+<Update label="Aug 26, 2026" description="X API v2">
+  ### Bot accounts for the Chat API
+
+  Today, we added [bot endpoints](/xchat/bots) to the Chat API. Bots are programmatic X accounts owned by your project, authenticated with a bearer token instead of a login, and labeled "Automated by @owner".
+
+  Six new `/2/bots` endpoints let you:
+
+  - [Create a bot](/x-api/bots/create-a-bot) and [list your project's bots](/x-api/bots/get-bots)
+  - [Update a bot's identity](/x-api/bots/update-bot) (handle, display name, DM permissions) and [delete a bot](/x-api/bots/delete-bot)
+  - [Rotate](/x-api/bots/rotate-bot-token) or [revoke](/x-api/bots/revoke-bot-token) a bot's bearer token
+
+  All six endpoints use OAuth 2.0 app-only authentication. See the [Bots guide](/xchat/bots) to get started.
