Endpoints
Six endpoints. Full signal coverage.
Search, enrich, subscribe, and monitor — everything you need in a clean REST interface.

Returns contact-level signals (job changes, LinkedIn posts, milestones) and their employer's company signals in one call.
/v1/companies/{domain}/timeline
Company Timeline
Chronological view of all recent signals for a company. See what happened in the last 7, 30, or 90 days.
