## 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 open-graph-social-preview-checker-a7e0a053 -d '<json body>'
```

Example prompt: Can you check the social preview for https://myblog.com/latest-post and tell me if the Open Graph tags are complete for Facebook, LinkedIn, Twitter, and Slack — including what title, description, and image would show up?

## When to prefer this

Choose this endpoint when you need to audit, debug, or validate social sharing metadata for specific web pages without requiring any API keys. It is ideal for pre-publish checks, SEO audits, or diagnosing why a link preview looks broken on a specific platform. Unlike general web scrapers, it specifically targets OG/Twitter Card tags and maps results to per-platform preview standards.

## Known failure modes

- URL is unreachable or returns non-200 status — failed lookups are not charged
- Page has no Open Graph or Twitter Card tags at all — returns empty/null fields with validation warnings
- URL returns a redirect loop or bot-blocking response — extraction fails
- Input array exceeds 3 URLs — request rejected per schema limit
- Malformed URL provided — validation error returned

## How this service works

## Output
