I'm wondering if there is a simple way of using the API to find users given their e-mail address. So far, I've found the following:

This is not supported, intentionally. Email addresses are private information, only exposed to employees and moderators of Stack Exchange.

If you want to identify a user using your application, you should use the authentication flow.

  • I totally understand and respect that. Though in my case, I already know the e-mail address. What I want to know is some information about the user with this address, more specifically her reputation and badges. In case you wonder why - I'd like to create a Stackoveflow raplet in order to show the user's activity using rapportive, which is a tool that shows information about a user in e-mail applications (currently used in gmail).
