**FastAPI** está todo basado en Pydantic.

Vas a ver mucho más de esto en práctica en el [Tutorial - User Guide](tutorial/index.md){.internal-link target=_blank}.

## Type hints en **FastAPI**

**FastAPI** aprovecha estos type hints para hacer varias cosas.

Con **FastAPI** declaras los parámetros con type hints y obtienes:

    TF_EXCLUSIVE_LOCKS_REQUIRED(fn_body->mu) {
  input_tensors->reserve(ninputs);
  for (int i = 0; i < ninputs; ++i) {
    Node* node = inputs[i].oper ? &inputs[i].oper->node : nullptr;
    int idx = inputs[i].index;

    TF_RETURN_WITH_CONTEXT_IF_ERROR(
        fn_body->graph.IsValidOutputTensor(node, idx),
        "Encountered while processing input ", i, " into function '", fn_name,
        "'");

/// info

In this example we use invented custom headers `X-Key` and `X-Token`.

But in real cases, when implementing security, you would get more benefits from using the integrated [Security utilities (the next chapter)](../security/index.md){.internal-link target=_blank}.

## Dependencies errors and return values

You can use the same dependency *functions* you use normally.
