Requests the deposit itself, for assets the câmara already accepted through LDL1002; each asset names the original Número Controle Requisição IF and Número Controle Aceite LDL (Vol II, Evento LDL1003 Descrição). RLDL0008: one custody transfer that produces several allocations repeats its Selic or CETIP operation number once per Entidade Responsável 2. The request is minted, built, signed, encrypted and durably recorded BEFORE anything reaches the queue, so this returns 202 with the control number the câmara will echo; the answer (LDL1003R1) arrives asynchronously and is read back with getLDL1003. Every amount and quantity is a decimal STRING carried to the wire exactly as written. A deployment with no send leg configured answers 503 with SILOC-0023; one whose dispatcher is not running answers 503 with SILOC-0024. ## OpenAPI ````yaml /es/openapi/v3-current/siloc.yaml post /api/v1/siloc/outbound/deposit-requests openapi: 3.1.0 info: description: >- OpenAPI 3.1 surface for Lerian SILOC, the participant-side rail connecting the institution to Núclea's SILOC deferred-net interbank settlement. title: Lerian SILOC API version: 1.0.0 servers: - url: https://siloc.sandbox.lerian.net security: [] paths: /api/v1/siloc/outbound/deposit-requests: post: tags: - Collateral summary: Request a collateral deposit the câmara already accepted description: >- Issues a LDL1003 to the Câmara LDL on behalf of an Entidade Responsável (Catálogo de Serviços do SFN v5.13, Vol II).
