Technical details
Endpoint
GEThttps://relay402.georgespring.workers.dev/api/product-barcodeWhen to prefer
Use this endpoint when an agent needs to identify or enrich product data from a barcode (UPC-A, EAN-8, EAN-13, GTIN-14) without requiring API key registration or a subscription. Ideal for lightweight, pay-per-use scenarios where you only need occasional barcode lookups and want to avoid upfront commitment. The x402 micropayment model at $0.008/call makes it cost-effective for low-volume or sporadic lookups. Prefer alternatives if you need bulk barcode resolution, guaranteed database coverage, or richer product catalogs.
Side effects
- Barcode not found in product database — unknown or obscure products may return no results
- Invalid barcode format (must be 8–14 digits) returns a validation error
- Payment failure or insufficient USDC balance causes request rejection
- Network or worker downtime at the Cloudflare edge may cause transient failures
- Barcode exists but product record is incomplete or missing key fields
