Installation

Community Nodes (Recommended)

1. Go to Settings > Community Nodes in your n8n instance
2. Click Install
3. Enter n8n-nodes-pollinations
4. Click Install

Manual Installation

Navigate to your n8n installation directory and run:

npm install n8n-nodes-pollinations

For Docker-based installations:

docker exec -it n8n npm install n8n-nodes-pollinations

Then restart your n8n instance.

Configuration

API Key (Optional)

While Pollinations.ai works without authentication, you can obtain a free API key for higher rate limits:

1. Visit enter.pollinations.ai
2. Sign in with GitHub
3. Create an API key
4. Add it to your n8n credentials:
   • Go to Credentials > Add Credential
   • Select Pollinations API
   • Enter your API key

Note: Without an API key, you're limited to one request every 15 seconds. With an API key, you get much higher limits.
