The SiftingIO US Stocks Market Data API supplies current price observations and historical data for supported US-listed stocks, ETFs and ADRs. It is designed for teams building charting applications, research tools and portfolio dashboards.

Historical OHLCV bars are available over REST at documented intervals from one minute to one month. Supported datasets include more than 25 years of history, with the available period depending on the security and dataset. UTC timestamps and cursor-based pagination help developers load historical series into their own analysis workflows.

For current prices, applications can request REST snapshots or subscribe to live WebSocket updates. A typical implementation can load chart history first, then keep the interface current through the stream. The data can sit alongside the customer's existing portfolio records and analytics.

The product also provides company discovery and profiles, SEC filings, reported XBRL financials, insider transactions and institutional holdings through dedicated endpoints. These datasets allow research teams to bring issuer information and price analysis into the same application.

Public documentation and SDKs provide integration examples. Teams can begin with a free API account, check the securities they need and evaluate responses before selecting a commercial plan. Customer-facing display and other business uses are governed by the applicable plan and licensing terms.
