Control

This service offers an ideal solution for design projects that require brainstorming and
frequent iterations. It upgrades rough hand-drawn sketches to refined outputs with precise
control. For non-sketch images, it allows detailed manipulation of the final appearance by
leveraging the contour lines and edges within the image.

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, and 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.

The body of the request should include:

image

prompt

The body may optionally include:

control_strength

negative_prompt

seed

output_format

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

Output

The resolution of the generated image will match that of the input image.

Credits

Flat rate of 3 credits per successful generation. You will not be charged for failed generations.

Request

Header Params

authorization

string

required

Your Stability API key, used to authenticate your requests. Although you may have multiple keys in your account, you should use the same key for all requests to this API.

>= 1 characters

content-type

string

required

The content type of the request body. Do not manually specify this header; your HTTP client library will automatically include the appropriate boundary parameter.

>= 1 characters

Example:

multipart/form-data

enum<string>

required

Specify image/* to get the image bytes directly. Otherwise specify application/json to receive the image as base64 encoded JSON.

Allowed values:

image/*application/json

Default:

image/*

stability-client-id

string

optional

The name of your application, used to help us communicate app-specific debugging or moderation issues to you.

<= 256 characters

Example:

my-awesome-app

stability-client-user-id

string

optional

A unique identifier for your end user. Used to help us communicate user-specific debugging or moderation issues to you. Feel free to obfuscate this value to protect user privacy.

<= 256 characters

Example:

DiscordUser#9999

stability-client-version

string

optional

The version of your application, used to help us communicate version-specific debugging or moderation issues to you.

<= 256 characters

Example:

1.2.1

Body Params multipart/form-data

prompt

string

required

What you wish to see in the output image. A strong, descriptive prompt that clearly defines
elements, colors, and subjects will lead to better results.

To control the weight of a given word use the format (word:weight),
where word is the word you'd like to control the weight of and weight
is a value between 0 and 1. For example: The sky was a crisp (blue:0.3) and (green:0.8)
would convey a sky that was blue and green, but more green than blue.
