SSE é comumente usado para streaming de chat de IA, notificações em tempo real, logs e observabilidade, e outros casos em que o servidor envia atualizações para o cliente.

/// tip | Dica

Essa parte é bastante normal, a maior parte do código provavelmente já é familiar para você:

{* ../../docs_src/openapi_callbacks/tutorial001_py310.py hl[7:11,34:51] *}

/// tip | Dica

O parâmetro de consulta `callback_url` usa um tipo Pydantic [Url](https://docs.pydantic.dev/latest/api/networks/).

///

Você pode definir `"json_schema_extra"` com um `dict` contendo quaisquer dados adicionais que você queira que apareçam no JSON Schema gerado, incluindo `examples`.

/// tip | Dica

Você poderia usar a mesma técnica para estender o JSON Schema e adicionar suas próprias informações extras personalizadas.
