To manage the cost of using Google APIs, you can set everyday quota limits to any billable API on all requests. Most APIs have default limits, but that can be adjusted up to a maximum limit as specified by Google.
Here are a few steps you must follow to change or view daily quota limits for your API:
Step 1: Go to the Google Maps Platform Quotas page in the Cloud Console.
Step 3: You can now scroll down to the Map loads option to view the quota limits. You will see a list of different quota names and limits.
Step 4: In the next step, you can change the quota limit by clicking on the Edit icon. Enter your preferred billable quota limit (for instance, you can set the 'Maps loads per day' to 400) and click Save.
Note: Only billable APIs allow you to set daily quota limits. If your project does not use any billable APIs, then you won’t be allowed to set any daily quota limits.
On any given day, if your API usage reaches or exceeds your billable quota limit, your application will be unable to use the API for the rest of the day.
