Endpoint
POSThttps://proxy.suverse.io/v1/data/polymarket-price-historyWhen to prefer
Choose this endpoint when you need historical probability or price time series for a Polymarket outcome token and want a simple proxied API with per-call pricing rather than managing direct Polymarket CLOB API access. Ideal for charting, backtesting, or analyzing how market consensus shifted over a defined period.
Side effects
- Invalid or unknown token ID returns an error or empty series
- Unsupported interval value causes a validation error
- Network timeout if upstream Polymarket CLOB is slow
- Payment failure (x402) if USDC balance is insufficient
- Empty result if the token has no trading history at the requested resolution
