# Todo
* Add HTTP header authentication for endpoints that modify an owner's data.
* Add DELETE endpoints for existing resources.
* Add endpoints for the other models.
* Add caching. Not sure how to do this exactly. Could use Redis, Varnish, Nginx,
or a lib resident in the rust web server process. I'll probably need to do
invalidations as transactions are made, or interiors are updated.
* Make self-contained docker container that can run the app without any setup.
* Add rate-limiting per IP address. The `tower` crate has a service that might
be useful for this.
