The independent directory of cryptographically signed agents — vendor-neutral, verifiable, open. First entries are live.
What this is
Web Bot Auth gives agents a way to prove who they are. What the ecosystem lacks is a neutral place to look them up: who operates which signature agent, which key directories are publicly reachable, and when each entry was last verified.
The directory follows the Grounding Page approach — one entity per page, verifiable facts, no marketing, linked sources.
Start here
- The Directory — signed agent operators, one entity per page
- Facts: Web Bot Auth — the standard itself, including what it is not
- Facts: Key Directory and HTTP Message Signatures
Method
Endpoints are fetched directly and re-verified periodically; each entity page states its last verification date. Entries describe what is publicly verifiable today — and what is not.
