Properties

• [Required] msg.OPENAI_API_KEY: This is the API key provided by OpenAI. It is necessary for authentication when making requests to the OpenAI API.

1. When msg.type is set to create_image:

   • [Required] msg.prompt: A text description of the desired image(s). The maximum length is 1000 characters.

   • msg.n: The number of images to generate. Must be between 1 and 10.

   • msg.size: The size of the generated images. Must be one of 256x256, 512x512, or 1024x1024.

   • msg.response_format: The format in which the generated images are returned. Must be one of url or b64_json.

   • msg.user: A unique identifier representing your end-user, which can help OpenAI to monitor and detect abuse. Learn more

2. When msg.type is set to create_image_edit:

   • [Required] msg.image: The image to edit. Must be a valid PNG file, less than 4MB, and square. If mask is not provided, image must have transparency, which will be used as the mask. For example:

    msg.image = {
        "value": msg.req.files[0].buffer,
        "options": {
            "filename": msg.req.files[0].originalname
        }
    };

   • msg.mask: An additional image whose fully transparent areas (e.g. where alpha is zero) indicate where image should be edited. Must be a valid PNG file, less than 4MB, and have the same dimensions as image. For example

    msg.mask = {
        "value": msg.req.files[1].buffer,
        "options": {
            "filename": msg.req.files[1].originalname
        }
    };

   • [Required] msg.prompt: A text description of the desired image(s). The maximum length is 1000 characters.

   • msg.n: The number of images to generate. Must be between 1 and 10.

   • msg.size: The size of the generated images. Must be one of 256x256, 512x512, or 1024x1024.

   • msg.response_format: The format in which the generated images are returned. Must be one of url or b64_json.

   • msg.user: A unique identifier representing your end-user, which can help OpenAI to monitor and detect abuse. Learn more

3. When msg.type is set to create_image_variation:

   • [Required] msg.image: The image to use as the basis for the variation(s). Must be a valid PNG file, less than 4MB, and square. For example

    msg.image = {
        "value": msg.req.files[0].buffer,
        "options": {
            "filename": msg.req.files[0].originalname
        }
    };

   • msg.n: The number of images to generate. Must be between 1 and 10.

   • msg.size: The size of the generated images. Must be one of 256x256, 512x512, or 1024x1024.

   • msg.response_format: The format in which the generated images are returned. Must be one of url or b64_json.
