does the xbee pro xsc s3b support api mode

The docs for xbee pro xsc s3b doesn’t list the AP command for switching into API mode. Whenever I try to use it in XCTU, I get an error. So does this model of radio support API mode?

No, the XSC code does not support API mode. It is designed to communicate with the old XStream product which did not have an API interface.
