USOS API Browser is a simple interactive OAuth client for Windows, designed for browsing and testing USOS API methods.
Note: The list of available methods is dynamically fetched from the chosen USOS API server. The screenshot may be outdated.
This application is for testing purposes only. It was written as a quick
example of basic USOS API usage. There are tons of WebExceptions it doesn't
even try to catch!
Having that said, I still think that it is quite useful developer tool, especially if you're aiming for a deep understanding on how the USOS API OAuth authorization actually works.
You can use this deployment site. Please note, that it can be a little ahead or behind the master branch.
