What are the caveats?

Not a native Clay integration as of 2026-10-17 (checked against Clay's integrations catalog). Can be called through Clay's HTTP API column where an API exists. Related job data providers TheirStack, PredictLeads and Coresignal are in Clay; these direct endpoints are not. External observation: a posting shows intent to hire, not budget approval, and reposts can look like new roles. Only covers companies on these ATSs and requires knowing each board token. Lever list responses do not document a created date, so first-seen dates must be tracked by polling.
