The answer (STR0014R1, carrying the opening/closing balances and up to 200 settled entries) arrives asynchronously and is read via GET /v1/str/reserve-statement-queries/{id}. If BACEN routes the statement to a file (TamArq/IdentdArq) or the window exceeds the 200-entry message-mode ceiling, the read endpoint returns an explicit error — file retrieval (TpRet=P/X) is out of scope. Lerian SPB projects the statement BACEN sends; it never computes a position. ## OpenAPI ````yaml en/openapi/v3-current/spb.yaml post /v1/str/reserve-statement-queries 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).
