* **Validate data**: coming from each request:
    * Generating **automatic errors** returned to the client when the data is invalid.
* **Document** the API using OpenAPI:
    * which is then used by the automatic interactive documentation user interfaces.

This might all sound abstract. Don't worry. You'll see all this in action in the [Tutorial - User Guide](tutorial/index.md).

Now you can go to [http://192.168.99.100/docs](http://192.168.99.100/docs) or [http://127.0.0.1/docs](http://127.0.0.1/docs) (or equivalent, using your Docker host).

You will see the automatic interactive API documentation (provided by [Swagger UI](https://github.com/swagger-api/swagger-ui)):
