Quarterly Period Import

Hello, quarterly imports do not seem to be working when changing period to quarterly. I have tried q, quart, quarter, quarterly, qtr. Nothing seems to be working. Here is an example.

=(IMPORTDATA("https://api.roic.ai/v2/fundamental/income-statement/TMUS?period=qtr&limit=10&format=excel&apikey=APIHERE","\t")) where qtr can be replaced with all the above but none seem to work.
