API Integration Examples

Method 1: Environment variables (most universal for third-party tools such as AutoGPT and LangChain)

OPENAI_BASE_URL=https://api.crazyrouter.com/v1
OPENAI_API_KEY=sk-xxxxx

Some older tools read OPENAI_API_BASE instead; just set both. Restart your terminal or program after changing environment variables.

Method 2: Official OpenAI client

from openai import OpenAI

client = OpenAI(
    base_url="https://api.crazyrouter.com/v1",
    api_key="sk-xxxx",  # Create one on the "Tokens" page of the https://crazyrouter.com console
)

# Chat Completions
response = client.chat.completions.create(
    model="gpt-5.5",
    messages=[
        {"role": "system", "content": "You are a helpful assistant."},
        {"role": "user", "content": "Who won the world series in 2020?"},
        {"role": "assistant", "content": "The Los Angeles Dodgers won the World Series in 2020."},
        {"role": "user", "content": "Where was it played?"},
    ],
)
print(response.choices[0].message.content)

# Responses API
response = client.responses.create(
    model="gpt-5.5",
    input="Write a one-sentence bedtime story about a unicorn.",
)
print(response.output_text)
