AI Agent Support
Both nodes set usableAsTool: true, making them available as tools in n8n's AI Agent node. Build workflows where an LLM:
- Searches for markets related to a topic
- Checks current prices and spreads
- Places trades based on analysis
This is the first trading node in the n8n ecosystem with AI agent support.
Workflow Templates
5 demand-backed templates built on what Polymarket traders actually use and pay for:
- Smart Money Radar -- Track top traders from the Polymarket leaderboard, monitor their trades in real-time, and get whale alerts on Telegram. Based on the #1 paid tool category in the Polymarket ecosystem.
- AI News-to-Market Matcher -- RSS feed triggers AI analysis matched to Polymarket markets. When news breaks, find the affected market, check the price, and get a directional signal. The workflow that made Betmoar dominant.
- Mispricing Scanner -- Scan for logically inconsistent pricing across correlated markets. When exclusive outcomes don't sum to 100%, you've found a mispricing.
- Daily Portfolio Digest -- Morning summary of your wallet positions with P&L breakdown. The most underserved category in Polymarket tooling.
- Resolution Watcher -- Monitor markets approaching resolution. Get alerts when your markets are about to close. A genuinely unserved niche.
Credentials
Market and Price operations work without credentials (public API endpoints).
Trading operations require Polymarket CLOB API credentials:
- Go to polymarket.com/settings
- Generate CLOB API credentials (Key, Secret, Passphrase)
- In n8n, create Polymarket API credentials with your key, secret, passphrase, and wallet private key
FAQ
How do I automate Polymarket trading?
Install this node in n8n, set up your Polymarket API credentials, and use the Place Order operation. Orders are cryptographically signed with EIP-712 and submitted to Polymarket's CLOB.
Can I use this with n8n's AI Agent?
Yes. Both nodes support usableAsTool. Connect them to an AI Agent node and the LLM can search markets, check prices, and place orders.
Does this work with n8n Cloud?
Yes. Go to Settings > Community Nodes > Install and search for n8n-nodes-polymarket-tools. Works on any n8n instance (self-hosted or Cloud).
How is this different from the other Polymarket node?
The existing n8n-nodes-polymarket (v4.2.0) cannot place trades -- all trading operations throw "Coming Soon" errors. This node implements full EIP-712 order signing via viem and @polymarket/clob-client.
