Create new endpoints for GraphQL

这个 Issue 没有描述。

The issue only says to create new GraphQL endpoints and names no files, schema, queries, mutations, or expected behavior. It is also very old and already has assignees, so a newcomer should not start coding from this issue without maintainer confirmation and a concrete endpoint specification. Done cannot be determined from the payload alone.
