Upgrading our OTT Roku platform -- developer question

Question 

We currently have a live feed streaming on ROKU playing our content.    It works fine but want to upgrade to make it more competitive with similar apps. 

We week to combine MUVI with STRIMM so our platform will have more of a TUBI or FREEVEE feel.   Does anyone know if it is possible to embed these platforms on our WORDPRESS site and export the JSON to ROKU?   Or does anyone have a more practical solution?
