The service provides capabilities to upload one-way messaging from remote locations to a feed accessible by others. It transfers message data via satellites of the global positioning system (GPS) to allow hikers and others in remote terrain to report progress and emergency situations to those monitoring the service from distant locations. Messages post to an established feed for access in varying amounts and timeframes suited to specific monitoring needs.
API methods support retrieval of the latest message in a specified feed or all messages uploaded over a specified date range. For more comprehensive access, the API gives access to the most recent 50 messages or the entire feed in pages of 50 messages.

For example, the Ruby SDK for consuming the Twitter Ads API.
