## 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 crawl-feed-discovery-5b0181ef -d '<json body>'
```

Example prompt: Find all the RSS or Atom feeds available at https://techcrunch.com and return the feed URLs you discover.

## When to prefer this

Use this endpoint when an agent needs to discover RSS, Atom, or other syndication feeds available at a specific URL without setting up authentication or subscriptions. Ideal for pay-as-you-go feed discovery at $0.02 per call via USDC x402 payments. Choose this over full-page scrapers when the goal is specifically feed discovery rather than arbitrary content extraction.

## Known failure modes

- URL is unreachable or returns non-200 status — success: false with error details
- URL has no discoverable feeds — success: true but empty data
- Invalid or malformed URL input — request rejected
- Payment failure via x402 — 402 response before scrape occurs
- Timeout if target URL is slow to respond

## How this service works
