The Problem with Financial Data

Building anything stock-related means stitching together data from Yahoo Finance, SEC filings, social platforms, and analyst sites. Each source has its own format, rate limits, and quirks. You end up spending more time wrangling data than building features.

The Stock Market Intelligence Platform API consolidates 10+ financial data sources into one clean REST interface. Real-time quotes, fundamental analysis, insider trading activity, analyst ratings, earnings transcripts, and social sentiment — all from a single API key.

What You Get

The core /api/stock-quote endpoint returns comprehensive data for any ticker symbol. Pass include_extended=true to pull pre-market and after-hours pricing as well.

Here's a working example that fetches a quote for Apple:

const response = await fetch(
  'https://stock-market-intel-api-production.up.railway.app/api/stock-quote?symbol=AAPL&include_extended=true',
  {
    method: 'GET',
    headers: {
      'X-RapidAPI-Key': 'YOUR_RAPIDAPI_KEY',
      'X-RapidAPI-Host': 'stock-market-intelligence.p.rapidapi.com'
    }
  }
);

const data = await response.json();

console.log(`${data.symbol}: $${data.price}`);
console.log(`Change: ${data.changePercent}%`);
console.log(`Volume: ${data.volume.toLocaleString()}`);

The response includes current price, volume, day range, 52-week range, market cap, and extended hours data when requested.

Use Cases

Portfolio trackers — fetch live quotes for a watchlist and display P&L
Trading bots — combine price data with sentiment scores for signal generation
Research dashboards — surface insider buying patterns alongside analyst consensus
Discord/Slack bots — let users type $TSLA and get an instant snapshot

Why This Over Scraping

Scraping financial sites breaks constantly and violates most ToS. This API normalizes data from multiple sources, handles upstream changes, and returns consistent JSON every time. You get reliability without maintenance overhead.
