## 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 cerawal-web-metadata-extractor-f251316d -d '<json body>'
```

Example prompt: Can you fetch the metadata from https://example.com/article and tell me what structured information you can extract from that page?

## When to prefer this

Choose this endpoint when you need quick, no-auth, pay-per-use metadata extraction from a URL without committing to a subscription. It's ideal for AI agent pipelines that occasionally need to fetch page metadata on demand and want to pay only for what they use in USDC via x402, avoiding API key management overhead.

## Known failure modes

- Invalid or unreachable URL returns a failure response with success: false
- Payment failure via x402 protocol blocks the request from executing
- Paywalled or JavaScript-rendered pages may return incomplete or empty metadata
- Rate limiting or bot-protection on the target site may result in partial data
- Malformed URL input causes request rejection
