About Data Captain
Data Captain is a US ETF data platform for developers, analysts, and fintech builders. One API key unlocks market data, backtests, and portfolio tools — so you ship products instead of stitching together vendor spreadsheets.
What we build
Our REST API and official SDKs (npm datacaptain, PyPI datacaptain) cover the ETF universe, batch prices, screeners, heatmaps, rankings, historical OHLCV, strategy backtests, and portfolio rebalance helpers. Free tier for exploration; paid plans when you need history and higher limits.
Who it is for
- Developers embedding ETF data in apps and dashboards
- Quants and researchers running reproducible backtests
- Analysts comparing funds and screening the ETF universe
- Fintech teams that want predictable JSON and clear rate limits
