Answer 1

There is a limit basically: 1,000 free requests per 24 hour period, calculated as the sum of client-side and server-side requests. If your app exceeds the initial limit, the app will start failing.

Quoting https://developers.google.com/webmaster-tools/search-console-api-original/v3/limits:

The Search Analytics resource enforces the following limits:

Per-site limit (calls querying the same site):

• 5 QPS
• 200 QPM

Per-user limit (calls made by the same user):

• 5 QPS
• 200 QPM

Per-project limit (calls made using the same Developer Console key):

• 100,000,000 QPD

Example

• User A can make up to 5 QPS combined to her 3 websites.

• Users A and B can make up to 5 QPS combined to their one website.

All other resources

Per-user limit (calls made by the same user):

• 20 QPS
• 200 QPM

Per-project limit (calls made using the same Developer Console key):

• 100,000,000 QPD

• QPS: Queries / second
• QPM: Queries / minute
• QPD: Queries / day
