Automate your outgoing webmentions

31,665 webmentions delivered so far.

This is a platform agnostic service that will check a given URL for links to other sites, discover if they support webmentions, then send a webmention to the target.

The notification API is reasonably simplistic:

  • POST https://webmention.app/check/?url=:url

    Finds all links in your given URL, discovers those with valid Webmention endpoints, and sends the full webmention notifications.

    The URL should be escaped (though the protocol is not required), and an optional token can be used to avoid the rate limit.

  • GET https://webmention.app/check/?url=:url
    Perform a dry run, reporting on all discovered Webmention endpoints
