## 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-compare-channels-a007369b -d '<json body>'
```

Example prompt: Compare these three YouTube channels — @MrBeast, @MarkRober, and @Veritasium — and tell me which one is performing best in the science and education niche.

## When to prefer this

Choose this endpoint when you need a structured, AI-synthesized side-by-side comparison of 2-3 YouTube channels — especially useful for competitive research, sponsorship decisions, or content strategy. Unlike raw YouTube API data, this returns an opinionated comparison report powered by Muse Spark 1.3. Prefer this over individual channel lookup endpoints when the user explicitly wants channels ranked or contrasted against each other.

## Known failure modes

- Invalid or non-existent channel handle/URL returns error or empty channel data
- Fewer than 2 or more than 3 channels provided may fail schema validation
- Payment failure (insufficient USDC balance) results in 402 response before processing
- Private or terminated YouTube channels may not return data
- Ambiguous handles that match multiple channels may return incorrect results
