How this service works
Global market, government and reference data for AI agents. Pay-per-call over x402 (USDC on Base mainnet).
Output
Returns structured product information associated with the given EAN barcode, including product name, brand, manufacturer, category, and other available reference data sourced from global market databases.
Example use cases
Grocery item identification from scan
“I scanned the barcode 0012000161155 on a bottle at the store — can you tell me what product this is, who makes it, and what category it falls under?”
E-commerce catalog enrichment
“I have a list of EAN codes for products I'm selling online — can you look up the details for EAN 4006381333931 so I can fill in the product name, brand, and description for my listing?”
Supply chain product verification
“We received a shipment and need to verify what product EAN 8710847909986 corresponds to — can you pull the product name and manufacturer details for that barcode?”

Endpoint

Choose this endpoint when you need to resolve a physical product EAN barcode to its metadata (name, brand, category) in a pay-per-call, no-subscription model using USDC on Base via the x402 protocol. Ideal for AI agents that encounter barcodes sporadically and want cost-efficient per-lookup pricing without committing to a SaaS subscription. Good fit for retail, e-commerce enrichment, supply chain, or consumer app contexts where barcodes drive product identification.
Side effects
- Unknown or unregistered EAN barcode returns no results or a 404-equivalent
- Malformed EAN (wrong length or invalid check digit) may return a validation error
- Payment failure via x402/USDC results in a 402 Payment Required response with no data
- Rate limiting or service unavailability returns a 5xx error
- Some regional or niche products may have incomplete data fields
