A key BACEN DICT does not hold answers 404 with code SPI-1015; any other BACEN DICT refusal answers 422 with code SPI-1011. ## OpenAPI ````yaml /pt/openapi/v3-current/spi-dict.yaml get /api/v1/dict/entries/{key}/statistics 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).
