How to use Command A in your app

The quickest way is through an API gateway such as OpenRouter, which uses the same format as the OpenAI API. Create a key, then send a request with the model ID cohere/command-a:

curl https://openrouter.ai/api/v1/chat/completions \ -H "Authorization: Bearer $OPENROUTER_API_KEY" \ -H "Content-Type: application/json" \ -d '{ "model": "cohere/command-a", "messages": [{"role": "user", "content": "Explain this in simple words..."}] }'
