Quick Start - DeerAPI Documentation

30-second switch from OpenAI

Use this two-setting diff when you switch an OpenAI SDK client to DeerAPI:

- base_url="https://api.openai.com/v1"
- api_key=os.environ["OPENAI_API_KEY"]
+ base_url="https://api.deerapi.com/v1"
+ api_key=os.environ["DEERAPI_KEY"]

Make your first call

The following example sends a chat completion request:

curl https://api.deerapi.com/v1/chat/completions \
  -H "Authorization: Bearer $DEERAPI_KEY" \
  -H "Content-Type: application/json" \
  -d '{
    "model": "your-model-id",
    "messages": [
      {"role": "user", "content": "Write a one-sentence product tagline."}
    ]
  }'
