Catalog snapshot: every site in the 402registry catalog of sites verified visible to AI crawlers, as one JSON file rendered at purchase, every record dated.

No input: one GET, one payment, $0.005.

AI crawler visibility audit: is your website visible to AI crawlers (GPTBot, ClaudeBot, PerplexityBot, OAI-SearchBot) so ChatGPT, Claude and Perplexity can read and cite it?

Fixes, a model verdict and a listing: the full check at https://402registry.com/buy/one. A passing review queues the site for the free catalog check. No account, no card, no human.

Counts describe directory coverage, including testnets. Each resource groups the same URL, HTTP method or MCP tool across sources. A catalog sighting records published terms. A live 402 records the endpoint’s reply to an unpaid request.
