Trying to achieve a login endpoint at a laravel installation by using tymon/jwt-auth (JWT). The login, logout, get userdata is working fine. I would like to have a endpoint for checking the Bearer Token. There is a short way to achieve this via:

```
Route::get('/valid', function () {
    return 1;
})->middleware('auth:api');

```

If the token is valid, the the HTTP return code == 200 but if not, a 401 code is returned. Since the endpoint is checking a token and not the authenticated communication, I would like to rather have a controller returning true/false regarding valid token with 200 - OK.

I had a look "under the hood" of the modules and that is how far I get (not working):

```
            $tokenKey = $request->bearerToken();
            $jws = \Namshi\JOSE\JWS::load($tokenKey);

            $jwsSimple = new SimpleJWS($jws->getHeader());
            $jwsSimple::load($tokenKey);
            $jwsSimple->setPayload($jws->getPayload());
            $jwsSimple->setEncodedSignature(explode('.', $tokenKey)[2]);

            $tmpVal = $jwsSimple->isValid($tokenKey);

```

Is there any better approach to achieve this? I assume that there should be a Service Provider for that but could not figure out how to implement this. Thank you in advance.
