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 jobId and a result block containing: full transcript text, language code, timestamped speech segments (text, startSeconds, endSeconds), visible on-screen text with frame timestamps, video container format, width/height dimensions, total duration in seconds, number of sampled frames, source SHA-256 hash, any processing warnings, and a schema version identifier. Also includes economics metadata showing net, revenue, energy, and platform fee in micro-USD.
Example use cases
Legal evidence extraction from clip
“I need to extract a full transcript and all visible on-screen text from this MP4 court exhibit — it's about 45 seconds long, I own it, and I need timestamps for every spoken segment so I can cite exact moments in my brief.”
Content audit for compliance review
“Can you analyze this WebM training video and pull out everything that's spoken and any text that appears on screen? I have explicit permission to process it and need to verify it matches the approved script.”
Forensic metadata report for a video clip
“Run this MOV clip through video evidence mapping — I need the SHA-256 hash, duration, dimensions, detected language, and a timestamped transcript so I can include it in an incident report. I confirm I own the media.”
Technical details
Endpoint
POSThttps://x402.bakdupoffroad.com/v1/media/evidence-mapWhen to prefer
Choose this endpoint when you need a comprehensive structured evidence map of a video file — combining transcript, on-screen text, timestamps, and technical metadata in a single paid API call. It is particularly well-suited for legal, compliance, or forensic workflows where a verifiable SHA-256 hash and rights attestation are required. Prefer it over general transcription services when you also need visible text extraction and video dimension metadata in one response.
Side effects
- Missing or false rightsConfirmed field — request rejected
- Video exceeds 25 MiB or 120 seconds — payload too large error
- Unsupported container format (e.g. MKV without WebM compliance) — format error
- Base64 encoding malformed — parse error
- Payment via x402 not authorized or insufficient USDC balance — 402 Payment Required
- No audible speech in video — transcript returned empty with warning
- Network timeout for large uploads near the size limit
