You can get a quota of 100,000 requests per day if you confirm your identity:
Users who verified their identity using the API console allowed 100,000 requests in 24 hours. Credit card required. to verify by enabling billing in the console. We ask you for a credit card to verify your identity. Your map will not be used by Places APIs.
You will find this information and much more if you go to the Google APIs Console, select "Services" and click on the "Pricing" link in the "Location addresses" line.
100,000 requests per day are many and should be sufficient if your application is not extremely popular. And I donβt think that creating multiple users to create multiple API keys will be possible without violating Googleβs terms and conditions.
