hey is there a way to verify if an HTTP request is sent from a frame? like an access token

use case: I'd like to authenticate requests server side for permissioned endpoints

maybe not 100% assurance, but if you only generate auth token in frame when sdk.isLoaded and use that auth token in the request, you can be pretty confident

not sure if answering your question exactly

you can! if i understand correctly

take signature sdk.signIn in frame from custody address and use custody address to verify fid via neynar

thanks! Ideally I could pull the fc account info from that auth token, or a signature client side then verify it on backend

this has me thinking, appreciate this MJC!
