## When to prefer this

Use this endpoint when you need keyless, pay-per-call access to the FDA openFDA food adverse events dataset without setting up an FDA API key. Ideal for AI agents in pharma, food safety, device safety, or regulatory research contexts that need structured adverse event data on-demand. Prefer this over direct openFDA access when operating in an agentic x402 payment flow or when API key management is not feasible.

- No matching records found for the query returns empty result set
- Upstream openFDA API unavailability causes request failure
