Use the RentRent API to return the rentals listed on Craigslist. You can search for rooms, apartments, or houses, and you can provide a parameter so that you only return rooms, versus apartments and houses. Also, you can provide parameters for min and max latitude and longitude, number of bedrooms, and number of bathrooms. You might integrate the data with Google Maps, Yahoo Maps, or Virtual Earth. Rentrent is not associated with Craiglist.org.
The following is a list of how-to and tutorial content that matched your search term. ProgrammableWeb's how-to content comes from two sources; full-blown tutorials that we publish ourselves and other highly relevant tutorials that we find elsewhere on the Web. This list represents on combination of both tutorial types and if you go to ProgrammableWeb's API University, you'll not only be able to find more, they are organized based on your role (API providers or developers who consumes APIs). If you know of a tutorial that would be of interest to the ProgrammableWeb community, we'd like to know about it. Be sure to check our guidelines for making contributions to ProgrammableWeb.
