How this service works
Euro area AAA government bond yield curve (zero-coupon, 3 months to 30 years) estimated by the ECB, with change in basis points versus N days ago and the 10y-2y slope.
Output
Returns a JSON object with the curve date, an array of maturity buckets (e.g. 3M, 6M, 1Y … 30Y) each containing the zero-coupon rate in percent and the change in basis points versus the comparison date, the comparison date itself, the source attribution (ECB), and the 10y-2y slope in basis points.
Example use cases

Endpoint
POSThttps://api.vextorium.com/v1/euro-yield-curve?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need the official ECB zero-coupon euro area AAA government bond yield curve with multi-maturity coverage (3M to 30Y), basis-point change comparisons, and the 10y-2y slope in a single call. Prefer it over generic bond data sources when ECB methodology and AAA-only filtering are required, or when you need the slope metric precomputed.
Side effects
- ECB data not yet published for the current day — response may return the most recent available date
- compare_days out of range (must be 1–365) — may return a validation error
- Upstream ECB data source temporarily unavailable — service may return an error or stale data
- Invalid body type supplied — request rejected
