### Documentar no OpenAPI e sobrescrever `Response` { #document-in-openapi-and-override-response }

#### 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 }

#### OpenAPI et JSON Schema

**OpenAPI** définit un schéma d'API pour votre API. Il inclut des définitions (ou "schémas") de la donnée envoyée et reçue par votre API en utilisant **JSON Schema**, le standard des schémas de données JSON.

#### Allez voir `openapi.json`

### Generate a TypeScript Client with the Preprocessed OpenAPI { #generate-a-typescript-client-with-the-preprocessed-openapi }

Since the end result is now in an `openapi.json` file, you need to update your input location:

```sh
npx @hey-api/openapi-ts -i ./openapi.json -o src/client
```

### OpenAPI { #openapi }

O **FastAPI** gera um "*schema*" com toda a sua API usando o padrão **OpenAPI** para definir APIs.

#### "*Schema*" { #schema }

Um "*schema*" é uma definição ou descrição de algo. Não o código que o implementa, mas apenas uma descrição abstrata.

#### API "*schema*" { #api-schema }

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

OpenAPI define un esquema de API para tu API. Y ese esquema incluye definiciones (o "esquemas") de los datos enviados y recibidos por tu API utilizando **JSON Schema**, el estándar para esquemas de datos JSON.

#### Revisa el `openapi.json` { #check-the-openapi-json }
