Lookup Companies

Resolve companies to their canonical OpenFunnel record(s) by any subset of name / domain / linkedin_url. Batch up to 100 per call. No credits are charged.

No API key yet? Sign up via Agent Auth to get your X-API-Key - the only required header for this endpoint.

Each item may carry any combination of identifiers:

• domain → exact match on any of the company’s domains. Returns all matching records.
• linkedin_url → exact match on the company’s LinkedIn slug (parsed from the URL).
• name → fuzzy match; returns up to 10 ranked candidates with a relevance score.

If an item includes a domain or linkedin_url, it is resolved by that exact identifier and the name is ignored - the fuzzy name path runs only when name is the sole identifier. Matches are deduped by company_id (precedence: linkedin > domain > name). A returned company_id can be passed straight back into Search Lookalikes as a seed. Unknown inputs return status: "not_found" with an empty matches array.
