As we evolve the Twitter API, we will be releasing v2 API endpoints incrementally -- giving developers access to new endpoints as they’re ready.
Early Access endpoints are fully supported and different from the endpoints available in Twitter Developer Labs. These endpoints are fully supported and ready for you to use in production. The first live endpoints are now available, and can be used for free at the new Basic level, with an approved developer account.
As we move through this Early Access stage, we will maintain our standard v1.1, premium, and enterprise endpoints until the v2 API is fully ready to replace the current endpoints.
