A Google Geocoding API is a great way to quickly create interactive maps. You can use the service for unlimited lookups, but beware of overage fees. In the past, you were limited to 50 requests per second, or one per second per application. Overage fees can lead to errors, watermarks, and even block your access to the API. To avoid paying excessive fees, you should sign up for a billing account with Google. You will then be able to pay a low, flat fee of around $200 a month.
A Google Maps API key is a personal code provided by Google that grants access to Google Maps on this site. Each Google user gets a 200-credit-per-month quota, and after that, they will be automatically billed based on usage. You can get a Google Maps API key in a few minutes. To use this service, you must have a billing account.
Developers can access the Maps Platform for free by using a valid API key and a billing account on Google Cloud Platform. However, the $200 credit will only allow developers to access static maps, and not the Routes and Places products. This is a serious limitation, especially for small businesses and those with a small user base. In addition to this, a developer must have a Google Cloud Platform account.
