Protocols HTTP/REST
All SDKs (Rust, TypeScript, Go, Python) and curl alike send queries as JSON to POST /v1/query on the default port 6969.

Queries are authored with the Rust, TypeScript, Go, or Python DSL and sent straight to a running instance as dynamic requests against `POST /v1/query` — no build or deploy step.
