The platform covers nearly one million instruments across multiple asset classes, including stocks, forex, cryptocurrencies, ETFs, indices, and commodities[1][9]. Their data is available in both real-time and historical formats, with intraday intervals ranging from 1 minute to 8 hours and daily intervals from 1 day to 1 month[1].
The platform offers exceptional technical performance with 99.95% SLA uptime and ultra-low latency averaging ~170 milliseconds for real-time data streaming[8][11]. Twelve Data provides access to all major U.S. stock exchanges, over 90 international exchanges, and more than 180 cryptocurrency exchanges[4]. The service includes comprehensive fundamental data with global coverage from developed to emerging markets, featuring historical data dating back to the 1980s-90s sourced from income statements, balance sheets, and cash flow statements[2].
Technical analysis capabilities are robust, offering over 100 technical indicators including moving averages, RSI, MACD, and Bollinger Bands[4][10]. The platform supports multiple integration methods including REST APIs, WebSocket streaming, and SDKs for popular programming languages like Python and JavaScript[7][9].

How They Help Customers Trade More Effectively
Twelve Data enhances trading effectiveness through several critical capabilities that address the real-time demands of modern trading. The platform’s institutional-grade data quality ensures traders make decisions based on accurate, reliable information trusted by the largest financial firms[4]. The ultra-low latency of ~170 milliseconds provides a competitive advantage crucial for day trading and high-frequency strategies where milliseconds can determine profitability[8][11].
For cryptocurrency traders, the platform aggregates data from over 180 exchanges through a unified API, eliminating the complexity of connecting to multiple data sources[4]. The comprehensive coverage allows traders to monitor diverse portfolios across stocks, forex, and crypto markets from a single platform, streamlining their workflow and reducing integration costs[9].
The extensive historical data spanning over 30 years for daily intervals and multiple years for intraday data enables thorough backtesting of trading strategies[10]. This historical depth is essential for validating strategy performance across different market conditions. The platform’s technical indicators eliminate the need for manual calculations, allowing traders to focus on strategy development rather than data processing[9]. Real-time streaming capabilities through WebSocket APIs ensure traders receive immediate market updates, critical for executing time-sensitive trades[7].

A notable example includes an automated AI system that achieved 90%+ accuracy in gold market predictions using Twelve Data’s API combined with technical analysis and news sentiment evaluation[6].
The platform’s API structure is designed for seamless integration with popular AI and machine learning frameworks. The standardized JSON format and comprehensive SDK support facilitate easy data ingestion for Python-based ML libraries like scikit-learn and pandas[7]. The platform’s integration capabilities extend to workflow automation tools like Pipedream, enabling the creation of sophisticated automated trading systems that can execute market trend analysis, sentiment analysis alerts, and automated trading signals[7].
For AI model training, Twelve Data provides the extensive historical datasets necessary for developing robust predictive models. The granular intraday data from 1-minute intervals upward allows for detailed feature engineering and time-series analysis crucial for machine learning applications[1]. The platform’s real-time streaming capability through WebSocket APIs enables live AI model deployment, allowing algorithms to process market data and execute trades in real-time[7].
The technical infrastructure supports high-frequency data requests necessary for AI applications, with rate limits designed to accommodate both research and production environments[7]. The combination of fundamental data, technical indicators, and real-time market data provides rich feature sets that enhance AI model performance. Integration examples demonstrate practical implementations including automated trading signal generation, market sentiment analysis, and custom dashboard creation for AI-driven trading strategies[7][12].
