polycopy
polycopy lets you follow traders, copy trades from a feed, read Copy Score and track your portfolio through its free tier. Copy Score uses finished trades and subtracts copying costs to estimate what following a trader would have left, assuming each trade was copied exactly. Premium adds Auto Copy Bots, including Strategy Bots and Trader Bots, plus Fire Feed. Trades on both tiers carry a flat 0.5% trading fee.
polywhaler
polywhaler tracks large trades on Polymarket and Kalshi, with a whale feed, watchlists, wallet profiles and interactive market charts for examining activity. Each trade gets a score based on size, odds, timing and market context. Pro adds custom Discord and Telegram alerts, whale history and CSV/JSON export, while Premium adds advanced alert filters. Orca supports backtesting whale copying, paper portfolios and placing live orders on both markets.
Polymarket documentation
Polymarket documentation explains how to fetch market data, place orders and redeem winning positions, with a developer quickstart for making an initial API request. Its platform introductions cover how markets and trading work before you choose an integration approach. The SDKs and APIs material covers programmatic integration with Polymarket. Start with the quickstart for a first request, then consult the core concepts material as you implement market and trading workflows.
Polymarket data API
Polymarket data API returns wallet trades and reconstructed P&L, and recomputes top monthly leaderboard wallets daily by reconciling public trades against resolutions to include resolved losses. Start with /leaderboard/true-pnl, then inspect a wallet through /wallets/{id}/trades and /wallets/{id}/pnl. It also returns market history, resolutions and order books as JSON. Coverage stops at up to 10,500 fills per wallet, and reconstructed P&L uses the newest continuous trade window, not an audited lifetime or monthly balance.
How to choose and limits
Choose by the task you need to complete, whether that means copying a trader, watching large trades, placing orders or inspecting wallet P&L. For reconstructed returns, check the reported coverage before using a number to decide whether to follow a wallet. Missing opening inventory and unobserved activity can limit the result, especially for active wallets with short recent windows. The resolved market archive grows as outcomes are discovered, and order book subscriptions record while the service runs. Past wallet performance is not a recommendation.
