API Schema
List of URLs or local Base64 encoded images to edit.
The size of the generated image.
square_hd
The same seed and the same prompt given to the same version of the model will output the same image every time.
If set to true, the function will wait for the image to be generated and uploaded before returning the response. This will increase the latency of the function but it allows you to get the image directly in the response without going through the CDN.
false
If set to True, the safety checker will be enabled.
true
The text prompt describing the content, style, or composition of the image to be generated.
The number of images to generate.
1

Quick Example
Let's generate an image of the specified size using a simple prompt.
import requests
import json # for getting a structured output with indentation
response = requests.post(
"https://api.aimlapi.com/v1/images/generations",
headers={
# Insert your AIML API Key instead of <YOUR_AIMLAPI_KEY>:
"Authorization":"Bearer <YOUR_AIMLAPI_KEY>",
"Content-Type":"application/json",
},
json={
"model":"bytedance/seedream-v4-edit",
"prompt": "Add a bird to the foreground of the photo.",
"image_urls": [
"https://raw.githubusercontent.com/aimlapi/api-docs/main/reference-files/t-rex.png"
]
}
)
data = response.json()
print(json.dumps(data, indent=2, ensure_ascii=False))


"Add a bird to the foreground of the photo."
