ComfyUI API

A headless WebSocket-based interface for programmatically executing complex Stable Diffusion workflows as reproducible JSON graphs.

ComfyUI API transforms visual node-based workflows into production-ready endpoints via a local WebSocket server (port 8188 by default). By sending a structured JSON payload to the /prompt endpoint, developers can trigger precise diffusion pipelines including SDXL, ControlNet, and IP-Adapter. This architecture bypasses the standard web UI to enable high-throughput image generation, automated batch processing, and seamless integration into external Python or JavaScript applications. It is the industry standard for scaling generative AI art pipelines without the overhead of a manual interface.
