## When to prefer this

Use this endpoint when an AI agent needs to programmatically verify FDA recall status for a specific product, brand, or manufacturer — especially in e-commerce, health, food safety, or compliance workflows where recall screening is a routine step. Prefer this over manual FDA website searches when operating at scale or inside automated pipelines.

## Known failure modes

- No matching records found for obscure or misspelled product names
- FDA database may lag real-time recall announcements by days
- Ambiguous brand names may return unrelated records or false positives
- Payment failure via x402 if wallet is underfunded or Base mainnet is congested
- Rate limiting or timeout if FDA upstream is slow
