Aurastream

One endpoint. 10+ data sources. Zero infrastructure.

Aurastream is a unified financial data API. Instead of integrating with each exchange and data provider individually, make a single POST request to Aurastream and get OHLCV bars, trades, quotes, funding rates, economic indicators, and more.
