As @iaincollins said, I want to use Cloudflare workers to read and validate a JWT. Currently, I used Cloudflare Workers for 2 APIs in my websites.

This may be saved for users 200-400ms if their location is too far deployed server.

I checked this problem was implemented on auth0: https://github.com/auth0/nextjs-auth0/blob/c485044/src/frontend/use-user.tsx#L136
