modelundefined · enumRequiredPossible values:

modestring · enumRequiredPossible values:

image_urlstring · uriRequired

The URL of the reference image.

strengthnumber · min: 0.01 · max: 1Optional

Defines the overall intensity of the sharpening effect. Increases details. Too much sharpening can create an unrealistic result.

minor_denoisenumber · min: 0.01 · max: 1Optional

Removes noisy pixels to increase clarity. Can slightly increase image sharpness.

output_formatstring · enumOptional

The format of the generated image.

Default: jpegPossible values:

subject_detectionstring · enumOptional

Specifies which subjects to detect and process. Options: 'All' (detect all subjects), 'Foreground' (detect only foreground subjects), 'Background' (detect background subjects).

Default: AllPossible values:

face_enhancementbooleanOptional

Whether to enhance faces in the image. When true, the model applies face-specific improvements.

Default: true

face_enhancement_creativitynumber · max: 1Optional

Level of creativity for face enhancement (0-1). Higher values allow more creative, less conservative changes.

Default: 0

face_enhancement_strengthnumber · max: 1Optional

How sharp enhanced faces are relative to background (0-1). Lower values blend changes subtly; higher values make faces more pronounced.

Default: 0.8

Quick Example

Let's sharpen a relatively strongly blurred image using the Strong mode while adjusting the strength parameter.

Python

import requests
import json

def main():
    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": "topaz-labs/sharpen",
          "image_url": "https://raw.githubusercontent.com/aimlapi/api-docs/main/reference-files/blurred-landscape.png",
          "mode": "Strong",
          "strength": 0.9,
          "minor_denoise": 0.9,
          "output_format": "png",
        }
    )

    data = response.json()
    print(json.dumps(data, indent=2, ensure_ascii=False))

if __name__ == "__main__":
    main()
