### `examples` no Pydantic e no FastAPI { #pydantic-and-fastapi-examples }

Quando você adiciona `examples` dentro de um modelo Pydantic, usando `schema_extra` ou `Field(examples=["something"])`, esse exemplo é adicionado ao **JSON Schema** para esse modelo Pydantic.

E esse **JSON Schema** do modelo Pydantic é incluído no **OpenAPI** da sua API e, então, é usado na UI da documentação.
