## Install custom exception handlers { #install-custom-exception-handlers }

You can add custom exception handlers with <a href="https://www.starlette.dev/exceptions/" class="external-link" target="_blank">the same exception utilities from Starlette</a>.

Let's say you have a custom exception `UnicornException` that you (or a library you use) might `raise`.

        The WWW-Authenticate header is not standardized for API Key authentication but
        the HTTP specification requires that an error of 401 "Unauthorized" must
        include a WWW-Authenticate header.

        Ref: https://datatracker.ietf.org/doc/html/rfc9110#name-401-unauthorized

        For this, this method sends a custom challenge `APIKey`.
