CoinCap 是查询超过1,000种加密货币实时定价和市场活动的有用工具。通过收集来自数千个市场的交换数据，能够提供有关资产价格和可用性透明而准确的数据。本文整理 CoinCap API 查询主流交易所交易基本数据的基础操作和介绍。
CoinCap 对于所有端口，默认情况下，单个页面提供100个响应，并且在请求时每页最多支持2,000个响应。
CoinCap API 服务包括 RESTful API 和 WebSocket API 两种。通过 CoinCap API 查询数据不需要申请密钥。
基础查询语句：
api.coincap.io/v2/exchanges
Node.js 代码示例：
const fetch = require('node-fetch');
fetch('https://api.coincap.io/v2/exchanges', {
method: 'get',
}).then(response => response.json()
.then(data => console.log(data.data)));
返回的JSON示例：
