The first n8n node with full prediction market trading. EIP-712 signed orders, whale tracking, AI agent support, and 15 workflow templates. Free and open source.
polymarket-tools is an open-source n8n community node that connects n8n workflow automation to Polymarket's full API surface. It wraps three Polymarket APIs: the Gamma API for market discovery and search, the CLOB API for real-time pricing and EIP-712 signed order placement, and the Data API for leaderboard rankings, wallet positions, trade history, and market holder analysis.
Every read operation works without credentials. Polymarket's Data API is fully public: any trader's positions, trades, and P&L are queryable with just a wallet address. The leaderboard ranks every trader by profit. This transparency makes Polymarket uniquely suited for automated analysis, whale tracking, and signal generation.
Trading operations handle EIP-712 typed data signatures via a viem WalletClient. The node manages the full order lifecycle: build, sign, submit, track, cancel. Limit orders support GTC, GTD, FOK, and FAK time-in-force. A validate-only mode enables paper trading without risk.
Both nodes set usableAsTool, making them available as tools inside n8n's AI Agent node. This enables autonomous agents that search markets, analyze prices, track whale wallets, and execute trades based on AI reasoning.
15 workflow templates ship with the node. Each template is a complete, importable n8n workflow built from real demand in the Polymarket trading ecosystem: whale trade alerts, copy trading, sportsbook edge detection, AI news-to-market matching, tax report generation, market making, BTC momentum scalping, portfolio tracking, election polling divergence, and more.
The node is free, MIT licensed, and published to npm as n8n-nodes-polymarket-tools. Install it in any n8n instance (self-hosted or Cloud) via Settings > Community Nodes.

Yes. Both nodes set usableAsTool, making them available as tools in n8n's AI Agent node. Build autonomous agents that search markets, analyze prices, track whale wallets, and execute trades. The AI Agent Polymarket Trader template demonstrates this end-to-end.

n8n-nodes-polymarket-tools wraps the full Polymarket API surface: Gamma API for market discovery, CLOB API for pricing and trading, and Data API for leaderboard and wallet data. It is the most complete Polymarket integration available for any workflow automation platform.
With n8n-nodes-polymarket-tools you can build: copy trading bots, whale tracking agents, sportsbook edge scanners, AI news-to-market matchers, market making bots, BTC momentum scalpers, portfolio trackers, tax report generators, mispricing scanners, election polling monitors, and resolution watchers. 15 templates are included covering all of these.
Yes. Polymarket enforces rate limits via Cloudflare throttling. Gamma API (market search): 4,000 req/10s. CLOB API (pricing, trading): 9,000 req/10s for reads, 3,500/10s for order placement. Data API (wallets, leaderboard): 1,000 req/10s general, 200/10s for trades, 150/10s for positions. Polling triggers at 1-5 minute intervals stay well under all limits. The node handles 429 responses by extracting the Retry-After header and surfacing it in the error message. Rule of thumb: poll every 1-5 minutes for most workflows, 30 seconds only for single-market price monitoring.
