CoinAPI Data Parser & API

CoinAPI is an institutional-grade cryptocurrency market-data aggregator that normalizes real-time and historical data from 350+ exchanges, and StockAPIS extracts its feeds — trades, quotes, OHLCV candles, order books and exchange metadata across 35,000+ assets — through a single unified REST API. CoinAPI offers a full official REST and WebSocket API, and StockAPIS normalizes it to the same schema you use for every other crypto-data source, so you query CoinAPI, Kaiko and on-exchange feeds the same way without maintaining separate integrations.

Platform Overview

Market Position

• A leading institutional crypto data aggregator unifying 350+ exchanges into one consistent schema
• 35,000+ assets spanning spot, derivatives, indices and reference data
• Single normalized symbol_id format (e.g. BINANCE_SPOT_BTC_USDT) across every venue
• Official REST, WebSocket and FIX APIs, complemented by StockAPIS’s unified normalization

Data Coverage

StockAPIS exposes the full CoinAPI market surface:

• Trades — tick-level executed trades with exchange and CoinAPI timestamps, size and taker side
• Quotes — best bid/ask and full L2/L3 order-book depth across venues
• OHLCV / candles — historical and real-time candlesticks from 1-second to monthly periods
• Exchange metadata — exchange lists, symbol mappings and instrument reference data
• Indices — CoinAPI reference rates and aggregated cross-exchange pricing
• Market data — 24h volume, latest price and cross-exchange aggregation per asset

Quick Start

import stockapis
 
client = stockapis.Client(api_key="your-api-key")
 
# Latest trade for a CoinAPI normalized symbol
btc = client.coinapi.get_ticker(symbol="BTC/USD")
print(f"Bitcoin: ${btc['price']}  ·  24h vol {btc['volume_24h']:,.0f} USD")

const { StockAPIS } = require("stockapis");
const client = new StockAPIS({ apiKey: "your-api-key" });
 
// OHLCV candles from CoinAPI's aggregated feed
const ohlcv = await client.coinapi.getOHLCV({
  symbol: "BTC/USD",
  period: "1DAY",
  limit: 100,
});
console.log(ohlcv[0]);
