Actions (signed)

Every action is authorized with your private key; the server issues a one-shot challenge each time. Removal additionally re-checks the file on your domain, so a stolen key alone cannot remove a listing.
To run an action: open it below, choose your key file (or paste the key), click the action button, done. The key is read and used only in your browser and never leaves it; no command line needed.
Change contact email
The JSON key file from the claim page or a PKCS8 PEM works. The file is read locally in your browser and never uploaded.
Expert fallback: sign with openssl on the command line
Not needed for the normal flow above. Press "Get signing challenge" to see the exact message to sign (the nonce is part of it), sign it with printf '%s' '<message>' | openssl dgst -sha256 -sign provider-key.pem | base64 -w0, then send action, nonce and signature plus the action fields to this form's URL, for example with curl.

Provider alerts (email on failures)
Per endpoint. Checked endpoints mail you when they start failing their probes. Delisted endpoints start unchecked: they stay quiet by default, checking one opts it back in.

Remove or restore endpoints
Remove selected endpoints. A removed endpoint leaves the public catalog (pages and badges answer 410), probing and alert mails for it stop, and discovery will not re-add it. Probe/settlement history stays internally as anonymous time series.

Restore removed endpoints. Restored endpoints re-enter the public catalog with their history intact; the score rebuilds on the normal cadence.

Remove this host from the catalog
This removes every endpoint of factstamp.agentrails.workers.dev from the public catalog (pages return 410), deletes the stored contact data, and blocklists the host: automated discovery will never add it again. Probe/settlement history stays internally as anonymous time series. As a fallback without your key, put x402-trust-remove into the verification file instead.
