Best Finance APIs for Developers

A finance API allows developers to retrieve stock prices, market indices, earnings data, company financials, and investment metrics programmatically. These APIs are the foundation of fintech apps, trading dashboards, and personal finance tools.

CodeHelper's curated finance API collection includes APIs covering equities, ETFs, options, company fundamentals, and macroeconomic indicators.

What to look for in a finance API

  • Data latency: Real-time trading apps require live data feeds, while portfolio trackers can often use 15-minute delayed data available on free tiers.
  • Historical depth: For backtesting investment strategies, APIs with 10+ years of daily OHLCV data are essential.
  • Fundamental data: P/E ratios, earnings, and balance sheets enable more sophisticated investment analysis applications.
