If you need to, you can do some caching into your own database, that could help instead of accessing the foursquare API each time you need information. Depending on how you DB/application is structured, this is particularly useful if you need to run jobs or need to access the foursquare data in a static way. If you're using a NoSQL database, I encourage you to dump the full venue information in your stored document. If you're using SQL based, store it as a Blob and reference to venue_id.

Does it help?
