## 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-og-metadata-fetcher-6ac4538f
```

Example prompt: Can you fetch the Open Graph metadata — title, description, and preview image — for https://example.com so I can use it in a link preview card?

## When to prefer this

Choose this endpoint when you need quick, pay-per-use Open Graph / link preview metadata extraction without managing your own scraping infrastructure. Ideal for one-off or low-volume link enrichment tasks billed per request in USDC via x402, especially in crypto-native or agent-wallet contexts. Not suited for high-volume bulk crawling or pages requiring JavaScript execution.

## Known failure modes

- Target URL is unreachable or returns non-200 status — metadata fields will be empty or call will error
- Page has no Open Graph tags — title/description/image fields return empty strings
- Invalid or malformed URL parameter — request may fail or return unexpected results
- Payment failure — call blocked if USDC payment on Base via x402 does not go through
- Target page blocks scraping or requires JavaScript rendering — returned metadata may be incomplete

## 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

A JSON object containing the page's Open Graph metadata: the canonical URL, page title, description text, and OG image URL. Fields may be empty strings if the page does not expose that metadata.
