API 接入示例

方法一：环境变量（对 AutoGPT、LangChain 等第三方工具最通用）

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

部分旧工具读取的是 OPENAI_API_BASE，两个都设上即可。修改环境变量后需重启终端或程序。

方法二：OpenAI 官方客户端

from openai import OpenAI

client = OpenAI(
    base_url="https://api.crazyrouter.com/v1",
    api_key="sk-xxxx",  # 在 https://crazyrouter.com 控制台「令牌」页创建
)

# 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)

最后校验/修改：2026-09-28（Base URL 改为 api.crazyrouter.com；删除 openai<1.0 的 openai.api_base 旧写法；gpt-4o/gpt-5 → gpt-5.5；示例未实跑）
