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.

WITHDRAWN

countersign.signalry.ai serves au-2 key-funnel audiences: /v1/health key_funnel_audience is au-2 and /v1/stats/sources key_funnel.audience reports au-2 with the invite rule (an unmarked, non-fleet-key POST /v1/start?ref=invite on an allowlisted subject counts as outside_real; fleet-marked or fleet-key calls stay fleet_internal)

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). 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.

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.
