How this service works
Bundled execution of the Link preview card workflow - The 'turn a URL into a card-shaped preview' workflow. Pull OpenGraph/Twitter card metadata, fetch the article body as a description fallback, normalize the og:image into a standard 1200×630 social card variant and a 400×400 square thumbnail, and extract URL/mention entities from the body for related-link surfacing. Five tools, one structured card payload ready for chat embeds, social shares, or RSS-to-card pipelines.
Output
A structured link preview card object containing the page title, description (from og:description or article body fallback), normalized og:image at 1200×630 resolution, and other OpenGraph/Twitter card metadata extracted from the target URL.
Example use cases
Example prompt
“Can you build me a link preview card for https://techcrunch.com/2024/05/15/openai-announces-new-model/ — I need the title, description, and a normalized 1200×630 preview image pulled from its OpenGraph and Twitter card metadata?”
Technical details
Endpoint
POSThttps://agent402.tools/api/skill/link-previewWhen to prefer
Use this endpoint when you need a fully normalized, card-ready link preview (title, description, standardized 1200×630 image) from a single public URL, especially when you want automatic fallback from OpenGraph to article body content and image normalization built in — rather than writing custom scraping logic or calling multiple metadata APIs separately.
Side effects
- URL is not publicly accessible or returns a non-200 status — preview card cannot be generated
- Target page has no OpenGraph or Twitter card tags and no extractable article body — description will be empty
- og:image cannot be fetched or normalized — image field may be missing or null
- Malformed or non-HTTP(S) URL provided — validation error returned
- Target site blocks scrapers or returns CAPTCHA — metadata extraction fails
