Verified against Clay's live public integration catalog on 2026-10-17. The catalog data-point list is integration-wide; a particular action may return only a subset. No separate field-level Clay University output section was found in the public documentation corpus; do not infer undocumented fields. Coverage, freshness, geography, credit cost, and BYO-account requirements vary by action and plan. Estimated or inferred values should be validated before investment, legal, credit, or other high-stakes decisions.
