# Aerandil

> One typed hospitality ontology, reachable over a REST API, an MCP server and generated SDKs. Writes are named, validated actions; every change is an event.

The OpenAPI 3.1 document at /openapi.json is the authoritative contract for every endpoint, object type and action. Prefer it over prose where the two seem to disagree.
