Endpoint
GEThttps://prediction-intel-tan.vercel.app/api/historyWhen to prefer
Use this endpoint when you need historical probability or price time-series data for a specific Polymarket prediction market outcome, particularly when building charts, backtesting strategies, or analyzing how market sentiment evolved over time. Prefer this over live/current-price endpoints when trend analysis or historical context is needed.
Side effects

- Unsupported interval value results in a 400 bad request
- Service unavailable if Polymarket CLOB API is down
- Payment failure if insufficient USDC balance on Base for the $0.008 per-call fee
- Very narrow fidelity on a long interval may return too many data points or timeout
