E o Swagger UI tem suportado esse campo `examples` particular há algum tempo. Então, você pode usá-lo para **mostrar** diferentes **exemplos na UI da documentação**.

O formato desse campo `examples` específico do OpenAPI é um `dict` com **vários exemplos** (em vez de uma `list`), cada um com informações extras que também serão adicionadas ao **OpenAPI**.

* Generate <a href="https://json-schema.org" class="external-link" target="_blank">JSON Schema</a> definitions for your model, you can also use them anywhere else you like if it makes sense for your project.
* Those schemas will be part of the generated OpenAPI schema, and used by the automatic documentation <abbr title="User Interfaces">UIs</abbr>.

 * amortized since some operations can trigger a hash table resize.

                those two instead of this one, as those allow returning `None` values
                when it makes sense.

Vamos a empezar desde donde lo dejamos en el capítulo anterior e incrementarlo.

## Acerca de JWT { #about-jwt }

JWT significa "JSON Web Tokens".

Es un estándar para codificar un objeto JSON en un string largo y denso sin espacios. Se ve así:
