## 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 agentshelf-syntexa-ch-og-type-extractor-d5368768 -d '<json body>'
```

Example prompt: Can you extract the og:type Open Graph tag from this page: https://example.com/some-article? I need to know how the page classifies itself according to Open Graph.

## When to prefer this

Use this endpoint when you specifically need the og:type Open Graph meta property from a page and want an SSRF-safe server-side fetch. Prefer the free sandbox endpoint (/v1/sandbox/profile-og-type) for testing or non-production use. Choose this paid endpoint when you need reliable, production-grade extraction with guaranteed execution.

## Known failure modes

- URL is unreachable or returns a non-200 HTTP status
- Page blocks server-side fetching (e.g. bot protection, CAPTCHA)
- No og:type meta tag present in the HTML
- URL is blocked due to SSRF safety restrictions (private/internal IPs)
- HTML input exceeds 200,000 character limit
- URL exceeds 2,048 character limit
- Malformed HTML prevents parsing

## How this service works

Call when an agent needs og:type extracted from a public page or HTML (SSRF-safe). Exact $0.007 USDC. Prefer unpaid POST /v1/sandbox/profile-og-type first.

## Output

Returns the extracted og:type value from the Open Graph meta tag found in the specified page or HTML, such as 'website', 'article', 'video', 'product', etc. If no og:type tag is found, returns an empty or null result.
