Loop through reference cursor insert into API and catch exceptions - plsql

Question

I am not sure why I am encountering an exception error. I am still learning PL/SQL. I am trying to put some data into a cursor from a table. Then loop through the cursor and insert the data into an API and catch the records that are rejected by the API's. Can I do one loop for multiple API's? Is there something else that I am missing?
