#### OpenAPI и JSON Schema { #openapi-and-json-schema }

OpenAPI определяет схему API для вашего API. И эта схема включает определения (или «схемы») данных, отправляемых и получаемых вашим API, с использованием стандарта **JSON Schema** для схем данных JSON.

#### Посмотрите `openapi.json` { #check-the-openapi-json }
