## Combine predefined responses and custom ones

## Automatic docs

The JSON Schemas of your models will be part of your OpenAPI generated schema, and will be shown in the interactive API docs:

And will also be used in the API docs inside each *path operation* that needs them:

All these dependencies, while declaring their requirements, also add parameters, validations, etc. to your *path operations*.
