Documentation
CrowdIntel is the edge terminal for Polymarket, plus the API underneath it. One data spine — a full on-chain reconstruction of every fill — behind three doors: trade it, build on it, or research it.
These docs cover all three. If you are here to write code, the quickstart gets you from no account to a live API response in about five minutes.
Three ways in
Trade
Advanced traders
Find the traders who actually win — ranked on EV-per-dollar lower bounds, event-clustered z-scores and FDR q-values, never on raw win rate. Reverse-engineer them in a dossier, then follow them with floors you set.
Open the screenerBuild
Bot and agent developers
41 REST endpoints on a free key: screener, wallets, signals, clusters, trades, markets, candles, TWAP settlement, backtests and webhooks. An MCP server points Claude or Cursor at the same data.

Quants and journalists
A full on-chain reconstruction behind investigations, funding-cluster forensics and research dossiers — with the methodology and its caveats written down rather than implied.
