Introduction

Claude is an AI chat service provided by Ace Data Cloud, based on the Anthropic Claude series large language models. Through the unified API of Ace Data Cloud, you can quickly integrate Claude using Python to achieve multi-turn conversations, system prompts, streaming output, JSON output mode, and other features.

​
Prerequisites

  • Have an Ace Data Cloud account and obtain an API Token
  • Python 3.7 or above environment
  • Install the requests library: pip install requests

​
Basic Usage

The main endpoint to call the Claude API is: 
POST https://api.acedata.cloud/v1/chat/completions
This example uses the claude-sonnet-4-6 model.
Available models include: claude-sonnet-4-6, claude-opus-4-5-20251101, claude-3-5-sonnet. Complete Python code example: 
import requests

url = "https://api.acedata.cloud/v1/chat/completions"
headers = {
    "Authorization": "Bearer YOUR_API_TOKEN",
    "Content-Type": "application/json"
}
data = {
    "model": "claude-sonnet-4-6",
    "messages": [
        {
            "role": "user",
            "content": "你好，请介绍一下你自己"
        }
    ],
    "max_tokens": 1024,
    "temperature": 0.7
}

response = requests.post(url, headers=headers, json=data)
result = response.json()
print(result)
Please replace YOUR_API_TOKEN with the actual Token you obtained from the Ace Data Cloud platform.

​
Response Handling

After a successful call, the API returns data in JSON format. It is recommended to check the HTTP status code: 
if response.status_code == 200:
    result = response.json()
    print("Call succeeded:", result)
else:
    print(f"Call failed, status code: {response.status_code}")
    print(response.text)

​
Advanced Usage

For chat APIs, streaming output is supported to get real-time responses: 
import requests

data['stream'] = True
response = requests.post(url, headers=headers, json=data, stream=True)
for line in response.iter_lines():
    if line:
        print(line.decode())

​
Error Handling

Common error codes:
