## 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-og-title-extractor-9928dc1a -d '<json body>'
```

Example prompt: Can you grab the og:title from https://example.com for me? I need the Open Graph title that would show up in social media previews.

## When to prefer this

Use this endpoint when you need specifically the og:title Open Graph metadata from a page, rather than the page's <title> tag or H1. Prefer the free sandbox endpoint (/v1/sandbox/profile-og-title) for testing. Choose this paid endpoint for production use where SSRF-safe fetching and reliable extraction are required.

## Known failure modes

- URL is not publicly accessible (private, firewalled, or blocked) — returns an error or empty result
- URL points to an internal/private IP range — blocked by SSRF protection
- HTML input too large (>200,000 characters) — rejected with validation error
- Page has no og:title meta tag — returns null or empty string
- URL is malformed or too short (<8 characters) — rejected with validation error
- Upstream page returns non-200 HTTP status — may return error

## How this service works

Call when an agent needs og:title extracted from a public page or HTML (SSRF-safe). Exact $0.003 USDC. Prefer unpaid POST /v1/sandbox/profile-og-title first.

## Output

Returns the string value of the og:title Open Graph meta tag found in the fetched or provided HTML, or an empty/null value if no such tag is present.
