How this service works
Recent trades from any Polymarket market (by slug or conditionId) or for a specific wallet. Returns side, size, price, timestamp, trader pseudonym, on-chain tx hash, and computed notional USD. A data-only Polymarket trade feed for prediction-market and on-chain bet-history research.
Output
A list of recent trade records, each containing: trade side (YES/NO buy or sell), size (shares), price (implied probability), timestamp, trader pseudonym, on-chain transaction hash, and computed notional value in USD.
Example use cases
Monitor a hot prediction market
“Show me the latest trades on the Polymarket market for 'will-the-fed-cut-rates-in-june' — I want to see the prices, trade sizes, and whether people are buying YES or NO.”
Audit a wallet's betting history
“Can you pull all recent Polymarket trades for wallet address 0xABC123...def and show me what bets they've placed, at what prices, and the transaction hashes?”
Track price action by conditionId
“Get me the recent trade feed for Polymarket conditionId 0x7f4e...b2c1 — I need side, price, size, and notional USD for each trade to see how the market has moved.”
Technical details
Endpoint
POSThttps://x402.agentutility.ai/polymarket-tradesWhen to prefer
Use this endpoint when you need granular, trade-level data from Polymarket — including on-chain tx hashes, trader pseudonyms, and notional USD — rather than just market prices or order book snapshots. Ideal for trade history audits, wallet tracking, or feeding a trading analytics pipeline. Prefer over scraping Polymarket's UI or using less structured data sources.
Side effects
- Invalid or unknown market slug returns empty results or error
- Invalid conditionId format causes a 400-level error
- Wallet address with no Polymarket activity returns empty trade list
- Rate limiting or payment failure (insufficient USDC balance) returns 402 or 429
- Polymarket data source unavailable causes timeout or 503
