Narrow with source to read one leg, or with referenceDate to read the hours that apply to one day. Projected verbatim (Catálogo de Serviços do SFN v5.13, Vol II): the câmara's own clock, its own 5-character grid code, and no canonical window resolved from either. ## OpenAPI ````yaml /en/openapi/v3-current/siloc.yaml get /api/v1/siloc/schedule/grids openapi: 3.1.0 info: description: >- OpenAPI 3.1 surface for Lerian SILOC, the participant-side rail connecting the institution to Núclea's SILOC deferred-net interbank settlement. title: Lerian SILOC API version: 1.0.0 servers: - url: https://siloc.sandbox.lerian.net security: [] paths: /api/v1/siloc/schedule/grids: get: tags: - Schedule summary: List the grades de horário the câmara published description: >- Every grade de horário this rail received from the SILOC câmara, newest reference date first — both the unsolicited change advice (LDL0024) and the answers to schedule queries this institution issued (LDL0023R1), with source saying which leg delivered each row.
