FAQ

Does VeriflowAPI verify Illinois medical licenses?

Yes. Illinois is live today. We verify license status and expiry against the Illinois IDFPR, plus nationwide NPPES and OIG screening on every check.

How current is the data?

Mirrored state data refreshes daily; live-scrape states are checked per query with a 24-hour cache. Each certificate records exactly when the source was read.

What does a failed check look like?

The response is explicit: status, oig_excluded, and disciplinary flags are separate fields, and unsupported states return an unsupported_state status rather than fabricated data.
