How this service works
Link-preview metadata of a web page: title, description, Open Graph and Twitter card image, site name, author, publish date, language, canonical URL, favicon and RSS feeds. Use to build link previews, enrich bookmarks or classify a URL without reading the full page.
Output
Returns structured metadata for the given URL including: page title, meta description, Open Graph image URL, Twitter card image, site name, author name, publish date, detected language, canonical URL, favicon URL, and any RSS feed URLs found on the page.
Example use cases
Bookmark enrichment for a reading list
“I just saved a bunch of articles to my reading list — can you fetch the title, description, thumbnail image, author, and publish date for https://www.wired.com/story/ai-future-2024 so I can display a proper preview card?”
Social share preview validation
“Before I post this link on our company Slack, can you check what title, description, and image will appear in the preview when someone shares https://openai.com/blog/chatgpt?”
RSS feed discovery for a website
“Can you grab the metadata for https://www.nytimes.com and tell me if they have an RSS feed I can subscribe to, along with the site name and favicon?”
Technical details
Endpoint
GEThttps://bess-x402.onrender.com/v1/web/metadata?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need fast, structured link-preview metadata (OG tags, title, description, image, favicon, RSS) for a single URL without downloading or parsing the full page content yourself. Ideal for building bookmark enrichment pipelines, social share preview validation, or URL classification workflows. Prefer this over a general web scraper when you specifically need social/meta tag data rather than full page text.
Side effects
- URL is unreachable or returns a non-200 status — metadata may be empty or partial
- Page blocks crawlers (robots.txt or bot detection) — returns limited or no metadata
- Page has no Open Graph or meta tags — title and description may be missing
- Paywalled content may return only preview metadata
- Invalid or malformed URL input causes request failure
- Slow-loading pages may time out before metadata is fully extracted
