How this service works
Polymarket whale trades and smart-money signals from the Predge tracking pipeline, sold per-call over the x402 payment protocol. No API keys, no accounts.
Output
A JSON object containing a list of individual trades (with fields: wallet, market title, market slug, condition ID, side, entry price, size in USD, resolution, whether the trade won, modeled P&L per trade, running modeled P&L, and 30-day win rate), plus a summary with total trade count, decided trades, wins, overall win rate, and aggregate modeled P&L. Also includes the queried address and window. A note clarifies that modeled_pnl_usd is an estimate, not settled P&L.
Example use cases
Vetting a whale before copying trades
“Before I mirror this trader, can you pull the 30-day Polymarket trade history for wallet 0x8dab6cf42d7e4d1cd6cca897b9e12a8cbe6d69e8? I want to see their win rate, wallet score, and how much they've modeled-profited.”
Long-term whale performance audit
“Give me the all-time Polymarket trade history for wallet 0xabc123…, I want to know their total trades, decided trades, wins, and cumulative modeled P&L across everything they've ever done.”
Monitoring a known smart-money address
“Check the last 90 days of Polymarket activity for this wallet — 0x4f9a12… — and tell me which markets they bet on, what side they took, what price they entered at, and whether they won.”
Technical details
Endpoint
GEThttps://x402-api-production-266e.up.railway.app/v1/wallets/%7Baddress%7D/historyWhen to prefer
Use this endpoint when you need a comprehensive historical view of a single whale wallet's Polymarket activity — including per-trade details, running P&L, and a wallet quality score — rather than a top-level leaderboard or market-wide whale activity. Prefer this over the market-specific whale endpoint when the user is investigating a known wallet address rather than a specific market. Best when you want multi-market aggregated performance across a configurable time window (30d, 90d, or all-time) for one address.
Side effects
- Invalid or non-existent wallet address returns empty trades array or 404
- Unrecognized window value (not 30d/90d/all) may return 400 or default behavior
- Payment not fulfilled via x402 protocol returns 402 Payment Required
- Address with no Polymarket activity returns empty summary and trades list
- Network or Railway infrastructure downtime returns 5xx error
