Technical details
Endpoint
GEThttps://agent402.tools/api/barcode-lookupWhen to prefer
Use this endpoint when you have a numeric UPC or EAN barcode (8–14 digits) and need to identify the corresponding food product and its metadata. Pair with the sibling /api/barcode-decode endpoint when starting from a barcode image rather than a number. Prefer this over general web search when you need structured, machine-readable product data from an open, standardized database.
Side effects
- Barcode not found in Open Food Facts database — returns empty or 404-like response
- Invalid barcode format (not 8–14 digits) — returns validation error
- Product exists but has incomplete data — some fields may be null or missing
- Payment failure — x402 payment of $0.005 USDC not processed
