Cloudflare has introduced an AMP linter API for developers to check the correct formatting of their AMP pages before deployment. The API can be used by sending a webpage's AMP markup to the endpoint https://amp.cloudflare.com/q/. If the page contains invalid AMP syntax, the returned message will specify what is wrong and provide a link to the relevant implementation guide. This tool aims to make it easier for developers to move their webpages and sites to AMP format.
