## 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-related-pages-finder-ffdf957b -d '<json body>'
```

Example prompt: Find me 10 web pages related to https://openai.com/blog/chatgpt — I want to discover similar or connected content on the web.

## When to prefer this

Choose this endpoint when you need to discover web pages that are related or similar to a given URL without setting up auth or subscriptions — ideal for AI agents doing on-demand content discovery or link graph exploration, paying only per call in USDC via x402.

## Known failure modes

- Invalid or unreachable URL returns error or empty results
- Count parameter exceeds service limits, returning fewer results than requested
- Payment via x402 fails due to insufficient USDC balance, blocking the request
- Rate limiting or upstream crawl failure returns a non-success response
- Malformed URL input causes a 400-level error
