This document will introduce a Face Age Change API integration guide, which can change the age of a face in an image by inputting a picture and an age. The general usage is that users upload a face image, and based on face editing and generation algorithms, an image of the face appearing older or younger is output, supporting changes in the face’s age.

​
Application Process

To use the API, you need to first apply for the corresponding service on the Face Age Change API page. After entering the page, click the “Acquire” button, as shown in the image below: If you are not logged in or registered, you will be automatically redirected to the login page inviting you to register and log in. After logging in or registering, you will be automatically returned to the current page. Upon the first application, there will be a free quota provided, allowing you to use the API for free.

​
Basic Usage

First, understand the basic usage method, which is to input the image link and age information to obtain the processed result image. You need to simply pass an image_url field, with the face image shown below:

Next, we also need to upload the face age information parameter age_infos, which is an array, allowing us to pass multiple pieces of information. We can then fill in the corresponding content on the interface, as shown in the image below:

Here we can see that we have set the Request Headers, including:
  • accept: the format of the response result you want to receive, filled in as application/json, which is JSON format.
  • authorization: the key to call the API, which can be directly selected after application.
Additionally, we set the Request Body, including:
  • image_url: the link to the face image that needs to be processed.
  • age_infos: information about the face’s age and region, where age is a required parameter.
After selection, you can find that the corresponding code is also generated on the right side, as shown in the image below:

Click the “Try” button to conduct a test, as shown in the image above, and we obtained the following result: 
{
  "image_url": "https://faceeffect-1254418846.cos.ap-guangzhou.myqcloud.com/ft/ChangeAgePic/1256437459/bfce1ab8-5fd7-464d-8878-b38433f84d0e"
}
As you can see, the returned result contains an image_url field, which is the face image after the age change based on the input. The changed face information is shown below:

It can be seen that the face in the image has changed according to the input age. Additionally, if you want to generate the corresponding integration code, you can directly copy it, for example, the CURL code is as follows: 
curl -X POST 'https://api.acedata.cloud/face/change-age' \
-H 'accept: application/json' \
-H 'authorization: Bearer {token}' \
-H 'content-type: application/json' \
-d '{
  "age_infos": [{"age":60}],
  "image_url": "https://cdn.acedata.cloud/f5687u.png"
}'
The Python integration code is as follows: 
import requests

url = "https://api.acedata.cloud/face/change-age"

headers = {
    "accept": "application/json",
    "authorization": "Bearer {token}",
    "content-type": "application/json"
}

payload = {
    "age_infos": [{"age":60}],
    "image_url": "https://cdn.acedata.cloud/f5687u.png"
}

response = requests.post(url, json=payload, headers=headers)
print(response.text)

​
Error Handling

When calling the API, if an error occurs, the API will return the corresponding error code and message. For example:
  • 400 token_mismatched: Bad request, possibly due to missing or invalid parameters.
  • 400 api_not_implemented: Bad request, possibly due to missing or invalid parameters.
  • 401 invalid_token: Unauthorized, invalid or missing authorization token.
  • 429 too_many_requests: Too many requests, you have exceeded the rate limit.
  • 500 api_error: Internal server error, something went wrong on the server.

​
Error Response Example

{
  "success": false,
  "error": {
    "code": "api_error",
    "message": "fetch failed"
  },
  "trace_id": "2cf86e86-22a4-46e1-ac2f-032c0f2a4e89"
}
