EPC label, EPBD MEPS compliance, and stranding-risk screening across 8 EU markets — primary energy, solar obligation, renovation cost, and cap-rate discount modelling for lenders and asset managers.
Each endpoint returns specific data related to building energy compliance, including EPC labels, MEPS compliance status, energy use intensity (EUI), renovation costs, and risk assessments. For example, the POST Quick EPC Estimate returns estimated EPC labels based on monthly energy costs.
Key fields vary by endpoint but generally include status indicators, input parameters (like country and building type), calculated metrics (such as EUI and EPC labels), and compliance summaries. For instance, the POST Full EPBD Compliance Model includes fields for annual energy consumption and compliance deadlines.
Response data is structured in JSON format, typically containing a status field, input parameters, and a data section with calculated results. For example, the POST Portfolio Screening response includes a summary of total floor area and compliance risk for each asset analyzed.
Parameters vary by endpoint but often include country, building type, floor area, and energy consumption metrics. For example, the POST Renovation Sandbox allows users to specify retrofit measures to evaluate their impact on EPC labels and compliance status.
Data sources include national regulations, energy benchmarks, and research studies, such as Eurostat and JRC TABULA. Each endpoint's methodology is documented to ensure transparency and reliability, as seen in the GET Engineering And Regulatory Methodology Disclosure.
Typical use cases include assessing compliance risks for real estate investments, estimating renovation costs, and generating EPC labels for buildings. For instance, lenders can use the POST Stranding Risk Clock to evaluate the risk of non-compliance before loan maturity.
Users can leverage the returned data to inform decision-making regarding energy efficiency investments, compliance strategies, and risk assessments. For example, the POST Brown Discount Calculator helps determine adjusted bid prices based on compliance liabilities.
Data accuracy is maintained through regular updates, validation against national benchmarks, and adherence to established methodologies. Each endpoint's data is cross-referenced with authoritative sources to ensure reliability, as highlighted in the GET Country Regulatory Reference.
To obtain your API key, first sign in to your account and navigate to the API you want to use. From the API's Pricing section, choose a plan and complete the subscription process.

You can monitor your API usage through the response headers included with every request:
x-zyla-api-calls-monthly-used: Shows the total number of API requests you have used during the current billing period.
x-zyla-api-calls-monthly-remaining: Shows the number of API requests you have remaining for the current billing period.
Yes, you can cancel your subscription at any time. Simply go to the Pricing section of the API you're subscribed to and click the "Unsubscribe" button.
Please note that upgrades, downgrades, and cancellations take effect immediately. Once your subscription is canceled, access to the service will end immediately, regardless of any remaining API calls in your quota.
