n8n-nodes-useapi

n8n community nodes for useapi.net — a unified REST API for AI video, image, music, and creative services including Midjourney, Dreamina, Kling, Runway, PixVerse, MiniMax, InsightFaceSwap, Google Flow, Mureka, and TemPolor.

Note: The npm package name n8n-nodes-useapi is taken by an unrelated package. Install from GitHub (see below).

API Version Support (v0.6.7+)

Examples

Import ready-to-use workflow templates from the examples/ directory directly into n8n.

Installation

GitHub Install (Recommended)

For self-hosted n8n running in Docker:

docker exec -u node n8n sh -c "
  mkdir -p /home/node/.n8n/nodes &&
  cd /home/node/.n8n/nodes &&
  npm install github:ArielleTolome/n8n-nodes-useapi
"
docker restart n8n

For self-hosted n8n (bare metal):

cd ~/.n8n/nodes
npm install github:ArielleTolome/n8n-nodes-useapi

Restart n8n after installation. The nodes will appear in the node picker — search for UseAPI.

Async Job Handling

Most AI operations are asynchronous. Each creation operation has a Wait for Completion toggle (enabled by default) that automatically polls the job status until it completes or fails.

• Polling interval: 3 seconds
• Timeout: 5 minutes (300 seconds)
• On failure: Throws an error with the failure message

Disable Wait for Completion to get the initial job response immediately, then use the corresponding Get Job/Task operation to check status manually.

For immediate fire-and-forget without polling, use the Async toggle (where supported) — returns the task ID only.

Note: Create GIF and Concatenate Videos (Google Flow) are synchronous and do not require polling.

Example: Midjourney Imagine

1. Add the UseAPI node to your workflow
2. Select Midjourney as the resource
3. Select Imagine as the operation
4. Enter your prompt (optionally add sref/cref for style/character references)
5. Execute — the node waits for the image to be generated and returns the full result with image URLs

Rate Limits

The useapi.net API enforces rate limits per account/plan. When the limit is exceeded, the API returns HTTP 429 or 402 (quota exceeded).

Recommendations for high-volume workflows:

• Disable Wait for Completion and poll manually to avoid holding long-running requests.
• Add a Wait node between batches to control request cadence.
• Check your plan limits at useapi.net.
