Each window carries the official grade code, opening/closing datetimes, schedule type and announcing provider, verbatim as announced. A re-announced grade for the same reference date overwrites the previous window. Optionally filter by reference date with dtRef. ## OpenAPI ````yaml en/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).
