How this service works
Turn a full recording into a structured document: POST JSON with an audio_url — up to 2 HOURS of meeting, interview, hearing, or podcast audio — and get a diarized who-said-what transcript JSON: timestamps, speaker tracking with per-segment confidence, language codes. Most transcription APIs cap at ~20 minutes; this one runs Gemini long-context, built for the long ones. mp3, wav, m4a, ogg, webm, flac. Flat price, USDC on Base, no account.
Output
A JSON object containing a diarized transcript broken into segments, each with a speaker identifier, start and end timestamps, spoken text, per-segment confidence score, and detected language code — covering the full audio duration up to 2 hours.
Example use cases
Post-meeting transcript with speaker labels
“I have a 2-hour Zoom recording of our all-hands meeting at audio URL https://storage.example.com/allhands-feb2025.m4a — can you transcribe it and give me a full breakdown of who said what with timestamps so I can share notes with the team?”
Journalistic interview diarization
“I recorded a 75-minute interview with three sources for my article — the audio is at https://recordings.press/interview-march.wav. Can you transcribe it and label each speaker's segments with timestamps and confidence scores so I can quickly find each person's quotes?”
Legal hearing transcript generation
“We have a 90-minute court hearing audio file at https://legalfiles.firm.com/hearing-2025-03-15.mp3 — can you produce a structured JSON transcript with speaker diarization and timestamps so we can review who said what during the proceedings?”
Technical details
Endpoint
POSThttps://dicta-notes.com/routes/x402/transcribe-longWhen to prefer
Choose this endpoint when you need to transcribe audio longer than ~20 minutes — the typical cap for most transcription APIs — with speaker diarization included. It is specifically built for long-form content: multi-hour meetings, interviews, hearings, and podcasts where knowing who said what at each timestamp is as important as the words themselves. Prefer this over short-audio endpoints when the recording exceeds 20 minutes or when per-speaker segmentation with confidence scores is required. Payment is flat-rate USDC on Base with no account needed.
Side effects
- Audio URL unreachable or returns non-audio content — transcription fails with an error
- Audio format not supported (must be mp3, wav, m4a, ogg, webm, or flac)
- Audio exceeds 2-hour limit — request rejected or truncated
- Poor audio quality or heavy background noise reduces transcription accuracy and confidence scores
- Insufficient USDC balance or payment failure on Base — request not processed
- Speaker diarization may merge or split speakers in noisy or overlapping-speech segments
