About

Twelve Data is a single API that covers more than a million instruments across stocks, currencies, crypto, ETFs, and commodities, plus built-in technical indicators. You can use it to build a multi-asset portfolio tracker, to fetch a stock's RSI or moving average without writing the math yourself, or to compare ETF prices side by side. The free plan runs on an API-credit system with a daily refill.
