Index & Treasury Futures API
Live financial futures as an API — front-month prices for the major US index and Treasury futures, served from Yahoo Finance. For any contract it returns the current price, the previous close, the absolute and percentage change on the day, the day's high and low, the 52-week high and low, the contract month and the currency. Index futures (E-mini S&P 500, Nasdaq-100, Dow, Russell 2000) trade nearly around the clock and are the market's go-to read on where the open is heading; Treasury futures (2-, 5-, 10- and 30-year notes and bonds) track interest-rate expectations. Look a contract up by name or ticker alias, pull a category board (index or rates) ranked by the day's move, or get the whole board in one call. The futures-quote layer for trading, pre-market and dashboard apps. Live, no key, no cache. Distinct from spot index APIs and from the physical-commodity futures API — this is financial (index and rate) futures.
