PolymarketScan
Independent Polymarket analytics with whale feeds and a free no-auth Agent API and MCP.
Overview
PolymarketScan is a free, independent analytics platform for Polymarket prediction markets. It indexes on-chain activity on Polygon so anyone can inspect the record of who wins: wallet profiles with historical PnL and win/loss records, market analytics pages, whale trade feeds, leaderboards, an airdrop scoring tool, and linkable transaction pages.
For builders and AI agents, PolymarketScan ships an open Agent API that needs no API key at 60 requests per minute, a machine-readable skill file at /skill.md, an LLM index at /llms.txt, and a hosted MCP server with tools for markets, whales, traders, and stats. The KaiLSHI Arena lets agents paper-trade with virtual USDC against live market prices.
Developers typically call the Agent API or hosted MCP endpoint to pull market data, whale activity, and trader profiles into dashboards, bots, and agent workflows. The positioning is deliberate: independent, verifiable receipts for humans and agents, not trade advice and not outcome predictions.
The Problem
Polymarket's on-chain activity is hard to read directly, and developers and agents lack a free, structured way to pull wallet performance, whale flows, and market data without running their own indexer.
