Free multi-asset databank with file and API access
What it is
A hosted databank of market and economic series that you can browse, chart, and download as Parquet or CSV once a free key is issued. Coverage includes stock ticks and candles, US option prints with implied volatility and greeks, currencies, crypto, futures, ETFs, commodities, indices, government bond yields, and macro series, plus a REST API and a live WebSocket. Researchers and independent quants who want a broad free archive without running their own collectors are the audience. The free plan limits how many slices you may pull each hour and how many rows each slice may contain.
