SiftingIO - One API for real-time and historical market data

by•
SiftingIO gives developers one API for live and historical data across US stocks, forex, crypto, commodities and on-chain markets. REST, WebSocket, SDKs and MCP share consistent schemas, so teams can move from a quick prototype to production without rebuilding their data layer. Our goal is to make reliable market data easier to access and practical to use, whether you are an independent developer or part of a larger team.

Hi Product Hunt, I’m Alper, founder of SiftingIO. I started SiftingIO because getting reliable market data into a product was often more complicated and expensive than it needed to be. We are building one consistent API across stocks, forex, crypto, commodities and on-chain markets, with REST, WebSocket, SDKs and MCP support. Our goal is simple: make high-quality market data easier to access and easier to build with for independent developers and growing teams alike. I would be glad to hear what you are building and where we can make the experience better.
