How much does the Y Combinator Search Companies API cost?

What parameters does the Y Combinator Search Companies API accept?

What does the Y Combinator Search Companies API return?

A JSON result. This endpoint runs asynchronously, so the response tells you how to fetch the finished result.

Do I need a Y Combinator developer account or API key?

No. Y Combinator Search Companies runs through SandBase, so one SandBase API key covers this endpoint and every other API and model in the catalog. You do not need to apply for Y Combinator API access separately.
