​
How It Works

Describe who you’re looking for in plain English. The API translates your description into a SQL query and returns matching profiles. The generated SQL query is returned in the generated_query field of the response body so you can see exactly how your description was interpreted.

​
Example Queries

software engineers in Austin who worked at Meta
marketing directors at Fortune 500 companies in New York
nurses in California with 10+ years of experience
VP of Sales at SaaS companies with over 1000 employees
data scientists with Python skills in the Bay Area
For precise control over filtering, use Person Search with SQL syntax instead.
