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.

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 existence, check 5 existence, check 6 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.

What this receipt does not show (nr-1)

9 gap(s) beyond the two boundaries every receipt has. 0 not run, 10 not checked. Derived by this service, never by the claimant. Shown, not scored.

Content not checked (check 4) · not_checked: shows the file exists, not what it contains
Content not checked (check 5) · not_checked: shows the file exists, not what it contains
Not independent (check 0) · not_checked: reads records the claimant writes (observed and signed on the claimant's runner; this service did not observe the target)
Not independent (check 1) · not_checked: reads records the claimant writes (observed and signed on the claimant's runner; this service did not observe the target)
Not independent (check 2) · not_checked: reads records the claimant writes (observed and signed on the claimant's runner; this service did not observe the target)
Not independent (check 3) · not_checked: reads records the claimant writes (observed and signed on the claimant's runner; this service did not observe the target)
Not independent (check 4) · not_checked: reads records the claimant writes (observed and signed on the claimant's runner; this service did not observe the target)
Not independent (check 5) · not_checked: reads records the claimant writes (observed and signed on the claimant's runner; this service did not observe the target)
Not independent (check 6) · not_checked: reads records the claimant writes (observed and signed on the claimant's runner; this service did not observe the target)
Statement beyond the checks · not_checked: only what the checks assert was checked; anything else the statement says is unverified (verdicts never read the statement, cb-1)

Rerun it yourself (rr-1)

4 of 7 checks can be rerun by anyone with public tools. You don't have to trust this service: run the command and compare the output with the check's assertions above. Derived by this service, never by the claimant. Shown, not scored.

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). Shown, not scored.

Check 0 (http getagentdepot.com): the claimant (self) · observed and signed on the claimant's runner; this service did not observe the target
Check 1 (http getagentdepot.com): the claimant (self) · observed and signed on the claimant's runner; this service did not observe the target
Check 2 (http getagentdepot.com): the claimant (self) · observed and signed on the claimant's runner; this service did not observe the target
Check 3 (http registry.modelcontextprotocol.io): the claimant (self) · observed and signed on the claimant's runner; this service did not observe the target
Check 4 (file_exists): the claimant (self) · observed and signed on the claimant's runner; this service did not observe the target
Check 5 (file_exists): the claimant (self) · observed and signed on the claimant's runner; this service did not observe the target
Check 6 (git): the claimant (self) · observed and signed on the claimant's runner; this service did not observe the target

Evidence independence (ew-1): 7 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 · runner claim: its checks ran on the claimant's machine, which this service's canaries do not exercise (kinds: http_contains, http_status). 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. Runner receipts were observed on the signer's machine, not by this service; their tier is capped accordingly.
