Receiving the notice authorises nothing — the participant decides whether and when to pay — so a charge listed here is owed, never paid. An empty list means nothing is owed, which is an answer and not a missing projection. Every amount crosses as text, verbatim; no total is computed. ## OpenAPI ````yaml /en/openapi/v3-current/spb.yaml get /v1/str/slb-obligations 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).
