Real-time and historical financial market data APIs for developers.
What is Polygon.io?
Polygon.io is a financial data platform founded in 2016 by a team focused on democratizing access to real-time and historical market data. The company’s technical architecture is built around robust APIs that aggregate, normalize, and deliver vast datasets from global exchanges, rather than being centered on a single predictive AI model. Its key capabilities include providing real-time stock, forex, and crypto tick data, extensive historical pricing, and fundamental company data. The platform is engineered for developers, quantitative analysts, and fintech companies who require reliable data feeds to build trading algorithms, conduct backtesting, power financial applications, or perform in-depth market research. By offering streamlined API access, Polygon.io integrates directly into automated workflows, eliminating the need for costly and complex data infrastructure. This allows businesses to focus resources on strategy and development, significantly accelerating time-to-market for data-driven financial products.
