Email to LinkedIn

The Email to LinkedIn API resolves an email address to the highest-confidence LinkedIn profile URL when multiple candidates exist.

It scores all matching profiles and returns the single best full LinkedIn URL. Use this when match quality matters, for example before personalising outreach, triggering enrichment workflows, or appending LinkedIn data to a contact record.

Use this endpoint to:

Attach the correct LinkedIn profile to an email-only contact
Personalise outreach with accurate LinkedIn context
Trigger downstream enrichment workflows from an email address

Fair Use Policy: This API is subject to our Fair Use Policy for Enrichment.

Outcomes: A lookup that finds nothing is not an error. It returns HTTP 200 with status: "not_found", empty or null results, and the usual metadata — and costs no tokens, though it still counts as one request against your Fair Use requests limit. Read status, not the HTTP code, to tell a hit from a miss. The API’s only 404 is an unknown or retired tool name.
