Check whether a Polymarket market has resolved
Queries Polymarket’s Gamma API for a market’s resolution state and reports whether positions on it are redeemable. Accepts either a 0x… condition id or a numeric Gamma market id.
Note the path has no /exchanges prefix — it sits at the service root.
Auth. Authentication only — this endpoint enforces no scope and no per-provider access check. It requires auth purely to prevent anonymous scraping of Polymarket data through Kairos.
