About IEX Cloud
IEX Cloud offers a comprehensive suite of global financial data, originating from the Investors Exchange (IEX) and over 350 other sources. The platform provides access to real-time and historical equity prices, fundamentals, corporate actions, mutual fund data, forex, and cryptocurrency information. Designed for developers, it features a RESTful API, server-sent events (SSE) for streaming data, and official client libraries in popular programming languages. Its core differentiators are its connection to the IEX exchange, known for its transparent practices, and a credit-based pricing system that allows users to pay for the specific data they need.
