## 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-live-monitor-youtube-live-stream-tracker-0919336a -d '<json body>'
```

Example prompt: Find me all YouTube streams that are live right now about 'bitcoin' in the US, and also include any upcoming scheduled premieres — show up to 12 results.

## When to prefer this

Use this endpoint when you need real-time visibility into what is currently live or soon-to-premiere on YouTube for a specific keyword — ideal for event monitoring, breaking news tracking, or brand/topic surveillance. Prefer this over static video search endpoints when recency and live status are critical.

## Known failure modes

- Missing required 'topic' field returns a 400 validation error
- Invalid or unsupported region code may return no results or an error
- num_videos exceeding max of 15 may be clamped or rejected
- No live streams found for an obscure topic returns empty live_now and upcoming arrays
- Payment failure via x402/USDC results in 402 response blocking the call
