What does an inverted yield curve mean?

An inverted yield curve means short-term bonds yield more than long-term bonds. It often precedes recessions as markets expect central banks to cut rates. An inverted curve has preceded every US recession since 1970.

Does the server require an API key?

No, the ECB's public API endpoints do not require any form of authentication or API tokens to fetch statistical data.

What maturities are included in the yield curve?

The government bond yield curve data covers maturities ranging from 3 months all the way up to 30 years, giving a complete perspective on borrowing costs.
