Building a Multi-Asset Dashboard: Crypto, Forex & Stocks in One API

The Fragmentation Problem

Most developers use 3+ APIs for financial data: CoinGecko for crypto, Alpha Vantage for forex, Yahoo Finance for stocks. Three rate limits, three billing accounts, three SDKs.

One API, All Assets

The ChainSight API unifies crypto, forex, stocks, and commodities:

curl "https://chainsight-api.onrender.com/v1/forex/overview"

{
  "forex": [
    {"symbol": "EUR/USD", "rate": 1.1435, "change_pct": 0.12},
    {"symbol": "GBP/USD", "rate": 1.3251, "change_pct": -0.08},
    {"symbol": "USD/JPY", "rate": 148.92, "change_pct": 0.31}
  ],
  "stocks": [
    {"symbol": "SPY", "price": 589.73, "change_pct": 0.45},
    {"symbol": "AAPL", "price": 214.29, "change_pct": 1.23},
    {"symbol": "NVDA", "price": 135.40, "change_pct": -0.67}
  ],
  "commodities": [
    {"symbol": "Gold", "price": 3341.60, "change_pct": 0.31},
    {"symbol": "Oil", "price": 80.75, "change_pct": -0.22}
