API

The source code is well documented. I tried to make it as simple as possible and followed the same conventions as the official API. You can simply hover over the method name to see the description of the method and its parameters.

You can find function defentions and types in src/types.ts

Authorization

The only method that requires authorization is user.friends. To authorize your requests you need to set your API_KEY and API_SECRET using the setCredentials method.

You can get your API key from http://codeforces.com/settings/api.

Return Data

Data is returned in JSON format. For full description of data format visit http://codeforces.com/apiHelp/objects.
