A new module for CityGrid (Citysearch) APIs

I've just completed a working version of a module that fetches information from Citysearch. It utilizes the APIs recently made available to the public, proxied by the Mashery. I do have some issues with the APIs but for the most part it is functioning as I expected. This is my first module offering to the general drupal community. I have now installed the module on my production site, with the nolog toggle on. The module creates a block that contains a form for inputting selection criteria. The first Search API returns either a list of locations or a list of events as a json object (using curl). The object includes links for the Profile API, which returns information specific to a business. This object in turn contains links for the Reviews API. Display of these objects is controlled by jQuery Ajax calls that in turn hide divs and display divs.

I would appreciate hearing any thoughts about this. I don't have a CVS account and I have not been officially part of any particular projects but I have been working with drupal since the release of version 6. This is my first relatively complex module and I would like to get feed back on not only the code itself but best practices issues as well.
