Google Books API的费率限制是多少？
我有兴趣进行大约12k的ISBN查询以找到书籍的类别。但是，我会收到HTTP错误429，并且在尝试整理它时，我找不到有关请求限制的任何信息（每秒，每分钟，每小时等）。
有人知道Google Books API的速率限制吗？
I'm interested in doing around 12K total ISBN queries to find books' categories. However, I get an HTTP error 429 and when trying to sort it out, I couldn't find any info on the limit of requests (per second, per minute, per hour, etc).
Does anyone know the rate limits for the Google Books API?

您可以在 Google Cloud Console
库 - ＆GT;搜索API - ＆GT;单击管理 - ＆GT; Quota Tab
默认值似乎是
有两种类型的配额。基于项目和基于用户的。
基于项目的配额涵盖了您的所有用户及其对您的项目本身的计数。
基于用户的配额将取决于使用您的系统的用户。它要求您根据请求发送Quotauser或Userip。这基本上是防洪。
You can see your current quota for any api you have enabled in your project on Google cloud console
Library -> search for the api -> click manage -> quota tab
Default seems to be
There are two types of quotas. Project based and user based.
The project based quota covers all your users and its counted against your project itself.
User based quotas will depend upon the user using your system. It would require that you send quotaUser or userIp with your request. This is basically flood protection.
