Polymarket data for analysts and builders
Get trader grades, settled P&L, large trades, sharp-money flow, and resolved positions by REST, MCP, or JSON export, from the backend the site runs on. We read Polymarket and place no orders. Live access needs a Pro or Max key, and an export is a snapshot, not a feed.

3 ways to get the data
The same provider-backed data by REST, MCP, or export. Live access needs a Pro or Max plan.
- REST API
Query the data by REST
Trader grades, large trades, profitable wallets' positions, the leaderboard, and suspicious-trade flags over REST, from the same data the site runs on, with an OpenAPI spec and llms-full.txt.
Open - MCP server
Ask from your AI client
One HTTP MCP URL with read-only tools. Connect Claude, Cursor, or any MCP client and pull trader grades, large trades, picks, and reports.
Open - JSON exports
Download a finished dataset
One JSON file per trader: labeled trades, resolved P&L, per-market positions, risk metrics, and category performance, already computed. A point-in-time snapshot, not a feed.

What the data covers
Every field is computed from on-chain fills and the official Polymarket APIs, never parsed from a market title.
- Trader grades: cohort-relative grade (S to F), realized and open P&L, win rate, strategy, category edge
- Large trades: large fills with a review score and the wallet behind each one
- Sharp-money flow and suspicious-trade flags per market and per wallet
- Leaderboard, positions feed, and daily, weekly, and monthly report snapshots
- Polymarket only: no other venue is covered, and there is no order book history
