You'll want to look at the Corridor Search, which is part of the Search API Web Service. You have two options; you can either pass in the shapePoints that make up the route (corridor) that you want to search along, or you can use the Directions API to calculate a route and then use the sessionId from the Directions API response as input into the Search request.

Here's an example using the Directions API in conjunction with the Search API:

1. Use the Directions API to calculate a route between two points. In this example, I'm calculating a route between Denver, CO and Aurora, CO: http://www.mapquestapi.com/directions/v2/route?key=YOUR-APP-KEY-GOES-HERE&from=Denver,CO&to=Aurora,CO

2. Locate the sessionId parameter in the response.

3. Use the Search API to perform a corridor search on the uspostalcodes table. I'm also filtering the results from the table to include just the name of the postal code and none of the other info that is available in the table. http://www.mapquestapi.com/search/v2/corridor?key=YOUR-APP-KEY-GOES-HERE&sessionId=YOUR-SESSION-ID-GOES-HERE&width=1&buffer=0&hostedData=mqap.uspostalcodes|||POSTCODE

You can adjust the width/buffer options as well to refine your search. Hope this helps!
