Provides unified API access to real-time and historical market data across stocks, forex, crypto, and commodities.

SiftingIO is a market data API provider that aggregates real-time and historical pricing across stocks, forex, crypto, and commodities into unified schemas. Founded in the early 2020s, the company targets developers and quantitative teams needing multi-asset coverage without stitching together disparate feeds. Its core offering normalizes data from multiple liquidity venues and exchanges, providing REST and WebSocket access with sub-100ms median latency and 99.9% uptime.

The platform distinguishes itself by offering consistent JSON formatting across asset classes, reducing integration overhead for clients trading cross-asset strategies. While the company has not disclosed funding rounds or revenue, its freemium model—with paid tiers scaling by data volume and asset classes—suggests a focus on developer adoption before enterprise sales. Recent emphasis on crypto and on-chain data reflects demand from algorithmic traders and Web3 projects. The lack of public enterprise client logos raises questions about traction beyond early adopters, though the technical documentation indicates usage by some proprietary trading firms.
