## 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 x402vid-youtube-topic-analyzer-fe0ee434 -d '<json body>'
```

Example prompt: Can you research 'prompt engineering for beginners' by analyzing 5 YouTube videos on that topic and give me a synthesized report on what they cover?

## When to prefer this

Choose this endpoint when you need to aggregate and synthesize intelligence across multiple YouTube videos on a single topic, rather than analyzing a specific video URL. It is ideal for broad topic research, trend discovery, or summarizing what video creators collectively say about a subject. Prefer it over single-video analysis tools when cross-video synthesis and a structured research report are the goal.

## Known failure modes

- No videos found for the given search_term — empty videos_analyzed array returned
- num_videos exceeds maximum of 5 — request rejected or capped
- search_term missing or empty — validation error returned
- Payment not completed or insufficient USDC — 402 Payment Required response
- YouTube access or rate limit issues on the provider side — upstream error
