Three Steps to Empower Your Application
From data integration to business impact
Connect
Receive your API token and integrate our REST API within minutes. Our documentation provides everything your developers need to start building on a solid data foundation.
Select
Filter by country, region, or provider. Your application gains instant access to thousands of verified static, dynamic, and synthetic electricity tariffs across Europe.
Empower
Deliver real-time price transparency to your users. Our high-resolution market data serves as the essential input for your consumption optimization and price forecasting models.
Market Models, One Interface
We normalize complex energy market structures into a clean, actionable data format.
Static Tariffs
Standardized energy pricing models, including time-of-use (TOU) rates like day/night or peak/off-peak variations.
Dynamic Tariffs
Real-time, exchange-linked pricing. Access day-ahead electricity prices and EPEX Spot market data streams required for smart charging.
Synthetic Tariffs
Complex models calculated based on supplier rules or regulatory authorities - fully decoded and normalized for your API.
Tariff data, no customer data
Feed-in & Grid Tariffs
Feed-in and grid tariffs alongside consumption rates, market by market. Essential for solar, battery storage, and prosumer applications.
Postal Code to Grid Operator
Resolve a postal code to its local distribution operator and bidding zone. Filter available DSOs for a postal code, no lookup tables to maintain.
National & Local Fees
In covered markets, electricity taxes, renewable levies and system charges are already inside the price we return. Some apply nationwide, others only in a single grid area or postal code - we resolve the most specific rule that applies, so you never assemble a levy table yourself.
Invoice-Based Gap Filling
Missing a tariff? Upload any electricity bill - we extract the rates and add them to the database. Coverage grows with every submission.
Anonymous by Design
We answer from tariff IDs alone. We never ask for - and never receive - your customers' names, accounts, meter readings or utility portal logins. The most we ever see is a postal code, and only when you choose to send one. There is no end-customer personal data in our systems to secure, and nothing for your privacy review to unpick.
Pan-European Energy Coverage
From the Nordics to the Mediterranean — 28 European nations, covering over 526.9 million inhabitants.

Active Markets
Every market we hold tariff data for. Depth varies by market — each card shows its tariff count, and the API's coverage endpoint reports the same figures live.
Missing your market?
Coverage expands regularly. If your target market isn't listed, reach out - we prioritize based on demand.
Request market coverageWhere do we get the data from?
To provide the most accurate energy API in Europe, tounify aggregates electricity data from a broad mix of independent channels - official market feeds, national regulators, grid operators, and live supplier data - all cross-checked against each other for accuracy.
Automated Web Crawler
Our specially developed crawler which regularly searches the trained websites of energy suppliers for price changes and tariff updates.
Live Market Feeds
Direct connections to European power exchanges and market operators deliver day-ahead spot prices daily, keeping dynamic and exchange-linked tariffs continuously up to date.
Synthetic Tariff Replication
Programmatic replication of synthetic tariffs based on published energy formulas and supplier rules.
Regulatory Documents
Extraction of tariff information from regulatory public documents and official government sources.
Open Data
Integration of numerous European open-data platforms - national energy agencies, grid operators and address registries - to enrich and continuously verify our electricity prices, and to map postal codes down to the distribution grid operator that actually serves them.
Manual Updates
Manual verification using our specially developed tool for complex or hard-to-automate market cases.
One API, many sources. We continuously combine more than ten official market and regulatory data feeds spanning over a dozen European markets, alongside hundreds of energy-supplier websites monitored automatically - so no single source can distort a price.
Simple, Scalable Pricing
Pay only for what you use. All plans include full API access and European coverage.

Buy a dataset outright
Some teams need the data once, not as a live feed. We deliver parts of our database as a one-off purchase - CSV or JSON, in the same normalised schema the API returns, net of VAT, in major currency, per kWh. The sets below are examples rather than a catalogue; each one reaches further than the few entries we can show here. Priced on request.
European Grid Tariff Sets
Grid fees per distribution operator, each market kept in its own national structure rather than flattened into a lowest common denominator. Every row is linked to the document it was read from.
Examples
- German Netzentgelte with the §14a EnWG Modul 2 and Modul 3 variants for the grid operators we cover, plus heat pump, e-mobility and storage heating tariffs
- Danish hourly time-of-use network tariffs, Dutch netbeheerkosten per connection size
- Austrian NE7, French TURPE
Regulatory Fee & Levy Register
In every market where we cover regulatory fees: the statutory charges between the wholesale price and the bill, each with its scope and validity dates, so past billing periods stay reproducible.
Examples
- National levies such as Stromsteuer, KWKG, Elafgift, Energiebelasting and accise
- Charges scoped to a single grid area, such as the Austrian Gebrauchsabgabe
- Charges scoped to a postal code, such as the Norwegian elavgift relief in the tiltakssone
Retail Tariff Snapshots & History
Point-in-time or historical extracts of the tariffs we track, versioned by the date each price took effect, so you can replay any past period.
Examples
- Consumption tariffs across the markets we cover
- Feed-in tariffs where suppliers publish them
- Static, dynamic and synthetic pricing models in one schema
Frequently Asked Questions
Everything you need to know about the tounify API and our electricity prices.
tounify is a unified REST API that provides developers with direct access to 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. Regulated components — network tariffs, levies and taxes — are refreshed from the regulator or grid operator on each publication cycle, many of them daily. Supplier tariffs are monitored for change and re-checked on a prioritised cycle, so the tariffs most customers depend on are revisited most often. Every tariff is versioned by the date its price took effect: the versions endpoint lists those dates, and you can ask for a price as of any one of them. A price response names the tariff, not the version it applied, so an integration that has to prove which prices it used records the date it asked for and reads the version list beside it.
tounify currently provides tariff data for 28 European countries, including major markets like Germany, France, Italy, and Spain. Depth varies by market — see the tariff count per country on our interactive coverage map. We are constantly expanding our coverage.
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. Creating an account issues a testing token straight away — free of charge, no credit card, and no waiting on a sales reply. Your development team can evaluate the JSON endpoints and start building immediately. A testing token is meant for evaluation rather than production: it expires, and the number of different companies and tariffs it may ever query is capped and does not reset, so explore deliberately. The API reference states the current allowances, and we raise them on request.
