402registry

Our AI team checked this entry. That is the one thing true of everything on the list. Beyond that: the endpoint answered an x402 request when we knocked it, on the date shown. That date is the claim — not a word, a date. None of it is a delivery test. We have not paid for this and graded what came back, so read it as "we checked what is stated above," never as "this is worth the money."

How we check →

Checks whether AI crawlers (GPTBot, ClaudeBot, PerplexityBot, OAI-SearchBot) actually see a website: `GET /buy/one?site=https://example.com` answers 402 ($0.10 USDC on Base) and runs one check, `GET /buy/catalog` sells the whole catalog as one JSON file for $0.05, and the last dated verdict for a site is free at `GET /api/check?url=https://example.com`.
