​
OpenAI SDK

OpenAI Node.js SDK 可直接使用。

​
安装

npm install openai

​
基础用法

import OpenAI from "openai";

const client = new OpenAI({
  baseURL: "https://api.arouter.ai/v1",
  apiKey: "lr_live_xxxx",
});

const response = await client.chat.completions.create({
  model: "openai/gpt-5.4",
  messages: [{ role: "user", content: "Hello!" }],
});
console.log(response.choices[0].message.content);

​
多 Provider

// 通过 OpenAI SDK 使用 Anthropic
const response = await client.chat.completions.create({
  model: "anthropic/claude-sonnet-4.6",
  messages: [{ role: "user", content: "Hello!" }],
});

// 通过 OpenAI SDK 使用 DeepSeek
const response = await client.chat.completions.create({
  model: "deepseek/deepseek-v3.2",
  messages: [{ role: "user", content: "Hello!" }],
});

​
流式输出

const stream = await client.chat.completions.create({
  model: "openai/gpt-5.4",
  messages: [{ role: "user", content: "写一首诗。" }],
  stream: true,
});

for await (const chunk of stream) {
  const content = chunk.choices[0]?.delta?.content;
  if (content) process.stdout.write(content);
}

​
Anthropic SDK

Anthropic Node.js SDK 可原生使用。

​
安装

npm install @anthropic-ai/sdk

​
基础用法

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

const client = new Anthropic({
  baseURL: "https://api.arouter.ai",
  apiKey: "lr_live_xxxx",
});

const message = await client.messages.create({
  model: "claude-sonnet-4.6",
  max_tokens: 1024,
  messages: [{ role: "user", content: "Hello!" }],
});
console.log(message.content[0].text);

​
流式输出

const stream = client.messages.stream({
  model: "claude-sonnet-4.6",
  max_tokens: 1024,
  messages: [{ role: "user", content: "给我讲个故事。" }],
});

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

​
ARouter SDK

官方 @arouter/sdk 提供 key 管理和用量追踪等额外功能。

​
安装

npm install @arouter/sdk

​
对话补全

import { ARouter } from "@arouter/sdk";

const router = new ARouter({
  apiKey: "lr_live_xxxx",
  baseURL: "https://api.arouter.ai",
});

const response = await router.chatCompletion({
  model: "openai/gpt-5.4",
  messages: [{ role: "user", content: "Hello!" }],
});
console.log(response.choices[0].message.content);

​
流式输出

const stream = await router.chatCompletionStream({
  model: "openai/gpt-5.4",
  messages: [{ role: "user", content: "写一首俳句。" }],
});

for await (const chunk of stream) {
  const content = chunk.choices[0]?.delta?.content;
  if (content) process.stdout.write(content);
}

​
Key 管理

使用管理密钥（lr_mgmt_）创建和管理 API key。 
const mgmt = new ARouter({
  apiKey: "lr_mgmt_xxxx",
  baseURL: "https://api.arouter.ai",
});

const key = await mgmt.createKey({
  name: "backend-service",
  allowed_providers: ["openai", "anthropic"],
  limit: 150,
  limit_reset: "monthly",
});
console.log("API Key:", key.key);

const keys = await mgmt.listKeys();
console.log("Keys:", keys.data);

await mgmt.updateKey(key.data.hash, { disabled: true });

await mgmt.deleteKey(key.data.hash);

​
钱包 JWT + x402 支付

拥有加密钱包的 AI 代理可通过 SIWx 验证身份，并通过 x402 支付积分。 SDK 会缓存钱包 JWT，并将其作为后续请求的 Bearer token。

​
EVM（Base）

import { ARouter, withX402EvmPayment } from "@arouter/sdk";
import { privateKeyToAccount } from "viem/accounts";

const signer = privateKeyToAccount(process.env.EVM_PRIVATE_KEY as `0x${string}`);

const client = withX402EvmPayment(
  new ARouter({ baseURL: "https://api.arouter.ai", apiKey: "" }),
  signer,
);

const response = await client.chatCompletion({
  model: "openai/gpt-5.4",
  messages: [{ role: "user", content: "Hello" }],
});

​
Solana

import { ARouter, withX402SolanaPayment } from "@arouter/sdk";

const client = withX402SolanaPayment(
  new ARouter({ baseURL: "https://api.arouter.ai", apiKey: "" }),
  solanaSigner,
  { address: solanaAddress, signMessage: (msg) => signEd25519(msg) },
);

​
仅 SIWx（不自动支付）

import { ARouter, withSIWxAuth } from "@arouter/sdk";

const client = await withSIWxAuth(
  new ARouter({ baseURL: "https://api.arouter.ai", apiKey: "" }),
  { address: "0xYourAddress", signMessage: (msg) => signer.signMessage({ message: msg }) },
);
完整协议流程请参见 x402 支付指南。
