Free geocoding service with non-restrictive license

I am looking for a geocoding service where I can make a request with an address or intersection, not necessarily separated into separate fields (street, city, state, etc.) and get the latitude and longitude, along with suggestions and corrections for misspelled or ambiguous queries.

I really like the Google Geocoding API, but the terms of use say that I am not allowed to store the responses or use the service for any purpose other than showing the result on one of their maps. I am planning to use it for a lightweight, mobile-friendly website that may have the option of displaying results with text only, so this would not work, assuming I am interpreting their terms correctly.

The Yahoo PlaceFinder API looks nice but it comes with similar restrictions.

I am trying to decide what would be a good choice. The Bing API looks good. I don't see any sort of restriction in their terms but am I missing something?

Does anyone know what would be a good choice? I have very limited funding, so I would prefer something that is free or cheap, at least for the 开发者_如何学Pythonnear future.

You could try Nominatim, it's a tool to search OpenStreetMap data by name and address.

MapQuest provide a free API as long as you give the appropriate credit

I'm not sure how well it handles misspellings or ambiguous queries though!
