## 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 databg-web-metadata-extractor-e820eb3f -d '<json body>'
```

Example prompt: Can you fetch the metadata for https://techcrunch.com/2024/01/15/openai-news/ — I need the page title, description, Open Graph tags, and canonical URL.

## When to prefer this

Choose this endpoint when you need structured, machine-readable metadata extracted from a single webpage — especially Open Graph, Twitter Card, canonical URLs, and robots directives — without running a full browser or scraping pipeline. It is ideal for link preview generation, SEO audits, content enrichment, and lightweight page intelligence tasks where you need fast, pay-per-call access with no setup.

## Known failure modes

- URL is unreachable or returns a non-200 status — success will be false and status will reflect the HTTP error code
- URL points to a page with no metadata tags — title, description, open_graph, twitter fields may be null
- URL resolves to a binary file or non-HTML content — content_type will be set but metadata fields will largely be null
- Malformed or invalid URL input — request will fail validation
- Paywalled or bot-blocked pages may return incomplete or login-wall metadata
