SiftingIO

About SiftingIO

SiftingIO is a market data API providing real-time and historical price data across six asset classes: US equities, forex, cryptocurrency, commodities, DEX/DeFi, and on-chain data. Data is aggregated and normalized from multiple sources into a single consistent schema, accessible over REST and WebSocket with one credential. Coverage includes US-listed stocks, ETFs, and ADRs with fundamentals and corporate actions; forex majors, minors, and exotics; tick-level crypto data; DEX swap and liquidity pool activity across Ethereum, Base, Arbitrum, Optimism, Polygon, BNB Chain, Avalanche, and Solana; and metals, energy, and agricultural commodity prices.

The service offers official client libraries for Go, Python, and JavaScript, plus integration guides for MetaTrader, n8n, and Supabase. It also provides free tools including a market-hours checker, a symbol catalog, and an embeddable live market-status widget, along with a free tier of the API (REST and WebSocket, no credit card required).

SiftingIO is aimed at developers building applications such as quantitative research tools, fintech products, treasury systems, and dashboards. It also runs an education program offering free or discounted access for academic research, classrooms, and student projects.
