But you still need to define what is the dependable, the callable that you pass as a parameter to `Depends()` or `Security()`.

There are multiple tools that you can use to create those dependables, and they get integrated into OpenAPI so they are shown in the automatic docs UI, they can be used by automatically generated clients and SDKs, etc.

You can import them from `fastapi.security`:

```python

    #  This property is valid only when isGenerateProcedureParameterBean is valid.
    #   e.g. list:{prefix:SP_}
    #  And you can specify procedures through DB link.
    #  This is treated as additional setting
    #  so it is independent from specifications for main schema.
    #   e.g. SP_FOO@NEXT_LINK (when DB link name is 'NEXT_LINK')  
    #

        }

        /**

         */
        public LsarClose(final rpc.policy_handle handle) {
            this.handle = handle;
        }

                String expectedNamespace,
                String expectedModelVersion,
                int expectedModifiedCount,
                String description) {

            String pomXml = PomBuilder.create()
                    .namespace(initialNamespace)
                    .modelVersion(initialModelVersion)
                    .groupId("test")
                    .artifactId("test")
                    .version("1.0.0")

Vamos ver como usar uma subclasse personalizada de `Request` para descomprimir requisições gzip.

E uma subclasse de `APIRoute` para usar essa classe de requisição personalizada.
