CoinMarketCap Data Parser & API

CoinMarketCap is the world’s most-referenced cryptocurrency data aggregator, and StockAPIS extracts its market data — live prices, market cap, 24h volume, circulating and total supply, CMC rankings and global dominance metrics across 25,000+ coins — through a single REST API. CoinMarketCap offers an official Pro API, and StockAPIS normalizes it to the same schema you use for every other source, so you query CoinMarketCap, CoinGecko and on-chain feeds the same way without maintaining separate integrations.

Platform Overview

Market Position

• The #1 crypto data aggregator by traffic and brand recognition, owned by Binance
• Tracks 25,000+ cryptocurrencies across 700+ exchanges and 90,000+ market pairs

• Official Pro API (REST) with multiple tiers, complemented by StockAPIS’s unified normalization

Data Coverage

StockAPIS exposes the full CoinMarketCap data surface:

• Market quotes — real-time price, 24h volume, market cap and percent changes (1h/24h/7d/30d)
• Listings & rankings — CMC rank, market-cap-sorted coin lists with filters
• Supply data — circulating, total and max supply, plus fully-diluted valuation
• Token metadata — name, symbol, slug, contract address, tags, launch date
• Global metrics — total market cap, BTC/ETH dominance, active coins and exchanges
• Exchange data — exchange listings, reported volume and market pairs
• Historical OHLCV — daily and intraday history for backtesting and analytics

Quick Start

import stockapis
 
client = stockapis.Client(api_key="your-api-key")
 
# Latest market quote for a coin
btc = client.coinmarketcap.get_market_data(symbol="BTC", convert="USD")
print(f"Bitcoin: ${btc['quote']['USD']['price']:,.2f}  ·  rank #{btc['cmc_rank']}")

const { StockAPIS } = require("stockapis");
const client = new StockAPIS({ apiKey: "your-api-key" });
 
// Market-cap-ranked listings (top 10)
const listings = await client.coinmarketcap.getListings({ limit: 10, convert: "USD" });
console.log(listings.map((c) => `${c.cmc_rank}. ${c.symbol}`));
