Rates

future_curve

Every outright DI1 futures contract on one B3 session (B3 Price Report BVBG.086.01, b3_futures_settlement), nearest maturity first, as published: settlement_rate (% a.a., 252 business days) and settlement_price (the PU, R$; 100,000 at maturity), the previous settlement rate, open_interest, contracts traded, trades, notional_brl and the session’s open/low/high/avg/close — which for DI1 are RATES, because B3 quotes DI1 in rate (the low rate is the high price). contract_month is the one derived column: the first day of the month the ticker names, read with B3’s month letters (F = January … Z = December); the contract matures on that month’s first business day. p_root is DI1 (the only root held); p_trade_date NULL = the newest session held, and a date with no session (a holiday, or before 2018-01-02, when B3’s Price Report history starts) returns no rows. More than 1000 rows RAISES 22023 (never trimmed); one session holds about 50.

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.

Body

p_root

string | null

default:DI1

Defaults to 'DI1'::text.

p_trade_date

string<date> | null

Defaults to NULL::date.

Response

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