How this service works
Private PDF preflight and authorized-video intelligence APIs paid per call with x402 USDC on Base.
Output
Returns a JSON object with a job ID, the full transcript as a single string, a list of time-stamped text segments (each with startSeconds, endSeconds, and text), the detected language code, video container type, source file SHA-256, duration in seconds, schema version, any warnings, and a cost breakdown showing revenue, platform fee, energy, and net amounts in micro-USD.
Example use cases
Meeting recording transcription
“I recorded a 90-second team standup as a .mov file and I own the recording — can you transcribe it for me and give me the timestamps for each sentence?”
Podcast clip caption extraction
“I have a 2-minute clip from my own podcast saved as an MP4 — transcribe it with start and end timestamps so I can use it for closed captions.”
Video search indexing
“I've got a short product walkthrough video (webm format, under 25 MB) that I created — extract the full spoken transcript so I can index it for search.”
Technical details
Endpoint
POSThttps://x402.bakdupoffroad.com/v1/media/transcriptWhen to prefer
Choose this endpoint when you have a short video file (under 25 MiB, under 2 minutes) in a common container format (MP4, MOV, WebM, AVI), you own or have explicit rights to the content, and you need a paid-per-call transcript with timestamped segments and a cryptographic source hash — without committing to a subscription. Ideal for agents that process occasional video clips and can pay $0.29 USDC per call via x402 on Base.
Side effects
- Missing or false rightsConfirmed field causes rejection — the boolean must be explicitly true
- Video exceeds 25 MiB or 120 seconds — request will be rejected
- Unsupported container format (e.g. not MP4/MOV/WebM/AVI) — processing error returned
- Malformed or truncated base64 payload — decoding failure
- Payment via x402 not completed or insufficient USDC balance — 402 response before processing
- No audible speech in video — empty transcript with possible warning
- Network or server error during processing — retry may be needed
