## 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-image-type-extractor-96b4fb4d -d '<json body>'
```

Example prompt: What is the og:image:type declared on https://example.com — can you extract it from the page's Open Graph meta tags?

## When to prefer this

Use this endpoint when you need to extract specifically the og:image:type Open Graph meta tag from a public webpage or raw HTML, with SSRF safety guaranteed. Prefer the free sandbox endpoint /v1/sandbox/profile-og-image-type first for testing. Choose this over general HTML scrapers when you only need OG image type metadata and want a minimal, purpose-built extraction with predictable pricing.

## Known failure modes

- Page at URL is unreachable or returns non-200 status
- URL points to a private/internal address (blocked by SSRF protection)
- Page has no og:image:type meta tag — returns empty or null value
- HTML input exceeds 200,000 character limit
- URL exceeds 2,048 character limit or is malformed
- Payment of $0.008 USDC not provided or rejected

## How this service works

Call when an agent needs og:image:type extracted from a public page or HTML (SSRF-safe). Exact $0.008 USDC. Prefer unpaid POST /v1/sandbox/profile-og-image-type first.

## Output

Returns the value of the og:image:type Open Graph meta tag found in the page (e.g. 'image/jpeg', 'image/png', 'image/webp'), or an empty/null result if the tag is not present. The endpoint fetches the page if a URL is provided, or parses the supplied HTML directly, with SSRF protections in place.
