SiftingIO

What it is

SiftingIO: the homepage

SiftingIO is a market data platform delivering real-time and historical data for multiple asset classes including US equities, foreign exchange, cryptocurrencies, commodities, decentralized finance venues, and on-chain fundamentals. The platform aggregates data from multiple venues and sources, de-duplicating and normalizing it into a consistent JSON schema accessible via REST and WebSocket APIs under a single credential and authentication model.

Developers and financial teams use SiftingIO to build trading systems, broker platforms, dashboards, alerts, research tools, and backtesting workflows without maintaining separate integrations for each asset class. The same production stack, authentication, and data model work across free and enterprise tiers, enabling seamless scaling as usage grows.
