Introduction

Flux is an AI image service provided by Ace Data Cloud, powered by the Black Forest Labs Flux image generation model. Through the unified API of Ace Data Cloud, you can quickly integrate Flux using Python to achieve text-to-image generation, image editing, multiple models, custom sizes, and more.

​
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 for calling the Flux API is: 
POST https://api.acedata.cloud/flux/images
This example uses the flux-pro-1.1 model.
Available models include: flux-dev, flux-pro, flux-pro-1.1, flux-pro-1.1-ultra, flux-kontext-pro, flux-kontext-max. Complete Python code example: 
import requests

url = "https://api.acedata.cloud/flux/images"
headers = {
    "Authorization": "Bearer YOUR_API_TOKEN",
    "Content-Type": "application/json"
}
data = {
    "action": "generate",
    "prompt": "A white siamese cat sitting on a windowsill",
    "model": "flux-pro-1.1",
    "size": "1024x1024"
}

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 APIs that support asynchronous tasks, you can get results via a callback URL: 
data['callback_url'] = 'https://your-server.com/callback'
response = requests.post(url, headers=headers, json=data)
# The result will be pushed to your server via the callback URL

​
Error Handling

Common error codes:
Status CodeDescription
401Authentication failed, please check API Token
403Insufficient balance or no access rights
429Request rate limit exceeded
500Internal server error
