Can I (and how to) use styled google maps without API

Question

I am theme developer. For my template I have plugin where user can set options for google map and of course generate this on template page. But not everyone have google maps API key. I don't wanna demand from user his api key. I have also seen template written by someone else and no one wanted from user his api key. So what should I do now with this?

Another question is what javascript code should I use to generate map? In my form I have following fields:

Map Height (px): (int)

Google Map Address 1: (eg. Wiejska 8 Warsaw)

Google Map Address 2: (optional)

Google Map Address 3: (optional)

Google Map Address 4: (optional)

Google Map Address 5: (optional)

Zoom Level: (int)

Zoom Map on Mouse Wheel: (YES/NO)

Custom Map Style: (YES/NO)

Color Overlay: (eg #FFF)

Saturation: (int)

Lightness: (int)

Yes, at least for now you can use Google maps without an API key. See Using google maps without API Keys? for a discussion on the subject.

As for what your code should look at, take a look at Google's examples . Play around with them, and if you run into issues feel free to ask more specific questions.

Happy coding!
