Overview
MarketAux delivers real-time financial news with sentiment analysis, ticker tagging, and market statistics in a clean JSON format. It is designed for developers building stock market dashboards, trading tools, or finance apps. The free tier allows limited daily requests and is a great way to explore financial news data without upfront costs.
Beginner Tip
Filter by a specific stock ticker using the symbols parameter (e.g., symbols=AAPL) to get highly relevant financial news instead of broad market coverage. The sentiment field (positive, negative, neutral) is pre-calculated, saving you from building your own text analysis.
