Get prices for every open PredictIt prediction market API

One call returns every open PredictIt market (about 220 on 2026-10-22: House, Senate and governor races, control of Congress, the presidency, world events). One item in the answer is a market with its contracts; each contract carries the last trade price and the best price to buy or sell Yes and No, in dollars per $1 share, so 0.92 means a 92% implied chance. There is no paging: the whole list comes in one answer. Prices move about once a minute and the gateway caches the answer for 60 seconds.

1 live route on PredictIt, from $0.00 per call. Every route below answered our last live test on 2026-11-02; the gateway re-tests them daily.
