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.

method: 'get',
}).then(response => response.json()
.then(data => console.log(data)));
返回的 JSON 示例：
Return JSON example:
