This paper develops a real-variable and dyadic framework for hypersingular operators, particularly in regimes where strong-type estimates fail. It introduces a hypersingular sparse domination principle combined with Bourgain's interpolation method to establish critical-line and endpoint estimates. The work addresses a question raised by previous researchers and provides a new approach to analyzing related operators.
