Is there a list of Resource-based APIs and Client-based APIs

[pramodbiligiri]

In a documentation page regarding authentication (

https://cloud.google.com/docs/authentication/provide-credentials-adc#user-creds-client-based) it is mentioned that there are two kinds of Google Cloud APIs:
1. Resource-based APIs, which use the resources being accessed for billing and quota,
2. Client-based APIs, which use the account accessing the resources for billing and quota.

Which of these API types does the Cloud Pubsub API come under? Is there a list somewhere that categorizes all GCP APIs under one of these two?

I found two links that would probably help you.

The first one is All APIs and References, and the second one is Google APIs explorer.
