About

Open FDA Drug Reference (BYOK) lets an AI assistant read your own Open FDA Drug Reference data through the Open FDA Drug Reference API with a key you supply (openFDA API key). Read-only: 5 tools (search_drug_ndc_directory, search_drugsfda_applications, search_ndc_spl_data_elements, search_substance_records, count_drug_reference_records). The BYOK key travels with each request, is used for that one call only and is never stored, logged or cached; it is only ever sent to api.fda.gov. Unofficial connector by Unify Dynamics LLC: not affiliated with, endorsed by or sponsored by Open FDA Drug Reference. Open FDA Drug Reference and its logos are trademarks of their owners and are used only to say which service the connector works with.

Sources: Live from the Open FDA Drug Reference API (api.fda.gov) with a BYOK key; documentation: https://open.fda.gov/apis/drug/. Endpoints checked against that documentation on 2026-10-16.

BYOK: bring your own keyThis connector uses your own Open FDA Drug Reference openFDA API key. Create one at https://open.fda.gov/apis/authentication/, with the fewest permissions it needs (read-only if the provider offers it). Your assistant sends it in the X-Upstream-Key header with every request. It is used for that one call only: never stored, logged or cached, and only ever sent to Open FDA Drug Reference. Revoke it at the provider whenever you like. Unofficial connector: not affiliated with Open FDA Drug Reference.
