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

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

The actual callback is just an HTTP request.

When implementing the callback yourself, you could use something like <a href="https://www.python-httpx.org" class="external-link" target="_blank">HTTPX</a> or <a href="https://requests.readthedocs.io/" class="external-link" target="_blank">Requests</a>.

So, you can use `user_agent` as you normally would in Python code, instead of needing to capitalize the first letters as `User_Agent` or something similar.

If for some reason you need to disable automatic conversion of underscores to hyphens, set the parameter `convert_underscores` of `Header` to `False`:

  Just then she heard something splashing about in the pool a
little way off, and she swam nearer to make out what it was:  at
first she thought it must be a walrus or hippopotamus, but then
she remembered how small she was now, and she soon made out that

But at some point, there was no other option than creating something that provided all these features, taking the best ideas from previous tools, and combining them in the best way possible, using language features that weren't even available before (Python 3.6+ type hints).
