ComfyUI Integration

Integrate NextAPI video generation into your ComfyUI node-based workflows. Use our custom node or the generic HTTP request node to add Seedance video generation to any pipeline.

Configuration

Set the following values in your ComfyUI configuration:

python

# ComfyUI Custom Node: NextAPI Video Generate
# Place in ComfyUI/custom_nodes/nextapi_node.py

import os
import requests

class NextAPIVideoGenerate:
    @classmethod
    def INPUT_TYPES(cls):
        return {
            "required": {
                "prompt": ("STRING", {"multiline": True}),
                "duration_seconds": ("INT", {"default": 6, "min": 1, "max": 30}),
                "resolution": (["720p", "1080p", "4k"],),
            }
        }

    RETURN_TYPES = ("STRING",)
    RETURN_NAMES = ("video_url",)
    FUNCTION = "generate"
    CATEGORY = "NextAPI"

    def generate(self, prompt, duration_seconds, resolution):
        resp = requests.post(
            "https://api.nextapi.top/v1/video/generations",
            headers={
                "Authorization": f"Bearer {os.environ.get('NEXTAPI_KEY', '')}",
                "Content-Type": "application/json",
            },
            json={
                "model": "seedance-2.0-pro",
                "prompt": prompt,
                "duration_seconds": duration_seconds,
                "resolution": resolution,
            },
        )
        resp.raise_for_status()
        data = resp.json()
        return (data.get("url", ""),)

NODE_CLASS_MAPPINGS = {"NextAPIVideoGenerate": NextAPIVideoGenerate}
NODE_DISPLAY_NAME_MAPPINGS = {"NextAPIVideoGenerate": "NextAPI Video Generate"}

Setup Steps

1Copy the custom node file to ComfyUI/custom_nodes/nextapi_node.py.
2Set your API key as an environment variable: export NEXTAPI_KEY=your-key-here
3Restart ComfyUI to load the new node.
4Find "NextAPI Video Generate" in the node browser under the "NextAPI" category.
5Connect a text input to the prompt field and wire the video_url output to your pipeline.
6Execute the workflow — the node will call NextAPI and return the generated video URL.

Test with cURL

Verify your setup by running this command:

bash

curl -X POST https://api.nextapi.top/v1/video/generations \
  -H "Authorization: Bearer $NEXTAPI_KEY" \
  -H "Content-Type: application/json" \
  -d '{
    "model": "seedance-2.0-pro",
    "prompt": "ink spreading through water in slow motion",
    "duration_seconds": 6,
    "resolution": "1080p"
  }'
