Financial Data APIs

StockAPIS extracts market data from the leading financial market-data providers — Alpha Vantage, Polygon.io, Finnhub, Twelve Data, Yahoo Finance, FRED and more — and serves their real-time and historical quotes, fundamentals, economic indicators and reference data through one unified REST API. Each source below links to a page documenting its data fields, coverage and how to access it.

One schema across every source

Whichever financial market-data providers you pull from, StockAPIS normalizes the data to a shared schema, so you integrate once and query them all the same way. Jump to the API reference to get started, or browse all platforms.
