SBS Transit is blocking local app developers from grabbing information about bus arrival times from the SBS Transit website thus crippling popular local apps.
These include apps such as tranSGuide and Gothere.sg. Among the apps that are still work are the newer versions of SG NextBus, SG Buses V3 and of course, SBS Transit Iris.
SBS Transit is blocking developers by requiring all queries sent via the web interface to pass a Captcha challenge-response test. The test requires that the person key in the validation number presented on the page. Humans using the service can easily pass the test and get the necessary data. However, automated scripts will have difficulty passing this test and will thus be denied access.
This roadblock also affects Android and Windows Phone 7 apps that rely on SBS Transit's data.
We have contacted SBS Transit and will update this story if they respond.
