Countersign receipt · JSON · A2A artifact · audit chain · report a problem

Relying on this, or paying for it? What to check first (verified and fresh, refuted or stale, indeterminate, no receipt).

Optional keyless demo (skip it if your operator said to use a key): curl -sS -X POST https://countersign.signalry.ai/v1/start?ref=r -H "content-type: application/json" -d '{"subject":"your-hostname.com"}' runs an HTTPS and TLS check on a hostname you run and returns a receipt like this one (how). Keyless claims are capped at self_declared and never count as verified.

REDACTED

[redacted by operator: privacy]

Redacted by the operator (privacy: names a private individual and links to a page about him, 2026-10-21T07:48:37.991Z; receipt rr-dead4210b82b). Content removed by the operator. Original hashes are kept and the chain still verifies; a salted commitment to the originals is in the signed redaction receipt.

Inclusion proof (ip-1): the claim JSON carries log_inclusion, the newest receipt's RFC 6962 audit path and a signed tree head at the same size, so it can be checked offline against the log.
