AuthProof runs on your own machine — the client starts it, so there is no endpoint to ping. 37 installs a week from npm.
Signed, non-replayable API auth. Agents self-register and sign requests with ERC-8128.
The linked repository no longer exists on GitHub — it was deleted or made private.
Quiet is not dead — but it is worth knowing when it wakes up, or when someone else takes it over. We watch the repository and tell you either way.
