Optional status/kind facets; cursor-paginated (the underlying table is actively mutated by the sweep, so an offset page could skip or repeat a row). Same sanitized per-item projection as GET /operations/{id}. ## OpenAPI ````yaml /en/openapi/v3-current/spi-dict.yaml get /api/v1/dict/operations 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). It covers the PIX key lifecycle, portability and ownership claims, the MED 2.0 dispute surface (infraction reports, refunds, fraud markers, and funds recoveries), antifraud statistics, synchronous DICT reports, and the internal operations that keep the key directory consistent. license: name: Lerian Studio General License title: Lerian SPI — DICT API version: 1.0.0 servers: - url: https://spi.sandbox.lerian.net security: [] tags: - description: 'PIX key lifecycle: register, list, search, lookup, delete, and statistics.' name: Keys - description: >- PIX key portability and ownership claims through their full lifecycle (initiate, confirm, reject, cancel, acknowledge, complete). name: Claims - description: 'DICT infraction reports: list and retrieve.' name: Infractions - description: 'DICT refund requests: create, list, and retrieve.' name: Refunds - description: 'PIX fraud markers: create, list, and statistics.' name: Fraud Markers - description: >- Durable MED operation-intent status: the operationId every create/lifecycle-transition backlog route returns or references on every outcome, queryable independently of the business resource. name: Operations - description: >- Synchronous reports over Lerian SPI's own DICT record: COUNT(*) summaries of keys (by type/status) and claims (by type/status + open-past-deadline).
