A small self-hosted caching proxy. Point it at an origin, it keeps a copy on local disk and serves it back. This is the admin API.
All calls use a bearer token from your config file. There is one token per install.
curl -H "Authorization: Bearer $TOKEN" http://127.0.0.1:8080/v1/status
The API listens on loopback by default. Put it behind your own TLS if you expose it.
