How this service works
Link preview extractor: fetches any URL and returns its title, description, Open Graph and Twitter Card images, favicon, canonical URL and dominant meta tags — the data needed to render a rich preview card. Query params: url (required).
Output
Returns structured metadata extracted from the target webpage including: page title, meta description, Open Graph title/description/image URL, Twitter Card image, favicon URL, canonical URL, and dominant meta tags — everything needed to render a rich link preview card.
Example use cases
Rich preview card in chat app
“Grab the Open Graph title, description, and preview image for this article link https://techcrunch.com/2024/05/01/ai-agents-rise/ so I can display a nice preview card when someone shares it in our chat.”
Social post link enrichment
“Before I schedule this LinkedIn post, fetch the OG metadata for https://www.wired.com/story/best-laptops-2024/ so I can confirm the title and thumbnail that will appear when the link unfurls.”
Bookmark manager metadata
“I just saved https://paulgraham.com/greatwork.html to my reading list — can you pull the page title, description, and favicon so I can display them alongside the bookmark?”
Technical details
Endpoint
GEThttps://failure.zo.space/api/x402/og?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need to quickly render a rich link preview card (title, description, OG image, favicon) for any arbitrary URL without setting up your own scraping infrastructure. It is ideal for chat applications, bookmark managers, social post schedulers, or any product that needs to unfurl links into visual previews. At $0.0003 per call it is cost-effective for on-demand single-URL lookups.
Side effects
- URL is unreachable or returns a non-200 status — metadata may be empty or partial
- Target page has no Open Graph tags — fields may be null or fall back to basic HTML meta
- URL parameter is missing — request rejected with an error
- Target site blocks bots/scrapers — returns empty or error response
- Malformed URL provided — parsing failure returned
- Very slow target sites may cause timeout errors
