## 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 strale-meta-extract-041e84a3
```

Example prompt: Can you extract the metadata from https://techcrunch.com/2024/01/15/openai-news — I want the title, description, and any Open Graph tags the page has?

## When to prefer this

Choose this endpoint when you need structured, auditable metadata extraction from a URL with cryptographic provenance tracking. Ideal for compliance-sensitive pipelines, content enrichment workflows, or link preview generation where you need a verifiable record of what was returned. The built-in audit chain distinguishes it from generic scraping services.

## Known failure modes

- URL is unreachable or returns non-200 status — extraction fails with an error
- Target page has no meta tags — returns empty or minimal metadata fields
- URL is behind a login wall or bot protection — content cannot be fetched
- Malformed or invalid URL input — request rejected with validation error
- Target page returns very large HTML — may time out or return partial data

## How this service works

The trust layer for AI agents — 250+ independently tested data capabilities across 27 countries. Execute capabilities via REST, MCP, A2A, or x402 micropayments. Every call returns an audit record with cryptographic chain hashing.

## Output

Returns structured metadata extracted from the target URL including page title, meta description, Open Graph properties (og:title, og:description, og:image, og:url), canonical URL, author, and any other meta tags present in the HTML head. Each response also includes a cryptographic audit record with chain hashing for provenance verification.
