Arbitrum Mainnet 403 client error when calling contract

Questions

Hello,

I am currently trying to do some contract calls on Arbitrum Mainnet but I get thrown the following exception:
“requests.exceptions.HTTPError: 403 Client Error: Forbidden for url: https://arbitrum-mainnet.infura.io/v3/XXXXXXXXX”

I am a free tier user and wanted to know whether its because of that status or something else.
The functions i am calling are:
“balanceOf”
“stakingToken”
“earned”

Would be cool to receive some some help…thanks

Best,

Hey, @friedefuerst! Welcome to the community! You need to add the new Arbitrum Network Add-on to your account if you haven’t done that part yet. Can you confirm?
Plus, can you provide the snippet of the code?
