通过 POST https://www.bettertoken.ai/v1/chat/completions 调用 OpenAI-compatible Chat Completions。外部工具通常只填写 Base URL https://www.bettertoken.ai/v1，由工具自行追加 /chat/completions。

重点信息

字段	填写内容
API Key	BetterToken API Key
完整请求 URL	`https://www.bettertoken.ai/v1/chat/completions`
Model	`YOUR_MODEL_ID`

准备工作

创建 BetterToken API Key
从模型广场或 Console 中对应 Key 的 Setup 弹窗复制 Model ID
准备支持 curl 的终端，或 Python 3 / Node.js

安装

curl
Python
JavaScript

curl 无需额外 SDK。确认终端可以运行 curl --version。

python -m pip install openai

npm install openai

手动配置

curl

curl "https://www.bettertoken.ai/v1/chat/completions" \
  -H "Authorization: Bearer YOUR_API_KEY" \
  -H "Content-Type: application/json" \
  --data '{
    "model": "YOUR_MODEL_ID",
    "messages": [
      {
        "role": "user",
        "content": "Hello"
      }
    ]
  }'

Python SDK

from openai import OpenAI

client = OpenAI(
    api_key="YOUR_API_KEY",
    base_url="https://www.bettertoken.ai/v1",
)

response = client.chat.completions.create(
    model="YOUR_MODEL_ID",
    messages=[
        {"role": "user", "content": "Hello"},
    ],
)

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

JavaScript SDK

import OpenAI from "openai";

const client = new OpenAI({
  apiKey: "YOUR_API_KEY",
  baseURL: "https://www.bettertoken.ai/v1",
});

const response = await client.chat.completions.create({
  model: "YOUR_MODEL_ID",
  messages: [{ role: "user", content: "Hello" }],
});

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

验证连接

在右侧 Playground 中：

在 Authorization 中输入 YOUR_API_KEY。
将 model 替换为 YOUR_MODEL_ID。
修改 messages 后发送请求。

Playground 使用完整路径 https://www.bettertoken.ai/v1/chat/completions，无需手动拼接 endpoint。收到 200 响应且 choices[0].message.content 包含模型回复，即表示连接成功。

切换模型

把请求中的 YOUR_MODEL_ID 替换为模型广场或 Setup 弹窗中的完整 Model ID。不要根据展示名称自行缩写 Model ID。

常见错误

错误	处理方式
`401`	检查 `Authorization` 是否为 `Bearer YOUR_API_KEY`，并重新复制 BetterToken API Key。
`404`	直接调用使用完整 URL `https://www.bettertoken.ai/v1/chat/completions`；SDK 的 `base_url` 使用 `https://www.bettertoken.ai/v1`。
模型不存在	使用模型广场或 Setup 弹窗中的完整 Model ID。
请求格式错误	确认 `messages` 是数组，并且每项包含 `role` 和 `content`。

进阶配置

支持的提供商

提供商	状态
Claude	暂不支持
GPT	手动配置
Kimi	手动配置
GLM	手动配置

状态仅针对本页介绍的 BetterToken 接入方式。

配置方式说明

手动配置：填写 API Key、Base URL 和 Model。
不支持：当前没有经过验证的直接配置方式。

技术说明

Base URL 与完整请求 URL

GitHub Copilot 和 TRAE 等要求完整请求 URL 的工具使用 https://www.bettertoken.ai/v1/chat/completions。Cursor、Cline、OpenCode、n8n 和 Dify 等会自行追加路径的工具只填写 https://www.bettertoken.ai/v1。
