API 调用

除了 CLI 工具，你也可以直接通过 HTTP 请求调用 RouterBus API。

API 基础信息

• Base URL: https://routerbus.com
• 认证方式: Bearer Token
• 兼容格式: OpenAI API 格式

Chat Completions

请求示例

curl https://routerbus.com/v1/chat/completions \
  -H "Content-Type: application/json" \
  -H "Authorization: Bearer sk-xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx" \
  -d '{
    "model": "claude-sonnet-4-20250514",
    "messages": [
      {"role": "user", "content": "Hello!"}
    ]
  }'

流式输出

curl https://routerbus.com/v1/chat/completions \
  -H "Content-Type: application/json" \
  -H "Authorization: Bearer sk-xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx" \
  -d '{
    "model": "claude-sonnet-4-20250514",
    "messages": [
      {"role": "user", "content": "Hello!"}
    ],
    "stream": true
  }'

Python SDK

使用 OpenAI Python SDK：

from openai import OpenAI

client = OpenAI(
    api_key="sk-xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx",
    base_url="https://routerbus.com/v1"
)

response = client.chat.completions.create(
    model="claude-sonnet-4-20250514",
    messages=[
        {"role": "user", "content": "Hello!"}
    ]
)

print(response.choices[0].message.content)

Node.js SDK

import OpenAI from 'openai';

const client = new OpenAI({
  apiKey: 'sk-xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx',
  baseURL: 'https://routerbus.com/v1',
});

const response = await client.chat.completions.create({
  model: 'claude-sonnet-4-20250514',
  messages: [{ role: 'user', content: 'Hello!' }],
});

console.log(response.choices[0].message.content);

Claude API 原生格式

如果你需要使用 Claude 的原生 Messages API 格式：

curl https://routerbus.com/v1/messages \
  -H "Content-Type: application/json" \
  -H "x-api-key: sk-xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx" \
  -H "anthropic-version: 2023-06-01" \
  -d '{
    "model": "claude-sonnet-4-20250514",
    "max_tokens": 1024,
    "messages": [
      {"role": "user", "content": "Hello!"}
    ]
  }'

TIP

推荐使用 OpenAI 兼容格式，这样可以方便地切换不同模型而无需修改代码。
