Fastest way to check if a Roblox cookie is valid or invalid?

Hello there I had recently encountered a problem where I wasn’t able to check if a Roblox cookie is valid or invalid and I was suggested by a friend to use an API but the result isn’t satisfactory as it takes time.

I was wondering if there was anyway to check which wouldn’t involve any sort of API

If login fails then it is invalid, what are you trying to utilize this for, a bot or what?

I don’t really think you can check if a cookie is valid or invalid without using an API.

How would I know if the login failed, I’m trying to change the cookie not log into the account.

The best way would probably be sending a GET request to Roblox with appropriate .ROBLOSECURITY cookie.
Should get you those information.

That’s what I currently do but sending requests would be really slow for me.

Then there’s no different option. You cannot just validate a cookie without contacting Roblox api in any way. Even if cookie format is appropriate, tokens do expire.
