Stable Diffusion API Docs

๐Ÿ‘‹ Welcome

The Stable Diffusion V3 API comes with these features:

  • Faster speed;
  • Inpainting;
  • Image 2 Image;
  • Negative Prompts.

The Stable Diffusion API is organized around REST. Our API has predictable resource-oriented URLs, accepts form-encoded request bodies, returns JSON-encoded responses, and uses standard HTTP response codes, authentication, and verbs.


We have chatbot trained on docs and codebase, click on footer chat icon and ask question, it will give you code examples as well :)

The Stable Diffusion API is equipped with a NSFW checker. Any image detected as NSFW will be replaced by a blank image.


Be aware of the content of your images. We have a filter system to remove any child pornography. Multiple attempts will result in account suspension.

The Stable Diffusion API uses keys to authenticate the requests. Pass the key you've obtained from the API Settings page to the request body and follow all the endpoint processes accordingly.

Send JSON POST requests with data and links.


Do not send files as raw format, send publicly accessible links to them instead.

Here you will find information about the Stable Diffusion and Multiple AI APIs.

You can pass details to generate images using this API, without the need of GPU locally.

All API requests are authorized by a key. You can obtain one by signing up.

  1. Use 100+ models to generate images with single API call.
  2. Use multi lora models
  3. Use embeddings models
  4. Use controlnet models
  5. Use multi controlnet models
  6. Upscale images
  7. Highres fix
  8. Multiple language support
  9. Self Attention process
  10. Train model
  11. Clipfix
  12. Base64 support

All API requests require a header to be passed. Make sure you pass Content-Type: application/json in the header as shown in the example below:
