ReActor Extension API

Built-in SD WebUI API | External ReActor API

---

Gourieff's ReActor SD WebUI Extension allows to operate via API: both built-in and external (POST and GET requests).

Built-in SD WebUI API

This API is actual if you use Automatic1111 stable-diffusion-webui.

First of all - check the SD Web API Wiki for how to use the API.

• Call requests.get(url=f'{address}/sdapi/v1/script-info') to find the args that ReActor needs;
• Define ReActor script args and add like this "alwayson_scripts": {"reactor":{"args":args}} in the payload;
• Call the API.

You can find the full usage example with all the available parameters and discriptions in the "example" folder.

External ReActor API

ReActor extension supports for external calls via POST or GET requests while your SD WebUI server is working.

:warning: Source and Target images must be "base64".

Example:

curl -X POST \
    'http://127.0.0.1:7860/reactor/image' \
    -H 'accept: application/json' \
    -H 'Content-Type: application/json' \
    -d '{
    "source_image": "data:image/png;base64,/9j/4QAYRXhpZgAASUkqAAgAAAAAAAAAAAAAAP/sABFEdWNreQABAAQAAABQAAD/7g...",
    "target_image": "data:image/png;base64,/9j/4QAYRXhpZgAASUkqAAgAAAAAAAAAAAAAAP/sABFEdWNreQABAAQAAABCAAD/7g...",
    "source_faces_index": [0],
    "face_index": [0],
    "upscaler": "4x_Struzan_300000",
    "scale": 2,
    "upscale_visibility": 1,
    "face_restorer": "CodeFormer",
    "restorer_visibility": 1,
    "restore_first": 1,
    "model": "inswapper_128.onnx",
    "gender_source": 0,
    "gender_target": 0,
    "save_to_file": 0,
    "result_file_path": ""
    }'

• Set "upscaler" to "None" and "scale" to 1 if you don't need to upscale;
• Set "save_to_file" to 1 if you need to save result to a file;
• "result_file_path" is set to the "outputs/api" folder by default (please, create the folder beforehand to avoid any errors) with a timestamped filename; (output_YYYY-MM-DD_hh-mm-ss), you can set any specific path, e.g. "C:/stable-diffusion-webui/outputs/api/output.png".

You can find full usage examples with all the available parameters in the "example" folder: cURL, JSON.

As a result you recieve a "base64" image:

{"image":"iVBORw0KGgoAAAANSUhEUgAABlAAAARQCAIAAAAdiYuqAAEAAElEQVR4nOz9+ZMlSXImBn6qau4vIjKzzr5wzwBCDrm/7f+/K7IHV3ZkhUIuyZHlkBhiMGig0Y0..."}
