Example prompt: Can you pull the social share metadata for https://openai.com — I want to see the Open Graph title, description, image, canonical URL, author, and favicon all in one place?

## When to prefer this

Use this endpoint when you need to quickly inspect how a URL will render as a social share card — including Open Graph and Twitter Card tags — without building a custom scraper. Ideal for SEO audits, CMS link-preview features, content moderation pipelines, or any workflow that needs normalized social metadata from arbitrary URLs.

## Known failure modes

- URL points to an internal/private IP address — blocked for security, returns error
- URL is unreachable or returns a non-200 HTTP status
- Page has no Open Graph or Twitter Card tags — returns partial metadata with only available fields
- Malformed or invalid URL input — returns validation error
- Page requires authentication to access — returns limited or empty metadata

## How this service works

Social share metadata lookup: reads a web page's title, canonical link, favicon, author, and social-card tags (Open Graph and Twitter formats) and returns them as one normalized JSON object. Safe against internal-address requests. Handy for SEO checks, content management systems, and any tool that needs to know how a URL will look when shared.

## Output

A normalized JSON object containing the page's title, canonical link, favicon URL, author, and all Open Graph and Twitter Card meta tags extracted from the given URL.
