lora: String, optional id of the LoRA model. You can query /models to get the full list of LoRA lora_scale: Float, optional, default = 0.75 | | Extra input for img2img | init_image_file: a file object, the base image, required for img2img

image_strength: Float, optional How much to transform the base image, default = 0.75

controlnet: String, optional ControlNet to use, legit values are canny, depth and openpose Note when controlnet is set, image_strength will have no effect

see one example of how to make img2img request | | Output | Success: { error_code: 0, images=[ ‘image url’, ‘image url’, …] , credit_cost: 2.2, inf_id: 'xxxxxxxxxxxxxx' }

Failure: { error_code: 1, message: “This is an error message” } |

Model ID

You can call /models to get the complete model list, including LoRAs. The id of each model can be found in the returned json.

You can also go to sinkin.ai, enter a model page and the last part of the url is the model id. E.g. for the model at https://sinkin.ai/m/vlDnKP6, the model id is vlDnKP6.

    params = {

        'steps': 30,

        'height': 768,
        # 'image_strength': 0.75,
        # 'controlnet': 'openpose'
    }

    files = {'init_image_file': open('path-to-image-file', 'rb')}
    
    r = requests.post('<https://sinkin.ai/api/inference>', files=files, data=params)

    print(r.text)
