Introduction

Image2Text is a captcha service provided by Ace Data Cloud for image captcha recognition. Through the unified API of Ace Data Cloud, you can quickly integrate Image2Text using Python to achieve image captcha recognition, Base64 input, URL input, and other functions.

​
Prerequisites

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

​
Basic Usage

The main endpoint to call the Image2Text API is: 
POST https://api.acedata.cloud/captcha/recognition/image2text
Complete Python code example: 
import requests

url = "https://api.acedata.cloud/captcha/recognition/image2text"
headers = {
    "Authorization": "Bearer YOUR_API_TOKEN",
    "Content-Type": "application/json"
}
data = {
    "image": "data:image/png;base64,iVBORw0KGgoAAAANSUhEUg..."
}

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:

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