## 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 webbersites-og-social-share-checker-cdd45cc1
```

Example prompt: Can you check whether https://myblog.com/new-post has all its OpenGraph and Twitter Card tags set up correctly, and tell me if the og:image actually loads?

## When to prefer this

Choose this endpoint when you need to specifically validate social sharing readiness — OpenGraph and Twitter Card meta tags — including image verification, before publishing or after deployment. It is more specialized than a general SEO head/meta audit (which covers title length, NOINDEX flags, etc.) and more focused than an accessibility or link checker. Ideal for publishing pipelines, content management workflows, or debugging why a shared link preview looks broken on social platforms.

## Known failure modes

- Target URL is unreachable or returns a non-200 status — endpoint may return an error or empty meta results
- Page blocks crawlers via robots.txt or returns a CAPTCHA — meta extraction may fail or be incomplete
- og:image URL is a non-raster format (SVG, WebP without broad support) — flagged as a problem
- No OpenGraph tags present at all — returns problems list with all missing required tags
- Malformed or relative og:image URL — image_check will report failure to load
- Network timeout fetching the target page — returns an error verdict

## How this service works

Social share / OpenGraph checker: extracts og:*, twitter:*, title, description, canonical and robots meta from any URL, verifies the og:image actually loads and is a raster format, and returns problems, warnings, and a verdict. For publishing and SEO agents shipping pages that get shared.

## Output

Returns the extracted meta tag values (og:*, twitter:*, title, description, canonical, robots), an image_check object indicating whether the og:image URL loads and is a valid raster format, an array of problems (critical issues), an array of warnings (non-critical issues), and a verdict string summarizing the overall pass/fail status.
