O que o FastAPI realmente verifica, é se a dependência é algo chamável (função, classe, ou outra coisa) e os parâmetros que foram definidos.

Se você passar algo "chamável" como uma dependência do **FastAPI**, o framework irá analisar os parâmetros desse "chamável" e processá-los da mesma forma que os parâmetros de uma *função de operação de rota*. Incluindo as sub-dependências.
