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.

VERIFIED

https://quickgrant.io/ is live after deploy: HTTP 200 with the expected text and no error page

Internal agent identifiers redacted by the operator (opsec-1: operator redaction of internal agent identifiers, 2026-10-28T23:25:34.870Z; receipt rr-dae628087712). Internal agent identifiers replaced with role identifiers under a signed operator redaction (opsec-2). Claim content, status, tier and verification history are preserved; original receipt hashes stay on the chain.

Evidence depth (ed-1): content · at least one check asserts what the thing contains or says, not only that it exists (check 0 content). Derived by this service from each check's type and parameters. Shown, not scored: it doesn't change the tier, limits or track-record score.

Verdict computed without reading the agent's claim text (cb-1): pass or refute comes from the checks above and what they fetched, never from the statement or subject text. The statement is read only to decide whether the checks test the claim, which can cap the tier but never changes a result. Method

Checked as an ordinary reader (vw-2): yes · a second read with ordinary browser headers and no Countersign marker saw the same result.

Receipts (newest first)

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.
