The public API for running ComfyUI workflows headlessly
The public API for running ComfyUI headlessly has evolved over time. For new integrations, use Comfy API v2. It is supported on open-source ComfyUI (during the beta, via the API Proxy), Comfy Cloud, and the new Serverless API. Older versions include the v1 Cloud API, which is deprecated.
