Anthropic SDK 配置指南

Anthropic 官方 SDK 支持通过 base_url 参数替换 API 端点。

端点说明

Anthropic SDK 会自动在 baseURL 后追加 /v1，因此填写：

https://llm.starapp.net/api/llm

Python

安装

pip install anthropic

代码示例

import anthropic

client = anthropic.Anthropic(
    base_url="https://llm.starapp.net/api/llm",
    api_key="your-token-here",
)

message = client.messages.create(
    model="claude-sonnet-4-5",
    max_tokens=1024,
    messages=[
        {"role": "user", "content": "Hello, Claude!"}
    ]
)
print(message.content[0].text)

流式输出

with client.messages.stream(
    model="claude-sonnet-4-5",
    max_tokens=1024,
    messages=[{"role": "user", "content": "写一首诗"}],
) as stream:
    for text in stream.text_stream:
        print(text, end="", flush=True)

环境变量方式

export ANTHROPIC_BASE_URL=https://llm.starapp.net/api/llm
export ANTHROPIC_AUTH_KEY=your-token-here

import anthropic

# 自动从环境变量读取
client = anthropic.Anthropic()

Node.js / TypeScript

安装

npm install @anthropic-ai/sdk
# 或
yarn add @anthropic-ai/sdk

代码示例

import Anthropic from "@anthropic-ai/sdk";

const client = new Anthropic({
  baseURL: "https://llm.starapp.net/api/llm",
  apiKey: "your-token-here",
});

const message = await client.messages.create({
  model: "claude-sonnet-4-5",
  max_tokens: 1024,
  messages: [
    { role: "user", content: "Hello, Claude!" }
  ],
});
console.log(message.content[0].text);

流式输出

const stream = client.messages.stream({
  model: "claude-sonnet-4-5",
  max_tokens: 1024,
  messages: [{ role: "user", content: "写一首诗" }],
});

for await (const event of stream) {
  if (event.type === "content_block_delta" && event.delta.type === "text_delta") {
    process.stdout.write(event.delta.text);
  }
}

cURL 测试

curl https://llm.starapp.net/api/llm/v1/messages \
  -H "Content-Type: application/json" \
  -H "x-api-key: your-token-here" \
  -H "anthropic-version: 2023-06-01" \
  -d '{
    "model": "claude-sonnet-4-5",
    "max_tokens": 1024,
    "messages": [
      {"role": "user", "content": "Hello!"}
    ]
  }'

注意事项

• api_key 填入您的 Inkess Token（ik-...）
• 可用模型 ID 见模型列表
• Anthropic SDK 的 base_url 无需追加 /v1
