How this service works
Get all trades for a specific wallet address across all prediction markets. Trades are decoded from on-chain OrderFilled events on Polygon. **What it helps to answer:** 1. **What trades has this address made on Polymarket?** 2. **When did this trader buy or sell, and at what prices?** 3. **What markets has this address been active in?**
Output
Returns a paginated list of trade records for the given wallet, each containing: trade side (Yes/No), size in tokens, price per share (0-1), USDC value, buyer and seller addresses, transaction hash, market ID, event ID, event title, market question, taker action (buy/sell), outcome index, and ISO timestamp. Also includes pagination metadata (page, per_page, total).
