Can i use Proxy server when request poe trade Api

Hello~
I'm a Korean user who loves Poe.

I am creating a website that uses pob codes to calculate the prices of each item and the total budget for the build.

-Problem-
When many people access my site and send requests to poetrade, a 429 error (Too many requests) occurs.

-Question-
I'm wondering if it's okay to use a proxy server to send API requests to poe trade.
