How to use

Please invoke this endpoint with a POST request.

The headers of the request must include an API key in the authorization field. The body of the request must be
multipart/form-data. The accept header should be set to one of the following:

image/* to receive the image in the format specified by the output_format parameter.

application/json to receive the image encoded as base64 in a JSON response.

Generating with a prompt

Commonly referred to as text-to-image, this mode generates an image from text alone. While the only required
parameter is the prompt, it also supports an aspect_ratio parameter which can be used to control the
aspect ratio of the generated image.

**Generating with a prompt and an image**

Commonly referred to as image-to-image, this mode also generates an image from text but uses an existing image as the
starting point. The required parameters are:

prompt - text to generate the image from

image - the image to use as the starting point for the generation

strength - controls how much influence the image parameter has on the output image

mode - must be set to image-to-image

Note: maximum request size is 10MiB.

Optional Parameters:

Both modes support the following optional parameters:

model - the model to use (SD3 Medium, SD3 Large, or SD3 Large Turbo)

output_format - the the format of the output image

seed - the randomness seed to use for the generation

negative_prompt - keywords of what you do not wish to see in the output image

Note: for more details about these parameters please see the request schema below.

Output

The resolution of the generated image will be 1MP. The default resolution is 1024x1024.

Credits

SD3 Medium: Flat rate of 3.5 credits per successful generation.

SD3 Large: Flat rate of 6.5 credits per successful generation.

SD3 Large Turbo: Flat rate of 4 credits per successful generation.

As always, you will not be charged for failed generations.
