it has come to my attention that the includeHasMedia search parameter for the users endpoint is undocumented, so here is the psa that you can use api.wasteof.money/users/jeffalo?includeHasMedia in order to include whether or not the user has set an avatar/banner in the result
( get ) /users/{ username }
Returns an object with information about a user
( get ) /users/{ username }/posts
Returns an Object with an array of 15 of the user's most recent posts
( get ) /posts/{ postId }
