Stop Juggling Finance APIs — Get Stocks, Crypto & Funding Data From One Endpoint

#api #finance #javascript #webdev

Building a finance dashboard? You've probably hit the same wall I did — one API for stock quotes, another for crypto prices, yet another for startup funding rounds. Each has its own auth, rate limits, and response format. It's a mess.

The Multi-Source Finance Data Hub API solves this by aggregating data from Yahoo Finance, Crunchbase, and CoinGecko into a single, unified REST interface. One API key, one consistent response shape, all the financial data you need.

What You Get

  • Stock quotes — real-time price, volume, market cap, and daily change for any ticker
  • Crypto prices — current pricing, 24h trends, and market data for thousands of tokens
  • Startup funding — investment rounds, valuations, and investor details from Crunchbase

The main /quote endpoint accepts a symbol parameter and an optional type parameter (stock or crypto). That's it.

Quick Example

Here's how to fetch Apple's stock data with a single fetch() call:

const response = await fetch(
  'https://consol-finance-api-production.up.railway.app/api/quote?symbol=AAPL&type=stock'
);
const data = await response.json();

console.log(data.name);        // Apple Inc.
console.log(data.price);       // current price
console.log(data.marketCap);   // market capitalization
console.log(data.changePercent); // daily % change
Enter fullscreen mode Exit fullscreen mode

Swap type=stock for type=crypto and pass a crypto ID to get token data instead:

const crypto = await fetch(
  'https://consol-finance-api-production.up.railway.app/api/quote?symbol=bitcoin&type=crypto'
).then(res => res.json());

console.log(crypto.price);     // BTC price in USD
console.log(crypto.volume24h); // 24-hour trading volume
Enter fullscreen mode Exit fullscreen mode

Why This Beats Calling Each Source Directly

  1. One integration instead of three separate API setups
  2. Normalized responses — no more writing adapters for different data shapes
  3. Single rate limit to manage instead of juggling quotas across providers
  4. Less code — fewer dependencies, simpler error handling, faster shipping

Whether you're building a portfolio tracker, a fintech prototype, or a market research tool, having stocks, crypto, and funding data behind one endpoint cuts your integration time significantly.
