How this service works
Pay-per-call utilities for AI agents over x402, USDC on Base.
Output
Returns a JSON object containing: the task type, full transcript text, detected or specified language, video duration in seconds, word count, file format, model used (whisper-large-v3-turbo), an array of timed segments each with start/end timestamps and text, and WebVTT captions data. File size is also echoed back as bytes.
Example use cases
Meeting recording to transcript
“I've got a 15-minute team meeting recorded as an MP4. Can you transcribe it and give me the full text along with timestamped segments so I can find specific moments?”
Multilingual video captioning
“I have a Spanish-language webinar in QuickTime format — can you transcribe the audio and generate WebVTT captions for it so I can add subtitles?”
Translate foreign-language video
“I uploaded a WebM video recorded in French. Can you translate the speech into English and give me the full transcript and segment timings?”
Technical details
Endpoint
POSThttps://agents.crowdspark.me/v1/video/transcribe/upload?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you have a raw video file (MP4, MOV, WebM) available as bytes or base64 and need a complete transcript with timestamped segments and WebVTT captions in a single call. Prefer it over URL-based transcription services when the video is local or not publicly accessible. The whisper-large-v3-turbo model provides high accuracy across many languages and supports both transcription and translation tasks at a low flat cost per call.
Side effects
- File exceeds 20 MB limit — request rejected
- Unsupported video format — only MP4, QuickTime, WebM accepted
- No audio track detected in video — empty or failed transcript
- Corrupted or unreadable video bytes — parsing error
- Invalid language ISO code — may fall back to auto-detection or error
- Network timeout on large uploads — partial or failed response
