How this service works
Pay-per-call crypto, RWA, federal, SEC, and compliance APIs. Settled in USDC on Base via x402. Hyphen routes only (e.g. /x402/rwa-aggregates, /x402/gas-tracker).
Output
Returns a collection of FDA warning letters including details such as the issuing office, recipient company or individual, subject matter, date issued, and letter content or reference — enabling regulatory compliance review and enforcement monitoring.
Example use cases
Due diligence on supplier compliance
“I'm vetting a potential food supplier — can you fetch any FDA warning letters associated with their industry so I can check their compliance history before we sign a contract?”
Monitoring pharma regulatory risk
“Pull the most recent FDA warning letters for pharmaceutical manufacturers so I can flag any companies in our portfolio that have received enforcement notices.”
Regulatory research for compliance report
“I need to compile a summary of recent FDA warning letters issued for dietary supplements — can you retrieve that data so I can include it in our quarterly compliance report?”

Choose this endpoint when you need programmatic, pay-per-call access to FDA warning letter data settled via crypto (USDC on Base) without a subscription, particularly useful for AI agents that need on-demand regulatory compliance lookups for due diligence, risk monitoring, or research workflows. Prefer this over manual FDA.gov searches when automation and structured data output are required.
