Request Rate Limit

The Upbit Open API service limits the number of requests per second to ensure a stable user experience. You can check the remaining number of requests via the "Remaining-Req" response header when calling the Open API.

Remaining-Req: group=default; min=1800; sec=29

For example, if you receive a response header like above, it means that within the "default" group, 29 requests are allowed for the current second.

🚧

If you exceed the rate limit, an HTTP 429 Too Many Requests error may occur. Continued violations can trigger temporary IP bans (HTTP 418). The block duration increases with repeated offenses.
Please retry after the time indicated in the error message.

The number of requests per second can be adjusted as needed to ensure stable service.
