How this service works
Transcript+: audio/video URL or upload to a speaker-labelled (diarized) transcript, summary, chapters and SRT/VTT captions. Priced per audio minute.
Output
Returns a structured JSON object (or SRT/VTT/text depending on format parameter) containing the full speaker-labelled transcript with timestamps, a prose summary of the content, timestamped chapter markers, and optionally SRT or VTT caption blocks ready for upload to video platforms.
Example use cases
Meeting recording to searchable notes
“I have a recorded Zoom call at https://storage.example.com/meeting.mp4 — can you transcribe it with speaker labels, generate a summary, and break it into chapters so I can quickly navigate the key topics?”
Podcast subtitle generation
“Generate SRT caption files for this podcast episode at https://cdn.example.com/episode42.mp3 so we can upload them to our video platform — diarize it too so listeners can follow who's speaking.”
Interview transcript for journalism
“Transcribe this journalist interview audio at https://files.example.com/interview.m4a with full speaker diarization — the recording is under 30 minutes — and give me the transcript as plain text with a summary at the top.”

Endpoint
POSThttps://seenly-transcript-plus.vercel.app/api/transcribe?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need speaker-attributed (diarized) transcripts alongside summaries and chapter markers in a single call, especially for meetings, interviews, or podcasts. It accepts both remote URLs (up to 100 MB / 60 min) and small inline file uploads and outputs multiple formats (JSON, SRT, VTT, text) in one request. Prefer it over bare transcription APIs when you need the full package — diarization, summary, and captions — without chaining multiple services.
Side effects
- Audio/video file exceeds 100 MB or 60-minute limit — request rejected before payment
- Inline base64 file exceeds 4 MB limit — request rejected
- maxMinutes guard triggers if audio is longer than specified — rejected before payment
- Unsupported audio/video format or corrupted file — transcription fails
- Public URL unreachable or requires authentication — download fails
- Language hint not recognized — may fall back to auto-detection with reduced accuracy
- x402 payment not completed — endpoint returns 402 and transcription does not proceed
