SiftingIO

About

SiftingIO provides developers with a unified API for accessing both live and historical data covering US equities, foreign exchange, cryptocurrencies, commodities, and on-chain markets. With consistent schemas across REST, WebSocket, SDKs, and MCP, teams can progress from a rapid prototype to full production without having to reconstruct their data infrastructure. We aim to make dependable market data more accessible and practical to use for independent developers and larger teams alike.
