The Geocoding API offers a number of ways to geocode data. For example, you can perform searches by entering an address, or by specifying a location and then using a different method for finding information about that location. The Geocoding API is recommended for queries involving address-specific information, such as street addresses. It is not recommended for queries with ambiguous addresses, or for queries with non-address information.
The geocoder returns results in JSON format, so you can use it with any application. It also tries to use the user’s native language. This means that it will attempt to return a readable street address in the preferred language. It also transliterates the results to a user-friendly script when necessary.
Geocoding APIs are available from different companies. For example, Google provides a free version and a paid one. If you want to use Google’s geocoding API, you can request a free trial and test it out to see how it works. If you’re not satisfied with the free version, you can pay for a paid version and get unlimited geocoding.
The geocoding API should have the ability to check the address against an authoritative database. This process is called address validation, and it is the first step to world-class geocoding. If an address is invalid, the service should return a status code indicating that it is invalid. This allows the user to fix the request if necessary.
