This plugin adds a form to a website that fetches and displays official energy labels for buildings by querying a public data API. It is designed for real estate agents, property managers, and sustainability-focused websites that need to show energy efficiency information. Site visitors can enter a property's address details to see its certified energy performance rating.

• API Integration: Connects directly to the EP Online database to retrieve up-to-date, official energy label data using postcode, house number, and optional addition.
• Form Builder Compatibility: Includes a shortcode for use anywhere on the site and provides specific support for integration with the Elementor Pro page builder widget.
• Admin Configuration: Offers a dedicated settings page within the site's admin area to securely store and manage the required API access key.
• Frontend Presentation: Shows the retrieved label with a color-coded visual (from A+++ to G) and detailed supporting data like energy consumption, CO2 emissions, and property characteristics.
• Security and Validation: Implements nonce verification, input sanitization, and secure API request handling to protect the site and user data.
