I'm working with the API for several weeks (see my app [here][1]) and I'm trying to get the username of a particular user from its Stack Exchange ID.

It's possible by querying [/users/{ids}][2] but it returns data from one website at a time, so it will require more requests to get data from multiple users if theirs accounts belong to different websites.

Example:

 1. [Get the websites associated to my Account ID][3] and store a website and its `user_id`
 2. [Get the badges associated to my `user_id`][4] (you may need to associate `site_URL` with `api_site_parameter`)

See how the `network_user` node is present in every badge.

If a global method (returning data from the Stack Exchange network) was available, it should require less requests since it would only take user ids and return only one note per user.

Am I missing something?

If this data is not available, is it possible to add a simple `/users/{ids}` which returns global data and not on a per-site basis?

Examples:

 - Account #1 on Stack Overflow (ok): http://api.stackexchange.com/2.1/users/1?site=stackoverflow
 - Account #1 on Stack Exchange (the method does not exist): http://api.stackexchange.com/2.1/users/1
