ComfyUI KIE API Nodes

Project overview

A set of ComfyUI custom nodes that connect to the Kie.ai API for image and video generation workflows.

Why this exists

ComfyUI users often need consistent, API-backed nodes that map directly to model capabilities and work reliably in production workflows. This pack focuses on clear inputs, predictable outputs, and practical integration.

What’s included

• Image generation nodes
• Image-to-video and text-to-video nodes
• Utility helpers for grid slicing and prompt parsing

Node-specific documentation is available in web/docs.

Available Nodes

This node pack currently includes the following nodes:

Generation Nodes

• NanoBanana Image

  • Image generation node using the Googles Nano Banana Pro model via the Kie.ai API.

• Seedream Text-to-Image / Edit

  • Text-to-image and image-editing node for Seedream models.
  • Supports prompt-based generation and edits.

• Kling 2.6 Image-to-Video

  • Generates video from a single input image.
  • Uses the Kling 2.6 image-to-video model.

• Kling 2.6 Motion-Control Image-to-Video

  • Image-to-video generation with additional motion control parameters.
  • Designed for more directed camera and motion behavior.

• Kling 2.6 Text-to-Video

  • Generates video directly from a text prompt.
  • Supports aspect ratio, duration, and sound options as exposed by the API.

Utility / Helper Nodes

• GridSlice

  • Splits a grid image (such as 2×2 or 3×3) into individual images for downstream processing.

• Prompt Grid JSON Parser

  • Parses structured JSON output (for example, from an LLM) into individual prompt outputs.
  • Designed for multi-image and storyboard-style workflows.

Each node has its own documentation page under web/docs/ with detailed inputs, outputs, and usage examples.
