Get the €STR as JSON-API

We build a simple API to get the current and historical €STR rates as JSON.

What is the €STR?

The €STR (Euro Short-Term Rate) stands as a crucial interest rate in Europe, delivered by the European Central Bank (ECB). It symbolizes the expense of acquiring funds for ultra-brief periods, often overnight. The €STR carries significant importance, functioning as a yardstick for loan interest rates, shaping the accessibility of funds for banks and businesses. The Euro Short-Term Rate has been assigned the international securities identification number (ISIN) EU000A2X2A25. Its variations influence economic judgments and policies in the Eurozone, where reduced €STR rates point to more economical borrowing, and elevated rates indicate heightened borrowing expenditures.

It's important to note that while we make every effort to ensure accuracy, we cannot guarantee the correctness of the received data.
