Qrlew Server API
Qrlew is Sarus's open-source (Apache 2.0) SQL manipulation and differential-privacy engine, written in Rust and published under github.com/Qrlew. The Qrlew server wraps it in a small RESTful API — POST /dot, /rewrite_as_privacy_unit_preserving, /rewrite_with_differential_privacy, /verify and GET /public_key — distributed as the container image ghcr.io/qrlew/server:main and run by the operator. The demo host the README names (qrlew.sarus.app) no longer resolves to a live service, so this is a self-hosted surface only.
