Using findAddressCandidates without hosting

Question

I have a program which requires the latitude and longitude of United States addresses. It is not hosted by ArcGIS, it is simply a program which runs on my local box and needs a few address coordinates. I am using the REST interface to findAddressCandidates, using curl to execute the URL and retrieve the data returned. As an example, I am using a URL similar to this:

http://tasks.arcgisonline.com/ArcGIS/rest/services/Locators/TA_Address_NA_10/GeocodeServer/findAddressCandidates?Address=380+New+York+Street&City=Redlands&State=CA&Zip=92373&f=json&pretty=true

I have been told that this URL will no longer be supported in 2014. The ArcGIS documentation still includes information on how to use the rest interface to findAddressCandidates. Will there be a new URL for this kind of query? Can geocoding with ESRI be done without hosting an app on ArcGIS? If so, how?

Correct, to store the data, you will need to have an online subscription.

In short, you will be sending in credentials/authentication along with the request.  This is what will allow for tracking/billing.

You don't have to host this application on ArcGIS.com. You can keeping running it from your local machine.

There is more information on authentication at https://developers.arcgis.com/en/authentication/.  It depends somewhat on your current workflow/technology.

Thanks for the reply.

I would like to store the results on my own local database. The business I work for is happy to pay ESRI's reasonable rates for geocoding. So, after I have an account setup, do I need to write an app similar to the one described previously, or is there a way to send credentials to the geocoding web service, or perhaps a third solution?

1. Can I use the World geocoding service without an online account? The link you posted gives me results, implying that it would not be required.

Yes, you can use it without an online account.

It's not required.
