30-second switch from OpenAI

Use this two-setting diff when you switch an OpenAI SDK client to CometAPI: 
- base_url="https://api.openai.com/v1"
- api_key=os.environ["OPENAI_API_KEY"]
+ base_url="https://api.cometapi.com/v1"
+ api_key="<COMETAPI_KEY>"
CometAPI uses OpenAI-compatible request formats for common text, image, audio, and video workflows. If your app already uses the OpenAI SDK, start by changing the base URL and API key.

​
Get your API key

To create your CometAPI API key, follow these steps:
  1. Open the CometAPI dashboard.
  2. In the dashboard, open the API key page.
  3. Click Add Token.
  4. Copy the API key and store it in your app or local environment.
For local testing, export your API key as an environment variable: 
export COMETAPI_KEY="<COMETAPI_KEY>"

​
Base URL

Use this base URL for OpenAI-compatible SDKs and API calls: 
https://api.cometapi.com/v1

​
Make your first call

Replace your-model-id with a current model ID from the Models page. 
curl https://api.cometapi.com/v1/chat/completions \
  -H "Authorization: Bearer <COMETAPI_KEY>" \
  -H "Content-Type: application/json" \
  -d '{
    "model": "your-model-id",
    "messages": [
      {
        "role": "user",
        "content": "Write a one-sentence bedtime story."
      }
    ]
  }'
