The final settlement price for one Polymarket US market, once it has resolved.
Tool description as the model sees it
Settlement (resolution) result for one Polymarket US market by slug — the final settlement price, which is 1 for the winning side / 0 for the losing side on a binary market (and can be a fractional value for a 50/50 or partial settlement). Three distinguishable outcomes: a settled market returns settled: true with the price; an open market that exists but has not resolved returns settled: false with no price and a “still open” message; a slug that does not exist on Polymarket US returns error: "not_found" with settled: null — it is NEVER reported as “still open”. Use after polymarket_us_search / a known slug to check how a market actually resolved. NOTE: this tool returns a price only, no settlement timestamp — Polymarket US does not publish one on this endpoint.
Parameters
| Name | Type | Required | Description |
|---|---|---|---|
slug | string | yes | Polymarket US market slug, from polymarket_us_search. |
