SiftingIO

SiftingIO provides real-time and historical market data for developers building financial applications. The platform covers US stocks and ETFs, forex, commodities and crypto through REST APIs and WebSocket streaming. It is designed for teams that need current prices for an application alongside historical data for research and analysis.

For US stocks, available historical coverage reaches 25+ years. The service includes ETFs as well as individual shares, so a developer can work with both in a market dashboard or research workflow. Forex history also reaches 25+ years, while commodities coverage extends to 20+ years and crypto coverage to 10+ years. These figures describe available dataset depth; the start date and fields depend on the instrument and dataset selected.

The REST API supports applications that request data when it is needed. WebSocket streaming supports applications that receive ongoing real-time updates. Python, TypeScript and Go SDKs provide language-specific ways to integrate the service. Public documentation explains the available endpoints and request fields, giving a team a concrete starting point for testing an integration.

Historical OHLCV bars can be used for price charts, time-series research and backtesting. A useful evaluation starts with a small set of instruments and a defined time range, then checks that the returned data suits the application's requirements. Teams can compare available intervals and fields in the documentation before building a larger data workflow.

SiftingIO also offers a browser-based market data export tool for people who want to analyse selected data in a spreadsheet. CSV and Excel downloads provide a route from the API-backed tool into a workbook, without requiring a custom application for that task.

A free plan is available for developers evaluating the platform, with paid subscriptions for broader usage requirements. SiftingIO is operated by SaltingIO LLC. It serves developers, research teams and financial software builders who need one place to work with several asset classes.
