Engineering guides and tutorials for financial data APIs

The RealMarketAPI blog publishes technical guides, integration walkthroughs, and platform announcements for developers working with real-time and historical financial market data. Articles cover the full stack — from authenticating with your API key and crafting your first REST request, through to running persistent WebSocket connections for sub-second OHLCV feeds, computing technical indicators server-side, and wiring the MCP server to Claude or GPT-4o for AI-driven market analysis.

Every post is written by the engineering team that builds and operates the platform. Code samples are runnable and tested against the live API — available in Python, JavaScript/TypeScript, and cURL. Where a guide covers a specific endpoint, it links directly to the interactive API Playground so you can execute requests immediately. Data examples use production symbols: XAUUSD (spot gold), BTCUSD, EURUSD, US500, USOIL, and other commonly traded instruments.

Recurring series include: WebSocket integration patterns for live charting and price alerting bots; technical indicator guides for RSI, MACD, Bollinger Bands, ATR, and Stochastic Oscillator; historical OHLC data use cases from backtesting to machine learning feature pipelines; and MCP server tutorials for building autonomous market-aware AI agents. Platform update posts cover new endpoint releases, symbol additions, latency improvements, and SDK updates.
