It covers settlement-operation intake and lifecycle, clearing positions, the participant and arrangement registry, generated reports, embedded XSD schema introspection, transmission recovery and connectivity to Núclea, BYOK Model-A signing-key import, and tenant-scoped webhooks. title: Lerian SLC API version: 1.0.0 servers: - url: https://slc.sandbox.lerian.net security: - BearerAuth: [] tags: - description: >- Settlement operation lifecycle — create, list, query, and control the NUliquid-tracked card operations (NUliquid = the 21-position id Núclea assigns each accepted operation) through the state machine. name: Operations - description: >- Participant catalog — the acquirers, sub-acquirers, IF Domicílio (bank where the merchant receives its sales), and settlement FIs (financial institutions) that take part in card settlement. name: Participants - description: >- Card arrangements (bandeira/scheme configurations, e.g. Visa/Master/Elo) attached to a participant. name: Arrangements - description: >- Regulated transport orchestration to Núclea/SILOC (the private card clearing house that operates the SILOC settlement system) — dispatch, recovery, retransmission, and connectivity testing over managed file-transfer, message-broker, and REST. name: Connectivity - description: >- Multilateral netting clearing positions — the net amount each participant settles per STR cycle (STR = Banco Central reserves-transfer system). name: Clearing - description: >- SaaS BYOK (Bring Your Own Key) signing-key provisioning — import parameters and register the client's ICP-Brasil A1 (Brazilian PKI server certificate, 1-year validity) certificate material used to sign ASLC files; the private key never leaves the client's HSM/KMS/Vault. name: SigningKey - description: >- ASLC file intake and status — passthrough submission and processing status of the official Núclea card-settlement XML files (ASLC = Arquivo do Sistema de Liquidação de Cartões). name: Files - description: >- Read-only introspection of the embedded Núclea ASLC/RSFN (National Financial System Network) XSD schemas used to validate outbound and inbound messages. name: XSD Schemas - description: Read-only regulatory, compliance, and operational settlement reports. name: Reports - description: >- Outbound business-event webhook subscriptions and delivery management for consumers (Midaz, client ledgers, Cabine — all optional). name: Webhooks - description: >- Administrative operations — hot-reloadable runtime configuration, dead-letter-queue inspection/replay, and outbox redispatch. name: Admin paths: /v1/operations: get: tags: - Operations summary: List settlement operations description: >- Lists settlement operations for the request tenant, filtered and paginated.
