Endpoint

When to prefer

Use this endpoint when you need historical OHLCV price chart data for a specific Polymarket outcome token at a particular time resolution (5s, 1m, 5m, 15m, 1h, 4h, 1d). Prefer it over trade-level endpoints when you want aggregated candlestick data rather than raw individual trades, and over other prediction market data sources when you need on-chain Polymarket data paid via x402/USDC micropayment.

Side effects

token_id not found on Polymarket returns an empty klines array
