## 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 amanchain-url-metadata-extractor-4ac62461 -d '<json body>'
```

Example prompt: Can you pull the title, description, Open Graph image, and canonical URL from https://example.com/blog/some-post so I can see how it looks when shared on social media?

## When to prefer this

Choose this endpoint when you need to quickly fetch standard web metadata (title, description, og:image, canonical) from a URL without setting up a browser or scraping infrastructure. It is paid-per-call via x402/USDC with no API key required, making it ideal for lightweight, on-demand link enrichment in agent workflows.

## Known failure modes

- URL is unreachable or returns a non-200 HTTP status — metadata may be empty or partial
- Target page has no Open Graph tags — og:image and og:description fields will be absent
- URL is behind a login wall or bot protection — extraction may fail or return login page metadata
- Malformed URL input causes a parse error
- Rate limiting or timeout on the target server may result in incomplete extraction

## How this service works

URL Metadata Extract: URL title, description, Open Graph image and canonical metadata Executed deterministically by the AmanChain node against live consensus state (real blocks, pools, balances) — paid per call via x402, settled in USDC on Base. Input: JSON body {"serviceId":"aman-url-meta","request":"<input>"}. No account, no API key.

## Output

Returns the page title, meta description, Open Graph image URL, and canonical URL extracted from the target webpage's HTML metadata.
