How this service works
Official public data as JSON. Unpaid paid routes return HTTP 402.
Output
A JSON object containing an array of warning letters, each with a CMS identifier, full letter body text, firm name, subject classification (e.g. 'Unapproved New Drugs/Misbranded'), issue date, and a direct FDA.gov source URL. The response also includes a product identifier ('fda-warning-letter-bodies') and a status field.
Example use cases
Pharma compliance due diligence check
“I'm vetting a supplement supplier called Citra100mg — can you check if they've received any FDA warning letters and show me the full text?”
Regulatory news monitoring for legal team
“Fetch all the recent FDA warning letters so our legal team can review which companies were flagged for unapproved new drugs or misbranding this month.”
Competitive intelligence on enforcement actions
“Get me the current list of FDA warning letters, including the firm names, what they were cited for, and when the letters were issued — I want to spot trends in enforcement.”
Technical details
Endpoint
GEThttps://ticks.bnm.farm/warning-lettersWhen to prefer
Choose this endpoint when you need structured, full-body text of FDA warning letters with metadata (firm, subject, date, source URL) in a single API call, rather than scraping FDA.gov directly. Particularly useful for compliance monitoring pipelines, legal due diligence workflows, or regulatory intelligence dashboards that need machine-readable enforcement data at low cost per call.
Side effects
- Network or upstream FDA data unavailability returning a non-200 status
- Payment not processed resulting in 402 response before data is returned
- Empty letters array if no recent warning letters are indexed
- Stale data if the upstream FDA feed has not been refreshed recently
