Crazyrouter SDK 完整使用指南

更新日期：2026-06-23

适用场景

Crazyrouter 对 OpenAI SDK 兼容接口提供统一接入。聊天、Responses API、图片、音频、嵌入和模型列表优先使用官方 OpenAI SDK；视频、Kling、Luma、Suno、Midjourney 等异步或厂商原生接口使用同一个 API Key，通过 fetch 调用 Crazyrouter 原生路径。默认国际 API 入口：

https://api.crazyrouter.com

OpenAI SDK 需要填写带 /v1 的地址：

https://api.crazyrouter.com/v1

不要把 OpenAI SDK 的 baseURL 写成 https://api.crazyrouter.com，否则 SDK 会少拼 /v1。也不要写成 https://api.crazyrouter.com/v1/chat/completions，否则 SDK 会重复拼路径。

安装 SDK

npm install openai

Node.js 建议使用 18 或更高版本。Node.js 18+ 已内置 fetch、FormData 和 Blob。

配置环境变量

macOS / Linux:

export CRAZYROUTER_API_KEY="sk-your-api-key"
export CRAZYROUTER_BASE_URL="https://api.crazyrouter.com"

Windows PowerShell:

$env:CRAZYROUTER_API_KEY = "sk-your-api-key"
$env:CRAZYROUTER_BASE_URL = "https://api.crazyrouter.com"

创建 SDK Client

import OpenAI from 'openai';

const apiKey = process.env.CRAZYROUTER_API_KEY;

if (!apiKey) {
  throw new Error('Missing CRAZYROUTER_API_KEY');
}

const baseURL = process.env.CRAZYROUTER_BASE_URL ?? 'https://api.crazyrouter.com';

export const client = new OpenAI({
  apiKey,
  baseURL: `${baseURL}/v1`,
  timeout: 180_000,
});

Chat Completions

const response = await client.chat.completions.create({
  model: 'gpt-5.5',
  messages: [
    { role: 'system', content: 'You are concise.' },
    { role: 'user', content: 'Say sdk-ok and nothing else.' },
  ],
  max_tokens: 16,
});

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

流式输出

const stream = await client.chat.completions.create({
  model: 'gpt-5.5',
  messages: [{ role: 'user', content: 'Count from 1 to 3.' }],
  max_tokens: 32,
  stream: true,
});

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

模型列表

const models = await client.models.list();

for (const model of models.data.slice(0, 10)) {
  console.log(model.id);
}

Embeddings

const embedding = await client.embeddings.create({
  model: 'text-embedding-3-small',
  input: 'Crazyrouter SDK test',
});

console.log(embedding.data[0].embedding.length);

Responses API

Responses API 适合支持 /v1/responses 的 GPT 系列模型。

const response = await client.responses.create({
  model: 'gpt-5.5',
  input: 'Return only: responses-ok',
  max_output_tokens: 16,
});

console.log(response.output_text);

Claude 模型不要放到 Responses API 路径里测试。Claude 推荐使用 /v1/messages 或 OpenAI-compatible /v1/chat/completions。

图片、音频和转录

OpenAI-compatible 图片和音频接口也使用同一个 SDK client。

const image = await client.images.generate({
  model: 'gpt-image-2',
  prompt: 'A simple white mug on a clean table',
  size: '1024x1024',
  output_format: 'png',
});

console.log(image.data[0]?.url);

const speech = await client.audio.speech.create({
  model: 'tts-1',
  voice: 'alloy',
  input: 'Hello from Crazyrouter.',
});

const audio = Buffer.from(await speech.arrayBuffer());
console.log(audio.length);

原生异步任务接口

视频、Kling、Luma、Suno、Midjourney 等异步任务通常不是 OpenAI SDK 方法，而是 Crazyrouter 原生 HTTP 路径。仍然使用同一个 API Key。

async function crazyrouterFetch<T>(
  path: string,
  options: RequestInit & { json?: Record<string, unknown> } = {},
): Promise<T> {
  const response = await fetch(`${baseURL}${path}`, {
    ...options,
    headers: {
      Authorization: `Bearer ${apiKey}`,
      ...(options.json ? { 'Content-Type': 'application/json' } : {}),
      ...options.headers,
    },
    body: options.json ? JSON.stringify(options.json) : options.body,
  });

  const body = await response.json().catch(() => ({}));
  if (!response.ok) {
    throw new Error(`Crazyrouter API error ${response.status}: ${JSON.stringify(body)}`);
  }

  return body as T;
}

提交统一视频任务：

const task = await crazyrouterFetch<{
  id?: string;
  task_id?: string;
  data?: { task_id?: string };
}>('/v1/video/create', {
  method: 'POST',
  json: {
    model: 'veo-3.1-fast',
    prompt: 'A quiet city street after rain, cinematic lighting',
    aspect_ratio: '16:9',
    size: '1080P',
  },
});

const taskId = task.data?.task_id ?? task.task_id ?? task.id;
console.log(taskId);

查询任务：

const result = await crazyrouterFetch(
  `/v1/video/query?task_id=${encodeURIComponent(taskId!)}`,
);

console.log(result);

上传本地图片

需要把本地参考图传给 image-to-video、vision 或图片编辑接口时，先上传到 Crazyrouter 临时存储。

import { readFile } from 'node:fs/promises';
import { basename } from 'node:path';

async function uploadImage(filePath: string) {
  const bytes = await readFile(filePath);
  const form = new FormData();

  form.append(
    'file',
    new Blob([bytes], { type: 'image/png' }),
    basename(filePath),
  );
  form.append('purpose', 'model_input');

  const response = await fetch(`${baseURL}/v1/files/uploads`, {
    method: 'POST',
    headers: {
      Authorization: `Bearer ${apiKey}`,
    },
    body: form,
  });

  const body = await response.json();
  if (!response.ok) {
    throw new Error(`Upload failed: ${JSON.stringify(body)}`);
  }

  return body as {
    id: string;
    url: string;
    mime_type: string;
    size: number;
    expires_at: string;
  };
}

const uploaded = await uploadImage('./reference.png');
console.log(uploaded.url);

临时上传 URL 默认用于模型输入，不是永久图床。业务长期资产请使用自己的存储。

完整 SDK 测试脚本

保存为 crazyrouter-sdk-smoke.mjs：

import OpenAI from 'openai';

const apiKey = process.env.CRAZYROUTER_API_KEY;
const rootBaseURL = process.env.CRAZYROUTER_BASE_URL ?? 'https://api.crazyrouter.com';

if (!apiKey) {
  throw new Error('Set CRAZYROUTER_API_KEY before running this test.');
}

const client = new OpenAI({
  apiKey,
  baseURL: `${rootBaseURL}/v1`,
  timeout: 180_000,
});

const checks = [];

async function check(name, fn) {
  const started = Date.now();
  try {
    const detail = await fn();
    checks.push({ name, ok: true, ms: Date.now() - started, detail });
    console.log(`ok ${name}: ${detail}`);
  } catch (error) {
    checks.push({ name, ok: false, ms: Date.now() - started, detail: error.message });
    console.error(`fail ${name}: ${error.message}`);
  }
}

await check('models.list', async () => {
  const models = await client.models.list();
  return `${models.data.length} models`;
});

await check('chat.completions.create', async () => {
  const response = await client.chat.completions.create({
    model: 'gpt-5.5',
    messages: [{ role: 'user', content: 'Return exactly sdk-ok' }],
    max_tokens: 16,
  });
  return response.choices[0]?.message?.content?.trim() ?? '(empty)';
});

await check('chat.completions.stream', async () => {
  const stream = await client.chat.completions.create({
    model: 'gpt-5.5',
    messages: [{ role: 'user', content: 'Return exactly stream-ok' }],
    max_tokens: 16,
    stream: true,
  });

  let text = '';
  for await (const chunk of stream) {
    text += chunk.choices[0]?.delta?.content ?? '';
  }
  return text.trim() || '(empty stream)';
});

await check('embeddings.create', async () => {
  const response = await client.embeddings.create({
    model: 'text-embedding-3-small',
    input: 'Crazyrouter SDK smoke test',
  });
  return `${response.data[0].embedding.length} dimensions`;
});

await check('raw /v1/video/query route shape', async () => {
  const response = await fetch(`${rootBaseURL}/v1/video/query?task_id=doc-smoke-test`, {
    method: 'GET',
    headers: {
      Authorization: `Bearer ${apiKey}`,
    },
  });

  const text = await response.text();
  if (response.status === 404 && text.toLowerCase().includes('not found')) {
    throw new Error('route returned a path-level 404');
  }

  return `route reachable, status ${response.status}`;
});

const failed = checks.filter((item) => !item.ok);
console.log(JSON.stringify({ total: checks.length, failed: failed.length, checks }, null, 2));

if (failed.length > 0) {
  process.exit(1);
}

运行：

npm install openai
node crazyrouter-sdk-smoke.mjs

测试通过后，你应至少看到：

models.list 返回模型数量
chat.completions.create 返回文本
chat.completions.stream 收到流式文本
embeddings.create 返回向量维度
/v1/video/query 返回任务不存在或其他业务状态，说明原生异步任务查询路由可达

常见错误

问题	处理方式
`401 Unauthorized`	检查 `CRAZYROUTER_API_KEY` 是否设置，格式是否为 `Authorization: Bearer sk-...`
`404` 或 `/v1/v1/...`	OpenAI SDK 使用 `https://api.crazyrouter.com/v1`，原生 HTTP 使用 `https://api.crazyrouter.com` 加完整路径
Chat 可用但 Responses 不可用	检查模型是否支持 `/v1/responses`，Claude 不要走 Responses API
图片或视频超时	提高 SDK timeout，视频类任务优先使用异步任务查询
403 Forbidden	Token 没有对应模型权限，或模型不在该 token 的可用范围内
