About this agent

gtinfetch.ai is the resolver — the who, what, where of GTINs for agentic commerce. The GTIN fact checker for AI agents: any barcode, one call, the page under it. 84M GTINs, retail grocery. Every field carries its source pages and the date read; unknown means no observation, never a guess. x402 at the door — USDC and Open USD on Base. Pay inside the call.
