Project overview
The short version
SiftingIO's US Stocks API is a market data service from SaltingIO LLC. One API key covers live trades and top-of-book quotes over REST or WebSocket, historical OHLCV bars from 1-minute to monthly intervals, company search with CIK and exchange details, SEC filings such as 10-K, 10-Q and 8-K, XBRL financial concepts and ratios, Form 3, 4 and 5 insider transactions, and current 13F holdings. The page lists a median delivery time under 100 ms and 25+ years of history depending on the ticker. A free plan with 10,000 REST calls a month is available for non-commercial testing, and Pro for US stocks is listed at $320 a month. The data is aggregated from third-party sources, not raw exchange feeds.
