Extract metadata from any website with an API call. The API allows fetching of metatags, open graph data and schema tags.

Built with Elysia + Cheerio with Bun runtime

API

Uses Elysia for managing routing and cheerio to parse the HTML of the page and retrieve meta data.

The server is deployed using Docker on Fly.io. You can use the GET API with the any URL as a query parameter.

Send a request with any URL :

https://getmetadata.fly.dev/v1/meta?url=<insert_url_to_fetch_metadata>

Responds with the metadata, OpenGraph data and used Schema tags

https://getmetadata.fly.dev/v1/meta?url=https://en.wikipedia.org/wiki/Batman

which returns the following JSON.
