The API functions are powered by Geocaching Live
API query dialog
Through the API you can make a direct query on the Geocaching.com database. You may query by centerpoint with a distance and refine your query on several properties of caches. You may also query on GC Codes.
You can query lite descriptions, without Logs, Additional Waypoints and offline descriptions to speed up the download. When you download the full description you get these properties and also the amount of Favoritepoints (not available in pocketqueries).
(Full descriptions only for Premium members)
Getting found caches
When you click the option in the account preferencepane, iCaching will check for your found caches since the last time you checked. This way your database will keep in sync with your geocaching history.
You can go further back in history by downloading more found caches by rightclicking the ‘My Found caches’ in the Library.
Add and remove Favoritepoints
Check geocache availability
From the cache list you can update geocache availability by rightclick on a selection, or by clicking the ‘refresh’ button in the lower left corner. iCaching will check the available status through the API. This prevents you from seeking archived caches in the field.
