このスキーマ定義はAPIパス、受け取り可能なパラメータなどが含まれます。

#### データ「スキーマ」

「スキーマ」という用語は、JSONコンテンツなどの一部のデータの形状を指す場合もあります。

そのような場合、スキーマはJSON属性とそれらが持つデータ型などを意味します。

#### OpenAPIおよびJSONスキーマ

OpenAPIはAPIのためのAPIスキーマを定義します。そして、そのスキーマは**JSONデータスキーマ**の標準規格に準拠したJSONスキーマを利用するAPIによって送受されるデータの定義（または「スキーマ」）を含んでいます。

#### `openapi.json`を確認

素のOpenAPIスキーマがどのようなものか興味がある場合、FastAPIはすべてのAPIの説明を含むJSON（スキーマ）を自動的に生成します。

// would wait before working on next object.

In that case, it would mean the JSON attributes, and data types they have, etc.

#### OpenAPI and JSON Schema

OpenAPI defines an API schema for your API. And that schema includes definitions (or "schemas") of the data sent and received by your API using **JSON Schema**, the standard for JSON data schemas.

#### Check the `openapi.json`
