The Google AMP Cache is a cache of validated AMP documents published to the web that is available for anyone to use. Google products, including Google Search, serve valid AMP documents and their resources from the cache to provide a fast user experience across the mobile web.

Use the update-cache request to update and remove content from the Google AMP Cache.

To take advantage of the Google AMP Cache, an AMP URL must be accessed directly from the cache using the AMP Cache URL format.

Use the AMP URL API to match URLs to corresponding AMP URLs, and serve the AMP versions instead.
