Asks which assets the Câmara LDL accepts as collateral and at what prices (Vol II, Evento LDL1013 Descrição). Its answer carries a price per settlement-term indicator, which is what makes it a different question from LDL1015's price history for one asset on one day. 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 (LDL1013R1) arrives asynchronously and is read back with getLDL1013. 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 /pt/openapi/v3-current/siloc.yaml post /api/v1/siloc/outbound/eligible-collateral-queries 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/eligible-collateral-queries: post: tags: - Collateral summary: Query the assets the câmara accepts as collateral description: >- Issues a LDL1013 to the Câmara LDL on behalf of an Entidade Responsável (Catálogo de Serviços do SFN v5.13, Vol II).

Its SHAPE DIFFERS PER CODE because the nine answer legs agree on nothing below the header, and it follows one rule on every code: a leaf element is its trimmed text as a STRING (amounts included, never a number); a Grupo_* element is an ARRAY of objects at every cardinality, one asset included; any other element with children is an OBJECT.
