Call API every second

I want to call external api from backend side and want to update data in database.
How can I achieve this? Cron Job scheduler doesn’t support less than 1 hour interval.
Please help me.

Assume you’ve done this, calling Wix Data updates EVERY SECOND may takes things crash. You should call the API and display in front-end when user visit the site. Instead of pre-add items into Wix.

I want to sell product at live price along with I want to keep history of product price…If I will take control of price at user side for history management then it will be mismatch data from different data from different user at backend side
