## What it is
A Go middleware library by Auth0 that validates JSON Web Tokens (JWTs) on incoming HTTP requests, with a framework-agnostic core validator. Version 3 adds gRPC interceptors, functional-options configuration, and JWKS support via lestrrat-go/jwx.

## Use cases
- protect Go HTTP API endpoints with JWT authentication
- validate bearer tokens in Go web requests
- add JWT auth middleware to net/http or gin apps
- verify JWTs from Auth0 in a Go backend
- authenticate gRPC services with JWT interceptors
- validate tokens against a JWKS endpoint in Go

## When to choose
- you need JWT validation middleware for Go HTTP services
- you use Auth0 or another OIDC issuer and need token verification
- you want gRPC and HTTP JWT auth from one library

## When to avoid
- you need to issue or sign JWTs rather than validate them
- you need full OAuth2/OIDC flows, not just token checking
- your stack is not Go
