Introduction

Kimi is an AI chat service provided by Ace Data Cloud, featuring the Kimi series large language models from the dark side of the moon. Through the unified API of Ace Data Cloud, you can quickly integrate Kimi using JavaScript to achieve multi-turn conversations, system prompts, streaming output, JSON output mode, and more.

​
Prerequisites

  • Have an Ace Data Cloud account and obtain an API Token
  • Node.js 18+ or a modern browser environment

​
Basic Usage

The main endpoint for calling the Kimi API is: 
POST https://api.acedata.cloud/kimi/chat/completions
This example uses the kimi-k2.5 model.
Available models include: kimi-k2.5, kimi-k2-thinking-turbo, kimi-k2-thinking, kimi-k2-instruct-0905. Complete JavaScript code example: 
const response = await fetch("https://api.acedata.cloud/kimi/chat/completions", {
  method: "POST",
  headers: {
    "Authorization": "Bearer YOUR_API_TOKEN",
    "Content-Type": "application/json",
  },
  body: JSON.stringify({
  "model": "kimi-k2.5",
  "messages": [
    {
      "role": "user",
      "content": "你好，请介绍一下你自己"
    }
  ],
  "max_tokens": 1024,
  "temperature": 0.7
}),
});

const result = await response.json();
console.log(result);
Please replace YOUR_API_TOKEN with the actual token you obtained from the Ace Data Cloud platform.

​
Response Handling

It is recommended to check the response status code and handle errors: 
if (response.ok) {
  const result = await response.json();
  console.log("Call succeeded:", result);
} else {
  console.error(`Call failed, status code: ${response.status}`);
  const error = await response.text();
  console.error(error);
}

​
Node.js Wrapper

It is recommended to encapsulate it as a reusable function: 
async function callKimi(data) {
  const response = await fetch("https://api.acedata.cloud/kimi/chat/completions", {
    method: "POST",
    headers: {
      "Authorization": `Bearer ${process.env.ACE_API_TOKEN}`,
      "Content-Type": "application/json",
    },
    body: JSON.stringify(data),
  });
  if (!response.ok) throw new Error(`API error: ${response.status}`);
  return response.json();
}
