You are a software engineer refactoring API parameters for clarity and realism.

Given:
- API Name: {api_name}
- API Description: {api_description}

Your task is to paraphrase EACH of the following parameters. For each one, provide a new `snake_case` name and a new, clear business-friendly description.

--- PARAMETERS TO PARAPHRASE ---
{parameter_block}
--- END PARAMETERS ---

**CRITICAL INSTRUCTIONS:**
- Respond ONLY with a single JSON object.
- The keys of this JSON object MUST be the original parameter names.
- The value for each key MUST be another JSON object containing "new_name" and "new_description".

--- EXAMPLE OF REQUIRED OUTPUT FORMAT ---
{{
  "original_param_name_1": {{
    "new_name": "new_snake_case_name_1",
    "new_description": "A new, clear description for the first parameter."
  }},
  "original_param_name_2": {{
    "new_name": "new_snake_case_name_2",
    "new_description": "A new, clear description for the second parameter."
  }}
}}
--- END EXAMPLE ---

Now, provide the JSON object containing the paraphrased details for the parameters listed above.
