Everything you need to know about the tounify API and our energy data.
tounify is a unified REST API that provides developers with direct access to comprehensive European electricity and grid tariffs. Instead of scraping dozens of provider websites or interpreting complex regulatory documents, you get clean, standardised JSON data for static, dynamic, and synthetic pricing models.
Yes, absolutely. We deliver exchange-linked dynamic tariffs, including day-ahead electricity prices based on the EPEX and North Pool spot markets. This is the exact data required to build intelligent Home Energy Management Systems (HEMS) or smart EV charging algorithms.
Dynamic tariffs (like exchange-linked prices) are synced daily as soon as the new spot market prices are published. Static and synthetic tariffs are continuously monitored by our automated crawlers and AI systems, ensuring you always operate on verified, up-to-date data.
tounify currently provides energy tariff data for 19+ European countries, including major markets like Germany, France, Italy, and Spain. We are constantly expanding our coverage. You can view the full list and live stats on our interactive coverage map.
Yes, that is one of our main use cases. By feeding our high-resolution tariff data into your algorithms, your applications can automatically schedule energy-intensive tasks (like charging an electric vehicle or running heat pumps) during the cheapest hours of the day.
No. You can request a test token completely free of charge and without a credit card. It gives you instant access to our API sandbox so your development team can evaluate the JSON endpoints and start building immediately.
