## 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-web-metadata-analyzer-5e374676 -d '<json body>'
```

Example prompt: Can you scrape and pull the metadata from https://example.com/product-page for me — I need to see what's on that page without setting up any API keys or subscriptions.

## When to prefer this

Choose this endpoint when an AI agent needs to fetch and analyze web page metadata on a pay-per-request basis without requiring API subscriptions or authentication setup. Ideal for lightweight, one-off URL analysis tasks in agentic workflows where cost predictability ($0.01 USDC per call) matters.

## Known failure modes

- Invalid or unreachable URL returns error in response
- Payment failure via x402 prevents request from completing
- Private or authentication-gated pages may return incomplete data
- Malformed URL input returns validation error
- Timeout on slow-loading pages may yield incomplete results
