Also the output of the bx tools are not (easily) parseble usually.

So it would be a great help, if these tools would provide option to

a) suppress such output like " 64.00 KiB / 13.00 MiB    0.48% 3.11 MiB/s 00m04s"

b) provide alternative output formats like json, so the responses like "Session: 91234567-8901-2345-6789-901234567890 is created" could be easily parsed
