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' }

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.

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

    files = {'init_image_file': open('path-to-image-file', 'rb')}
