FAQ

Link preview API questions

What is a link preview API?

A link preview API fetches a URL and returns structured metadata your product can use to render a rich preview. Metarabbit handles the page request, metadata extraction, normalization, and caching for you.

Which URL metadata does Metarabbit extract?

Metarabbit extracts page titles, descriptions, favicons, Open Graph tags, and X/Twitter Card fields, then returns them in one consistent JSON response.

Can the API generate a URL summary?

Yes. Add summary=true to a metadata request to include an optional AI summary in the same response, or use the dedicated summary endpoint.

Does Metarabbit cache results?

Yes. Public page metadata is cached for 24 hours, reducing repeat fetch time and load on the source site while keeping integrations predictable.
