Coinbase，相信大家都不陌生，世界顶级数字货币交易所。Coinbase 有非常完备的 API 服务，包括允许开发人员使用 OAuth2 协议允许 Coinbase 用户授予第三方应用程序对其帐户的完全或部分访问权限，而无需共享帐户的 API 密钥或登录凭据。
Coinbase, which I believe everyone knows, is the world's top digital currency exchange. Coinbase's API services are very comprehensive, it allows developers to use the OAuth2 protocol to allow a Coinbase user to grant a 3rd party application full or partial access to his/her account, without sharing the account’s API key or login credentials.
本篇文章，我们展示如何利用 Coinbase 的 Market Data API 获取交易对交易记录。
In this article, we show how to use Coinbase's Market Data API to list the latest trades for a product.
Market Data API 是 Coinbase Pro API 中不需要身份验证的公共信息端口，用于检索市场数据。它提供市场数据的快照。
The Market Data API is an unauthenticated set of endpoints for retrieving market data. These endpoints provide snapshots of market data.

获取交易对交易记录：
List the latest trades for a product:
https://api-public.sandbox.pro.coinbase.com/products/<product-id>/trades
比如查询 ETH-BTC 交易对：
For example, query ETH-BTC:
https://api-public.sandbox.pro.coinbase.com/products/ETH-BTC/trades
Node.js 代码示例：
Code example (Node.js):
const fetch = require('node-fetch');
fetch('https://api-public.sandbox.pro.coinbase.com/products/<product-id>/trades', {
method: 'get',
}).then(response => response.json()
.then(data => console.log(data)));
返回的 JSON 示例：
Return JSON example:
