### Notes

- This endpoint returns the full prompt body content, unlike other endpoints that only return metadata
- The `promptVersionId` must be a UUID, not the 6-character prompt ID
- Template variables in the format `{{ hc:variableName:type }}` can be used for dynamic content
- Use the `/v1/prompt-2025/query/versions` endpoint to get the version UUID from a prompt ID
