  title: Twelve Data REST Core Data Technical Indicators API
  description: 'REST API for Twelve Data financial market data covering stocks, forex, cryptocurrencies, ETFs, indices, commodities, and funds. Provides historical and real-time time series (OHLCV), quotes and prices, 100+ technical indicators, reference / catalog data, and company fundamentals. All requests are authenticated with an apikey supplied either as a query parameter (?apikey=) or via the `Authorization: apikey <KEY>` header.
