Checks 1–7

Accurate transcription in seconds - 99 languages, auto-detected. Powered by Whisper. Send audio as base64 or just pass a public audio_url (wav/mp3/m4a/ogg/webm, up to 3 minutes); returns the transcript with language confidence and optional timestamps. Failed calls are never charged. For audio over 3 minutes, use Speech-to-text — long-form.

A declared endpoint responds to a probe. Not implemented yet, so nobody passes or fails it.

outside the census

Everything above is one sweep, pinned to one block. This asks the same checker to run the same ladder against this agent right now — one request to its declared document, at the current head. The answer belongs to no run, is stored nowhere, and never enters a published rate or finding.
