ptax_daily

BACEN’s PTAX buy and sell rate per business day and currency (bacen_ptax), BRL per ONE unit of the currency, as published. The same rows as api.ptax, for every currency at once, filtered with PostgREST syntax (?currency=eq.USD&date=gte.2026-01-01). Nothing is derived or filled. A GET returns at most 1000 rows, the OLDEST first: filter on currency and date and read Content-Range.

Paging. A GET view pages normally with limit/offset (and Range). Every response is cut at 1000 rows server-side regardless of tier; read Content-Range to detect it (0-999/* is a truncated page, and Prefer: count=exact turns the * into the total).
