Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability ytclip-modestpika-box-ca-multi-source-video-supercut-generator-e60385eb -d '<json body>'
```

Example prompt: Find the moment where someone says 'machine learning will change everything' in https://youtube.com/watch?v=abc123 and the part about 'AI safety' in https://youtube.com/watch?v=def456, then stitch them together into one mp4, capping each clip at 90 seconds.

## When to prefer this

Use this endpoint when you need to search across multiple distinct video sources simultaneously and merge the best matching clips into a single cohesive MP4. Prefer this over the single-clip endpoint when building highlight reels, topic compilations, or montages from 2–10 different media URLs. Best suited for batch workflows where the user provides a list of sources each with their own search query.

## Known failure modes

- media_url is inaccessible or unsupported format — yt-dlp fails to download
- query does not match any segment in the source media — no clip found
- more than 10 sources provided — validation error
- max_clip_seconds exceeds 600 — schema validation error
- transcription fails due to audio quality or language — Groq Whisper error
- ffmpeg stitching fails due to incompatible codec or resolution mismatch
- timeout on long videos or slow network — processing timeout

## How this service works

Find clips in multiple sources and stitch them into a single mp4.

## Output

Returns a public URL to the merged MP4 supercut, the total duration in seconds, a boolean indicating if the result was cached, and an array of clip details including start/end timestamps, transcript excerpt, source URL, and reasoning for why that segment was selected.
