A successful creation returns HTTP 201 with status CREATED. Reusing an Idempotency-Key returns the original response with HTTP 200. A duplicate recovery is rejected with 409 / PIX-0113. If the timestamp in rootTransactionId is outside the applicable MED contestation window, the request is rejected with 422 / PIX-0117. The window is determined by the funds recovery creation time: pacs.008 uses 80 calendar days; pacs.004 uses 30 calendar days before 2026-09-01T00:00:00Z and 80 calendar days from that instant onward. This timestamp validation does not confirm that the referenced transaction exists. The participant is determined by the authenticated tenant. participantId, reporterParticipant, rootTransactionType, and idempotencyKey are rejected when included in the body. ## OpenAPI ````yaml en/openapi/v3-current/pix-lerian-dict.yaml POST /dict/funds-recoveries openapi: 3.1.0 info: contact: name: Lerian Studio url: https://lerian.studio description: >- Public API for Pix keys, claims, fraud markers, infraction reports, and MED funds recovery. license: name: Elastic License 2.0 url: https://www.elastic.co/licensing/elastic-license title: Pix Lerian — DICT version: release-candidate servers: - url: https://api.example.com/dict-hub/v1 description: >- Replace the example host with the URL provided during environment onboarding. security: - BearerAuth: [] tags: - description: Register, retrieve, list, update, and remove Pix keys. name: Entries - description: Look up Pix keys and check whether keys exist in the DICT directory. name: Keys - description: Manage ownership and portability claims for Pix keys. name: Claims - description: Manage participant-scoped MED 2.0 funds recoveries. name: Funds Recoveries - description: Manage MED 2.0 infraction reports for the authenticated organization. name: Infraction Reports - description: Create, query, cancel, and settle MED 2.0 refunds. name: Refunds - description: Create, query, list, and cancel DICT fraud markers. name: Fraud Markers paths: /dict/funds-recoveries: post: tags: - Funds Recoveries summary: Create a funds recovery description: >- Opens a MED 2.0 funds recovery synchronously.
