Using google maps without API Keys?

Question

I am developing a CMS that will use more than one domain and I have to use only one google map script in my page.

Is there a way to use google maps without API key?

Otherwise, it's not working?

Answer 1

The Google Maps API V3 does not require a key.

Like V2, however, you can only use it for applications which are free and publicly accessible. If it's for a commercial product, you'll need the Google Maps API Premier
