## Introduction

The **Subsidies API** is a powerful tool designed to help users navigate sustainability funding opportunities across the Netherlands. It aggregates information from **national**, **provincial**, and **municipal** programs, providing a unified platform for discovering subsidies and loans that support eco-friendly home improvements and energy transition projects.

Beyond discovering available programs, the API offers advanced **loan calculation capabilities**. It allows users to estimate **interest rates**, **total amounts**, and **monthly payments** based on parameters such as loan duration, income, and repayment period.

The main objectives of the Subsidies API are to:

* **Retrieve** real-time subsidy and loan data from official government sources.
* **Evaluate eligibility** based on key input parameters (e.g., income, home ownership status, and desired loan period).
* **Recommend optimal loan options**, including detailed calculations of **total interest**, **overall cost**, and **estimated monthly installments**.

By consolidating complex financial data into a single, easy-to-use service, the Subsidies API empowers individuals and organizations to make informed decisions about sustainable investments.
