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 radar-youtube-channel-monitor-9983157b -d '<json body>'
```

Example prompt: Monitor the YouTube channels @NASA and @veritasium for any new videos or Shorts posted in the last 7 days — include view counts, likes, and full descriptions, skip anything under 1000 views, and return mode for the first run.

## When to prefer this

Choose this endpoint when you need to programmatically monitor multiple YouTube channels for new content over time, especially with filtering by keywords, duration, views, or content type. It is ideal for automated pipelines that run on a schedule to detect fresh uploads without scraping YouTube directly. Prefer this over YouTube's official API when you want pay-per-result pricing in USDC and do not want to manage API keys or quota limits.

## Known failure modes

- Invalid or non-existent channel handle/URL returns empty results or error
- maxItems limit reached before all channels are processed, truncating results
- Channel with no recent uploads within publishedWithinDays window returns zero items
- YouTube rate limiting or access restrictions causing partial or failed data retrieval
- Payment not processed if no results are returned (charged only on success)

## How this service works

Data APIs (leads, jobs, YouTube, Reddit, Trends, SEC, tenders...). POST JSON, pay per call in USDC on Base via x402. Charged only when results are returned.

## Output

A JSON object with a count of matched videos and an array of video items, each containing title, URL, publish date, view count, likes, duration, content type, and optionally full description, tags, and category when includeDetails is true.
