Rates

curve_history

One of B3’s FIXED vertices of a reference curve through time, oldest session first (b3_reference_rate, from 2008-01-02): a constant tenor exactly as B3 publishes it, never an interpolation. p_curve is PRE, DOC or DPL (see api.curve for what each is and its rate_basis, which rides on every row); p_tenor_days is the vertex’s NOMINAL tenor in calendar days (B3’s vertex_code: 1, 30, 60, 90 … 360 … 720 … 1800 … 10800), and calendar_days is its actual length that session, a day or two longer when the nominal date is not a business day. A tenor that is not one of B3’s fixed vertices raises 22023 listing the fixed tenors of the newest session; any other tenor is analysis — read api.curve and interpolate in the notebook. Long tenors sit in B3’s EXTRAPOLATED tail (past the last anchoring contract; B3 Manual de Curvas v21), which moves as contracts list and expire, so a long vertex can be extrapolation on one date and anchored on another. Default window the 12 months before p_to or today. More than 1000 rows RAISES 22023 (never trimmed): narrow p_from/p_to.

Row cap. A window producing more than 1000 rows raises SQLSTATE 22023 naming this function. Nothing is trimmed to fit — PostgREST would silently cut the response at 1000 and a cut-short series is indistinguishable from one that simply ends. This function does not page — narrow the window instead.

apikey

string

header

required

The publishable key (sb_publishable_…), on every request. It is NOT a JWT — sending it as Authorization: Bearer is rejected as an invalid JWT. It identifies the project, not you, and maps to the Postgres anon role.

p_from

Defaults to NULL::date.

Defaults to NULL::date.

The result set, oldest first. An unknown id is an empty array, not a 404 and never a guessed value.
