How this service works
Which FDA-regulated firms have an open FDA warning letter? Search the FDA Warning Letters index by company, product area (drugs, devices, biologics, food, dietary-supplement, cosmetics, tobacco, veterinary), issuing office, subject (CGMP, adulterated, misbranded), open/closed status, or issue/posted date. Returns the recipient firm (entity-resolved where possible), issuing office, subject, and response/close-out dates — a documented compliance gap and remediation trigger.
Output
Returns a paginated list of FDA warning letter records matching the query, each including the recipient firm name (entity-resolved where possible), the issuing FDA office or district, the letter subject and alleged violation type, issue date, posted date, and any response or close-out dates indicating open or resolved compliance status.
Example use cases
Supplier compliance due diligence
“Before we sign this contract, can you check if NovaPharma Solutions has any open FDA warning letters, especially for CGMP or adulteration issues in their drug manufacturing?”
Monitoring dietary supplement brands
“Pull all open FDA warning letters for dietary supplement companies issued since January 1, 2024, sorted by letter date descending — I want to see who's had recent enforcement action.”
Competitive intelligence on device makers
“Which medical device companies received FDA warning letters from the Center for Devices and Radiological Health in the past year that are still open and haven't been responded to?”

Endpoint
GEThttps://api.govparse.io/v1/fda/warning-letters/searchWhen to prefer
Choose this endpoint when you need structured, filterable access to FDA Warning Letters with entity resolution, especially for compliance screening of suppliers or counterparties, regulatory monitoring workflows, or due diligence pipelines. Prefer over manual FDA website searches when you need machine-readable results, date-range filtering, or the ability to pivot to a resolved business entity ID across other govparse.io datasets.
Side effects
- Company name not found — returns empty results if name spelling differs significantly from FDA index
- No results for very recent letters not yet indexed or posted by FDA
- Invalid product_area enum value returns an error or empty set
- Date format errors if not supplied as YYYY-MM-DD
- Rate limits or payment failures via x402 protocol returning 402 status
- entity_id pivot may return no results if entity resolution has not been performed for a firm
