/// note | Nota

Algunos códigos de response (ver la siguiente sección) indican que el response no tiene un body.

FastAPI sabe esto, y producirá documentación OpenAPI que establece que no hay un response body.

## Acerca de los códigos de estado HTTP

/// note | Nota

Si ya sabes qué son los códigos de estado HTTP, salta a la siguiente sección.

* **`300 - 399`** are for "Redirection".  Responses with these status codes may or may not have a body, except for `304`, "Not Modified", which must not have one.
* **`400 - 499`** are for "Client error" responses. These are the second type you would probably use the most.
    * An example is `404`, for a "Not Found" response.

      This is a set of Artifact instances resolved from the set of dependencies for
      the current project.

      NOTE: This will likely contain much more than the direct dependencies of the
      current POM, since Maven uses transitive, or chained, dependency resolution.

When you use the `async` methods, **FastAPI** runs the file methods in a threadpool and awaits for them.
