A special endpoint e.g. /about or /license that lists the terms of the AGPL and a link to the source code would suffice. That's not difficult or unreasonable at all.

Where do you add that to redis, which does not have a HTTP server, and what makes this endpoint "prominent"?

>(if your version supports such interaction)

Put it on your website if redis does not support HTTP. The license clearly covers this.
