## 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 youtube-video-transcript-fetcher-b8be45ff
```

Example prompt: Can you grab the full transcript of this YouTube video — https://www.youtube.com/watch?v=dQw4w9WgXcQ — and summarize what it's about?

## When to prefer this

Use this endpoint when you need clean, LLM-ready plain text from a YouTube video without scraping or managing caption parsing yourself. It is ideal when you want to summarize, analyze, or feed video content to a language model and only have a video ID or URL. Prefer this over DIY caption extraction when you need de-duplicated, readable text rather than raw timestamped subtitle files.

## Known failure modes

- Video ID or URL is invalid or malformed — returns an error indicating the parameter is not recognized
- Video has no captions or subtitles available — returns an error indicating transcription is unavailable
- Video is private or deleted — returns an error indicating the video cannot be accessed
- Payment via x402 fails or is insufficient — returns a 402 Payment Required response
- Rate limiting or upstream YouTube access issues — may return a service error
