The verification layer for the agentic web. Fetches a website from outside its network as each named AI and search crawler and reports what each one actually received - status, bytes, content type and whether a 200 carried the file or a challenge page - as a signed answer an agent can verify before…
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":"crawlcheck-crawlcheck","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.

The verification layer for the agentic web. Fetches a website from outside its network as each named AI and search crawler and reports what each one actually received - status, bytes, content type and whether a 200 carried the file or a challenge page - as a signed answer an agent can verify before it reads, cites or acts.
Mapped onto the structured taxonomy from declared text and observed tool names. Confidence shown for derived entries.
