Official2 toolsSSTV Decoder
Decode an SSTV audio recording and anchor its fingerprint and image hash to the Knox event chain.
Decodes SSTV audio recordings and anchors image hashes to the Knox chain.
Captured live from the server via tools/list.
decode_sstv
Demodulate a presented slow-scan-television (SSTV) audio recording, anchor the audio fingerprint and the decoded image hash to the Knox event chain, and return a self-authenticating receipt bundle (Knox anchor + C2PA-aligned envelope + FRE 902(13)/(14)-shape affidavit). Audio bytes are NOT retained — only the SHA-256 fingerprint and the decoded image are anchored. Bonis Systems does not capture audio on its own; the audio must be presented by the caller (a public WebSDR recording, a customer-controlled SDR capture they consent to submit, or audio they own). Phase 1 supports Martin M1 (VIS code 0x2C, 320×256 RGB). Other VIS codes return mode = 'unsupported' with detected hex. Requires a Knox Bearer API key on the Authorization header — unauthenticated calls are rejected.
Parameters (5)
- namestringrequired
Display name for the recording (max 256 chars).
- audioBase64stringrequired
Base64-encoded audio. Either a complete WAV file (RIFF/WAVE, 8/16/24-bit PCM or 32-bit IEEE float, mono or stereo, 4-192 kHz) or raw 16-bit signed little-endian mono PCM samples.
- audioFormatstring
Audio container ('wav' default, or 'pcm16-mono').
- sampleRateinteger
Required when audioFormat = 'pcm16-mono'.
- captureobject
Optional capture-context metadata.
verify_sstv_decode
Verify a previously anchored SSTV-decode record. Given a SHA-256 anchor hash (the payload_hash from a prior decode_sstv call), return the anchor record, predecessor hash, sequence number, and timestamp. Public — no authentication required. The verification path itself is also accessible at GET /api/knox/verify?hash=<hash>.
Parameters (1)
- hashstringrequired
SHA-256 anchor hash (64 lowercase hex chars).
