In this case, this `__call__` is what **FastAPI** will use to check for additional parameters and sub-dependencies, and this is what will be called to pass a value to the parameter in your *path operation function* later.

## Parameterize the instance { #parameterize-the-instance }

And now, we can use `__init__` to declare the parameters of the instance that we can use to "parameterize" the dependency:

import com.github.ajalt.clikt.parameters.arguments.help
import com.github.ajalt.clikt.parameters.options.default

import com.github.ajalt.clikt.parameters.options.help
import com.github.ajalt.clikt.parameters.options.multiple
import com.github.ajalt.clikt.parameters.options.option

    }

    /**
     * Builds parameter maps for search initialization, creating both query strings
     * and form inputs for the given parameters.
     *
     * @param paramMap the parameter map to process
     * @param queryKey the key for storing query string parameters
     * @param formKey the key for storing form input parameters
     */

# Path Operation Configuration { #path-operation-configuration }

There are several parameters that you can pass to your *path operation decorator* to configure it.

/// warning

Notice that these parameters are passed directly to the *path operation decorator*, not to your *path operation function*.

///

## Response Status Code { #response-status-code }

You can define the (HTTP) `status_code` to be used in the response of your *path operation*.

        default:
            return "Unknown error: 0x" + Integer.toHexString(returnCode);
        }
    }

    /**
