Integrating other authentication/authorization providers like Google, Facebook, X (Twitter), GitHub, etc. is also possible and relatively easy.

The most complex problem is building an authentication/authorization provider like those, but **FastAPI** gives you the tools to do it easily, while doing the heavy lifting for you.

    }

    @Test
    void testWithAnonymousCredentials() {
        CIFSContext wrappedContext = context.withAnonymousCredentials();

	defaultInterNodeJWTExpiry = 100 * 365 * 24 * time.Hour
)

var (
	errInvalidAccessKeyID = errors.New("The access key ID you provided does not exist in our records")
	errAccessKeyDisabled  = errors.New("The access key you provided is disabled")
	errAuthentication     = errors.New("Authentication failed, check your access credentials")
	errNoAuthToken        = errors.New("JWT token missing")

But at some point, there was no other option than creating something that provided all these features, taking the best ideas from previous tools, and combining them in the best way possible, using language features that weren't even available before (Python 3.6+ type hints).

Having `str | None` will allow your editor to give you better support and detect errors.

## Additional validation { #additional-validation }

We are going to enforce that even though `q` is optional, whenever it is provided, **its length doesn't exceed 50 characters**.

### Import `Query` and `Annotated` { #import-query-and-annotated }

To achieve that, first import:

* `Query` from `fastapi`
* `Annotated` from `typing`
