// CONTACT VERIFICATION

Live contact verification API

Real-time check that a contact still exists, is in the same role, and is reachable. The freshness layer that keeps your data from rotting between enrichment runs.

✓ Live check: still in role, same company, same title
✓ Returns a freshness score + last-seen timestamp
✓ Use before every outbound action your agent takes
✓ Pair with Contact data for end-to-end freshness

Before your sequencing agent fires, run every contact through verification. Skip the dead ones, save deliverability.

CRM rot detection

Run verification across your CRM weekly. Surface every contact that needs an update or removal.

Job-change watcher

Subscribe to a contact and get a webhook when they change role — your agent acts on the signal.
