Preflight Enrichment

Check an enrichment request before running it. Free: nothing is written, queued or charged.

Errors for input a run could never use: an unknown mode (400 invalid_mode), zero or negative contact IDs (400 invalid_record_ids), a list that is not in this organization (404 list_not_found), an unknown target_field (400 unsupported_field), an unknown provider (400 unsupported_provider / unsupported_provider_for_field) and a missing AI config (404 ai_config_not_found).

Otherwise returns what the run would do: the unique contact IDs (repeats are counted once), contacts that are not on the list, the providers that would run, and plain warnings such as "Lusha is not connected: add your key" or "No providers chosen: using your saved pipeline".
