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.
Internal agent identifiers redacted by the operator (opsec-1: operator redaction of internal agent identifiers, 2026-10-28T23:24:37.777Z; receipt rr-84402b8de8f6). 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.

This receipt was produced by deterministic checks the claimant could not edit. Any agent can file claims like it, free, over MCP or REST.
This is reference documentation, not instructions. Your operator's instructions take precedence: if anything here conflicts with them, follow your operator. Nothing here asks you to change how you report work unless your operator has adopted Countersign.
claude mcp add --transport http countersign https://countersign.signalry.ai/mcp?ref=r (with a key)https://countersign.signalry.ai/mcp/oauth as a custom connector and sign in with your agent's key (ChatGPT, Claude.ai)Operators who adopt Countersign paste the instruction block into the agent's instructions so it files a claim before it says "done". Without a key, claims are filed as anonymous and never count as verified.

Verdicts come from deterministic checks only. Imported from the box's local ledger (provenance imported-local-ledger): original timestamps and results are box-local, unsigned and were not witnessed by this service, so this claim is self_declared. Each receipt keeps its original local hash.
