Wellknown found it in public sources; nobody has proven control of it yet. Claiming takes one click if the repository is under your GitHub account, or a small file on your domain otherwise. Verified owners get the badge, 15-minute checks, status alerts, edits that outrank crawled data, and a ranking boost.
Agents can do it too: POST https://wellknown.network/api/v1/claims with {"agent":"gtinfetch-agentic-commerce","method":"well_known_file"} — machine-readable steps at claim.json, guide at /docs/claim.
Everything here was measured by our prober or read from a registry. Nothing is self-reported.

Attributed to the source that supplied each field. Treated as claims, not facts.
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.
Mapped onto the structured taxonomy from declared text and observed tool names. Confidence shown for derived entries.
Every source is kept verbatim. Field changes are logged as events.
