_name' AS first_name, 
  user_data->>'last_name' AS last_name
  FROM profile
  LIMIT 10;
Enter fullscreen mode Exit fullscreen mode

Find Me All computer scientist In California

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

    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"}]}';
Enter fullscreen mode Exit fullscreen mode

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:

    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 == "").title') AS title
FROM profile
WHERE to_tsvector('simple', user_data) @@ plainto_tsquery('simple', '')
  AND user_data @> '{"experiences": [{"ends_at": null, "company_linkedin_profile_url": ""}]}'
Enter fullscreen mode Exit fullscreen mode

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. 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.


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.
