Lerian SPB asks the STR for it with STR0001 at 04:00 Brasília on each weekday and applies on top every GEN0021 ("GEN avisa alteração de horários") announced for that day. Per grade code, a GEN0021 window wins, else the STR's eventual grade, else its standard grade placed on dtRef. An empty list means Lerian SPB holds no grade for the day: the STR has not answered, or no one asked for that day. ## OpenAPI ````yaml /pt/openapi/v3-current/spb.yaml get /v1/str/schedule openapi: 3.1.0 info: contact: email: contact@lerian.studio name: Lerian Studio url: https://lerian.studio description: >- OpenAPI 3.1 surface for Lerian SPB, the direct integration between the institution and the Brazilian Payment System (SPB) over the National Financial System Network (RSFN).
