Korea Investment & Securities Launches "Open API Activation Campaign"... Expands API Call Limit Up to 5 Times

Korea Investment & Securities announced on August 31 that it is launching the “Open API Activation Campaign” to improve the digital investment environment for individual investors and enable them to implement their own investment ideas into actual systems.

This campaign is designed to provide a stable and efficient environment for customers who actively trade using the Open API.

If a customer meets the average daily trading value criteria for the most recent five trading days, the API call limit will be expanded to up to 100 TPS (requests per second) until December 31. The basic call limit currently offered is 20 TPS. The campaign will run until October 30.

An additional event will be held for new and dormant customers to expand the user base for the Open API service. The eligible participants are new customers or those who have not engaged in domestic stock or domestic derivatives trading through Open API from June 1 to August 27. If they execute trades of at least 100 million won in domestic stocks or at least 500 million won in domestic derivatives through the Open API, they will receive a mobile gift voucher worth 10,000 won.

A representative from Korea Investment & Securities stated, “The Open API is more than just an order channel—it is a digital investment platform that helps investors combine their ideas and data to build their own investment systems. As advancements in AI technology lower the barriers for individual investors to utilize APIs, we will continue to strengthen a differentiated digital investment environment where customers can experience the full process, from learning and practical application to strategy enhancement.”
