API rate limits define the number of requests that can be made to the
Google Compute Engine API. API rate limits
apply on a per-project basis. When you use
or the Google Cloud Platform Console, you are also making
requests to the API and these requests count towards your API rate limit, if
applicable. If you use service accounts to access the API, that will also count
towards your rate limit.
Currently, projects are limited to an API rate limit of 20 requests/second.
If you need a higher rate limit for API requests, you can request an increase via the Google Cloud Platform Console
