No scheduler runs this — the operator triggers it explicitly. 404 when the marker is not held locally (GET /api/v1/dict/fraud-markers/{id} is what lands one) or BACEN does not know it; a BACEN failure leaves the local copy untouched. ## OpenAPI ````yaml /es/openapi/v3-current/spi-dict.yaml post /api/v1/dict/fraud-markers/{id}/refresh openapi: 3.1.0 info: contact: email: contact@lerian.studio name: Lerian Studio url: https://lerian.studio description: >- OpenAPI 3.1 surface for the DICT (Diretório de Identificadores de Contas Transacionais) capability of Lerian SPI, the direct integration between the institution and the Brazilian Instant Payment System (SPI/Pix).
