Fooocus-API

FastAPI powered API for Fooocus.

Currently loaded Fooocus version: 2.1.852.

Run with Replicate

Now you can use Fooocus-API by Replicate, the model is on konieshadow/fooocus-api.

With preset:

• konieshadow/fooocus-api-anime
• konieshadow/fooocus-api-realistic

I believe this is the easiest way to generate image with Fooocus's power.

Reuse model files from Fooocus

You can simple copy config.txt file from your local Fooocus folder to Fooocus-API's root folder. See Customization for details.

Start app

Need python version >= 3.10, or use conda to create a new env.

conda env create -f environment.yaml
conda activate fooocus-api

Run

python main.py

On default, server is listening on 'http://127.0.0.1:8888'

Since v0.3.25, added CMD flags support of Fooocus. You can pass any argument which Fooocus supported.

For example, to startup image generation (need more vRAM):

python main.py --all-in-fp16 --always-gpu

For Fooocus CMD flags, see here.

Start with docker

Before use docker with GPU, you should install NVIDIA Container Toolkit first.

Run

docker run --gpus=all -e NVIDIA_DRIVER_CAPABILITIES=compute,utility -e NVIDIA_VISIBLE_DEVICES=all -p 8888:8888 konieshadow/fooocus-api

For a more complex usage:

mkdir ~/repositories
mkdir -p ~/.cache/pip

docker run --gpus=all -e NVIDIA_DRIVER_CAPABILITIES=compute,utility -e NVIDIA_VISIBLE_DEVICES=all \
    -v ~/repositories:/app/repositories \
    -v ~/.cache/pip:/root/.cache/pip \
    -p 8888:8888 konieshadow/fooocus-api

It will persistent the dependent repositories and pip cache.

You can add -e PIP_INDEX_URL={pypi-mirror-url} to docker run command to change pip index url.

Test API

You can open the Swagger Document in "http://127.0.0.1:8888/docs", then click "Try it out" to send a request.

Completed Apis

Swagger openapi defination see openapi.json.

You can import it in Swagger-UI editor.

All the generation api support for response in PNG bytes directly when request's 'Accept' header is 'image/png'.

All the generation api support async process by pass parameter async_process to true. And then use query job api to retrieve progress and generation results.

Break changes from v0.3.26

• The job_id field from Query Job and Query Job Queue Info apis change type to str. It's an uuid now, which will avoid conflict between each startup.

Break changes from v0.3.25

• Removed cli argument disable-private-log. You can use Fooocus's --disable-image-log for the same purpose.

Break changes from v0.3.24:

• This version merged Fooocus v2.1.839, which include a seed breaking change. Details for 2.1.839.

Break changes from v0.3.16:

• Parameter format for loras has changed for the img2img apis (the multipart/form-data requests). Now it requires JSON string.

Break changes from v0.3.0:

• The generation apis won't return base64 field unless request parameters set require_base64 to true.
• The generation apis return a url field where the generated image can be requested via a static file url.

Break changes from v0.3.21:

• The seed field from generation result change to type String to avoid numerical overflow.
