In this case, it will be mounted at the path `/subapi`:

{* ../../docs_src/sub_applications/tutorial001_py39.py hl[11, 19] *}

### Check the automatic API docs { #check-the-automatic-api-docs }

Now, run the `fastapi` command with your file:

<div class="termy">

```console
$ fastapi dev main.py

This could be useful if for example you live in a country that restricts some URLs.

### Disable the automatic docs { #disable-the-automatic-docs }

The first step is to disable the automatic docs, as by default, those use the default CDN.

To disable them, set their URLs to `None` when creating your `FastAPI` app:

				<artifactId>maven-javadoc-plugin</artifactId>
			</plugin>
			<plugin>
				<artifactId>maven-jar-plugin</artifactId>
				<configuration>
					<archive>
						<manifestEntries>
							<Automatic-Module-Name>org.codelibs.fess.crawler.lasta</Automatic-Module-Name>
						</manifestEntries>
					</archive>
				</configuration>
			</plugin>
			<plugin>
				<groupId>com.mycila</groupId>
				<artifactId>license-maven-plugin</artifactId>

Even if they are in different modules (Python files).

## Exclude from OpenAPI { #exclude-from-openapi }

To exclude a *path operation* from the generated OpenAPI schema (and thus, from the automatic documentation systems), use the parameter `include_in_schema` and set it to `False`:

{* ../../docs_src/path_operation_advanced_configuration/tutorial003_py39.py hl[6] *}

			</plugin>
			<plugin>
				<artifactId>maven-jar-plugin</artifactId>
				<configuration>
					<archive>
						<manifestEntries>
							<Automatic-Module-Name>org.codelibs.fess.crawler.opensearch</Automatic-Module-Name>
						</manifestEntries>
					</archive>
				</configuration>
			</plugin>
			<plugin>
				<groupId>com.mycila</groupId>
				<artifactId>license-maven-plugin</artifactId>

        "name": "The Foo live"
    }
}
```

Again, doing just that declaration, with **FastAPI** you get:

* Editor support (completion, etc.), even for nested models
* Data conversion
* Data validation
* Automatic documentation

## Special types and validation { #special-types-and-validation }

Apart from normal singular types like `str`, `int`, `float`, etc. you can use more complex singular types that inherit from `str`.

    /**
     * Number of days to keep search logs before purging.
     * Set to -1 to disable automatic purging of search logs.
     */
    @Min(-1)
    @Max(100000)
    @ValidateTypeFailure
    public Integer purgeSearchLogDay;

    /**
     * Number of days to keep job logs before purging.
     * Set to -1 to disable automatic purging of job logs.
     */
    @Min(-1)
    @Max(100000)
    @ValidateTypeFailure

Again, just with that same Python type declaration, **FastAPI** gives you automatic, interactive documentation (integrating Swagger UI).

Notice that the path parameter is declared to be an integer.
