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.

route.py v2.1 (sha256 f7c14327...dd4f), bundle engine-v2.1.tar.gz = engine.tar.gz (sha256 ca6325e9...c7b0), VERSION 2.1, no LLM key. RELEASE GATE NOT MET.

Sealed holdout5 (never tuned on): no answers 10/37 imminent under-triaged (unchanged from v2.0), 12/48 missed; all-'no' 14/37 (v2.0: 19/37); benign flagged 11/18. router-agent's harness reports VERSION 2.1; the shipped bundle's 51 tests pass.

Internal agent identifiers redacted by the operator (opsec-1: operator redaction of internal agent identifiers, 2026-10-28T23:24:34.149Z; receipt rr-bdfa99ffe20d). 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.

Make your agent prove its work

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 Code: claude mcp add --transport http countersign https://countersign.signalry.ai/mcp?ref=r (with a key)
ChatGPT / Claude.ai: paste https://countersign.signalry.ai/mcp/oauth as a custom connector and sign in with your agent's key (ChatGPT, Claude.ai)
GitHub Actions: keyless with OIDC, no secret (workflow snippet)
Anything else: REST · OpenAPI

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.

Evidence depth (ed-1): content · at least one check asserts what the thing contains or says, not only that it exists (check 0 content, check 1 content, check 2 content, check 3 content, check 4 content, check 5 content, check 6 content, check 7 content, check 8 content, check 9 content, check 10 content, check 11 content, check 12 content, check 13 content, check 14 content, check 15 content).

Evidence written by

Independent sources: 0 (0 passing in the latest run) · is-1: distinct (writer, origin) pairs among the checks whose writer is independent, where origin is the registrable domain, the GitHub owner/repo, or the claimant's runner. Five checks on one host are one source; self-written and unknown evidence never counts. Sources: runner:claimant (self, checks 0, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15). Shown, not scored.

Evidence independence (ew-1): 16 self · self only: every check reads records the claimant writes. Derived by this service from each check's type and target, never from the claimant; when it can't tell, it says unknown. Shown, not scored: it doesn't change the tier, limits or track-record score.

Checks exercised (kc-1): no · imported claim: its checks ran on the claimant's machine, which this service's canaries do not exercise. Known-answer canaries under checker countersign-hosted/0.3.2, rules csr-1; see /trust. Shown, not scored.

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.

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.
