How this service works
Verify an FDA drug record: given a claim_type (approval, ndc, or recall) and its identifier, does that record actually exist, and does the given name match the canonical record? Checked against openFDA. Catches a fabricated or misattributed drug approval, NDC listing, or recall citation. Existence/status only, not medical advice.
Output
Returns whether the specified FDA record (approval, NDC, or recall) exists in openFDA, whether the provided expected_name matches the canonical record's name, and any relevant mismatch or non-existence flags. Does not provide medical advice, only existence and name-match status.
Example use cases
Auditing AI-generated drug citations
“I got a research summary from an AI that cites FDA approval number NDA209637 for a drug supposedly approved by AstraZeneca — can you check if that approval actually exists and whether AstraZeneca is really the sponsor?”
Validating NDC code in a formulary
“We have NDC code 0069-0154-30 listed in our formulary as a Pfizer product — can you confirm this NDC actually exists in FDA records and the name matches?”
Confirming a drug recall citation
“I found a reference to FDA recall number Z-1234-2022 attributed to 'Strides Pharma' — please verify that recall number is real and that Strides Pharma is actually the recalling firm.”
Technical details
Endpoint
POSThttps://goodsong.dev/verify/drugWhen to prefer
Use this endpoint when an AI agent, researcher, or automated pipeline needs to fact-check a specific FDA drug record citation — particularly to detect hallucinated or misattributed drug approvals, NDC codes, or recall numbers. Prefer it over general web search when you need a deterministic, structured existence-and-name-match check directly against the openFDA database rather than a human-readable document retrieval.
Side effects
- Record not found in openFDA — identifier may be fabricated or incorrectly formatted
- Name mismatch — the identifier exists but the expected_name does not match the canonical record
- Invalid claim_type value supplied outside the allowed enum
- openFDA API unavailable or rate-limited, causing lookup failure
- Malformed identifier format (e.g. wrong NDC format) causing no results
