Question

Is there a generic JavaScript or possibly Python/Django or other open source web service or API to look up a geolocation given a street address? http://www.braincastexception.com/wp7-web-services-first-part-geocodeservice/ does what I want, apparently in C#. Is the like available from JavaScript or open source projects that can be queried?

Check out Gisgraphy a free an open source geo service.

Everyone will tell you to use the Google Maps API but read the terms of use.

(g) No Use of Content without a Google Map. You must not use or
display the Content without a corresponding Google map, unless you are
explicitly permitted to do so in the Maps APIs Documentation, or
through written permission from Google. In any event, you must not use
or display the Content on or in conjunction with a non-Google map. For
example, you must not use geocodes obtained through the Service in
conjunction with a non-Google map. As another example, you must not
display Street View imagery alongside a non-Google map, but you may
display Street View imagery without a corresponding Google map because
the Maps APIs Documentation explicitly permits you to do so.

So with the Google API you must use a Google Map. So if you need a map you’re OK.
