This schema definition includes your API paths, the possible parameters they take, etc.

#### Data "schema"

The term "schema" might also refer to the shape of some data, like a JSON content.

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

#### OpenAPI and JSON Schema

    Although in FastAPI it's optional, and is used mainly to set headers, cookies, and alternative status codes.

### <a href="https://moltenframework.com/" class="external-link" target="_blank">Molten</a>

I discovered Molten in the first stages of building **FastAPI**. And it has quite similar ideas:

* Based on Python type hints.
* Validation and documentation from these types.
* Dependency Injection system.

    },
    "paths": {
        "/items/": {
            "get": {
                "responses": {
                    "200": {
                        "description": "Successful Response",
                        "content": {
                            "application/json": {



...
```

#### Для чего нужен OpenAPI

Схема OpenAPI является основой для обеих систем интерактивной документации.

```Python hl_lines="7"
{!../../../docs_src/query_params_str_validations/tutorial013.py!}
```

!!! note
    Dans ce cas-là, **FastAPI** ne vérifiera pas le contenu de la liste.

    Par exemple, `List[int]` vérifiera (et documentera) que la liste est bien entièrement composée d'entiers. Alors qu'un simple `list` ne ferait pas cette vérification.

    },
    "paths": {
        "/items/": {
            "get": {
                "responses": {
                    "200": {
                        "description": "Successful Response",
                        "content": {
                            "application/json": {



...
```

#### Wofür OpenAPI gedacht ist

    },
    "paths": {
        "/items/": {
            "get": {
                "responses": {
                    "200": {
                        "description": "Successful Response",
                        "content": {
                            "application/json": {



...
```

#### OpenAPIの目的

OpenAPIスキーマは、FastAPIに含まれている2つのインタラクティブなドキュメントシステムの動力源です。
