Manual Installation

1. Go to Settings > Community Nodes
2. Select Install
3. Enter n8n-nodes-pollinations-v2 in Enter npm package name
4. Agree to the risks and select Install

Credentials

To use this node, you'll need a Pollinations API key:

1. Visit enter.pollinations.ai
2. Sign up or log in
3. Create a Secret Key (sk_) - Required for n8n server-side use
4. Add the API key to your n8n credentials

API Key Types

Pollinations offers two types of API keys:

• Secret Keys (sk_) ⭐ Recommended for n8n

  • Server-side only, no rate limits
  • Keep secret - never expose publicly
  • Perfect for n8n workflows

• Publishable Keys (pk_) ⚠️ Not recommended for n8n

  • Beta - not ready for production
  • IP rate-limited (1 pollen per IP per hour)
  • For client-side apps only
  • Will consume your Pollen if exposed in public code

Important: Always use Secret Keys (sk_) in n8n for unlimited, server-side access.
