# IEX Cloud

> IEX Cloud was a cloud-based financial data platform from IEX Group offering market data, fundamentals, news, options, and reference APIs. The service was SUNSET on August 31, 2024: all API endpoints (cloud.iexapis.com, api.iex.cloud) are unreachable, and the iexcloud.io domain has since lapsed to a third-party domain-parking page. This profile is preserved as historical reference for migration patterns. Commonly cited successor providers: Polygon.io, Tiingo, Alpha Vantage, Finnhub.

Important: do not call these APIs — they no longer exist. Credentials (publishable/secret tokens) are invalid.
