130 / 4500 is roughly 2.9% which seems reasonable - application fees are from the third party application ("platform") you use: https://stripe.com/docs/connect/direct-charges#collecting-fe...

Some on this forum may even say it's great that the APIs provided enable someone to build this additional payment app on top of Stripe that makes it easier for you to take payment in exchange for a 180 / 4500 = 4% cut. However maybe you should look into lower cost payment methods if possible.
