API Key Setup (Optional)

To access private data via the Codeforces API, you'll need to generate an API key:

1. Go to Codeforces: Visit Codeforces API Settings.
2. Create a New API Key: Provide a name for the key. Codeforces will generate:
   • Key: The public part of the API key.
   • Secret: A private part used for signing requests.
3. Store the Key and Secret:
   • Add your key and secret to a .env file in your project directory:

     key="your_api_key"
     secret="your_api_secret"
