Api Fetch

Is it possible to do a research by job and city by adapting it to my site via a json data (like this short code:[wpjobportal_job]) and to list the last jobs published (like this short code:) ? Same question, to filter data (like this short code: [wpjobportal_job_search]) ?

Thank you for advance for your answer. Any help can be grateful for me in order to achieve my studies…

Block with my urlMySite/wp-json, no access to data in order to use this data…
