Travis CI Insights does not work to me

Travis CI - Test and Deploy with Confidence looks amazing to me but, it does not look like working.

https://api.travis-ci.com/insights/metrics?subject=builds&interval=1day&func=sum&name=count_started&owner_type=User&owner_id=1226114&end_time=2022-07-02+01%3A50%3A08+UTC&start_time=2022-06-26+00%3A00%3A00+UTC&private=true return 401 error.
