Look up a company

Turns a company name into up to five LinkedIn company pages whose name matches what you typed. It does not return similar companies or competitors. Use the linkedin_url as signal.company.linkedin_url on a LinkedIn engagement search, or as a company on POST /leads and POST /company/enrich.

Authentication

Send Authorization: Bearer gtk_…. Create the key under API Access → API Keys. A missing, invalid or revoked key is 401, including while this API is closed. A valid key while the API is closed for your organization answers 404, the same body as an unknown path. Every response includes FounderMCP-Api-Version and FounderMCP-Request-Id.
