## Comparing X API’s List lookup endpoints

The v2 List lookup endpoint group will replace the standard v1.1 [GET lists/show](https://developer.x.com/en/docs/twitter-api/v1/accounts-and-users/create-manage-lists/api-reference/get-lists-show) and  [GET lists/ownership](https://developer.x.com/en/docs/twitter-api/v1/accounts-and-users/create-manage-lists/api-reference/get-lists-ownerships) endpoints. If you have code, apps, or tools that use one of these versions of the List lookup endpoints, and are considering migrating to the newer X API v2 endpoint, then this set of guides is for you.

The following tables compare the standard v1.1 and X API v2 List endpoints:
