## 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 unprice-pay-meta-pay-per-request-url-metadata-fetcher-ea7369b9
```

Example prompt: Can you fetch the metadata from https://example.com and tell me the page description and key content items listed there?

## When to prefer this

Choose this endpoint when you need lightweight, structured metadata extraction from a URL (including IPFS links) and want to pay only per request in USDC without setting up a scraping infrastructure. It is especially useful for agents that need quick page summaries, link previews, or on-chain/IPFS content metadata without full HTML parsing.

## Known failure modes

- Invalid or unreachable URL returns an error or empty items array
- Payment not accepted (402 if USDC on Base not properly sent)
- URL returns non-HTML content that cannot be parsed for metadata
- Rate limiting or server-side timeout on the target URL
- IPFS CID not found or gateway timeout

## How this service works

Tiny paid web services for agents. Pay per request with USDC on Base via x402, plus non-x402 Base USDC tx-hash checkouts for Merchant Feed Audit, Base USDC receipts, and recent wallet statements.

## Output

Returns a JSON object containing the requested URL, a count of metadata items found, and an array of key-value pairs (e.g. description, title, keywords) extracted from the page. Each item has a 'key' and 'content' field.
