How it behaves

Spot yields across 11 maturities, from 3 months to 30 years, in two variants: AAA-rated issuers only, and all euro area government issuers.
The points come ordered by real maturity, not alphabetically. Sorting by text would give 10Y, 15Y, 1Y, 20Y, 2Y… — a curve drawn that way looks like noise. luni is the maturity in months, used for ordering and useful for interpolation.
Of the 1,083 series in the dataflow we take only these two representations: the rest are the same quantity expressed differently — Svensson parameters, instantaneous forwards, par yields — that is, millions of rows with no new information. The maturities are configurable, so the set can be extended without code.

What it is for

Drawing the yield curve.
Discounting a cash flow at market yields.

Error codes

Code	Slug	When it occurs
401	neautentificat	Missing or invalid token.
403	feature_indisponibil	`financiar.bce` is not in the current plan.
429	cota_depasita	The plan's rate limit or quota has been exceeded.

All errors share the same shape. eroare.cod is stable and is the value you should branch on in code — not the text in mesaj, which may change.
