调用api实现ChatGPT接口余额查询

在ChatGPT官网可以查询接口使用额度，但是官方并没有提供相应的API给开发者调用。我们可以通过破解的方式找到它的API。方法如下：

1. 使用Chrome浏览器打开https://platform.openai.com/account/usage

2. 打开开发者工具，然后刷新网页，如下就是要调用的API

3：具体的API说明：

https://api.openai.com/dashboard/billing/usage?end_date=2023-05-01&start_date=2023-04-01 其中Header中需要加入你自己的apiKey，使用crul如下：curl https://api.openai.com/dashboard/billing/usage?end_date=2023-05-01&start_date=2023-05-12 \ -H "Authorization: Bearer 你自己的APIKEY" \

说明一下请求参数：查询范围包含start_date这一天，不包含end_date这一天，前闭后开。

返回报文如下：

说明一下返回报文：cost字段对应的数值为美分，不是美元。
