This reflects the real sequential client flow used by DUX and corrects the main mismatches in the published docs: POST /auth authenticates with X-Client-Id and X-Client-Secret headers, POST /onboarding/{customer_id}/create-bank-account is the active bank-account route, POST /due-diligence/init returns a due_diligence_id plus contracts_preview while upload URLs are requested separately via POST /due-diligence/{due_diligence_id}/uploads, and due diligence signature confirmation is not a client API step because it is performed by the signer through an emailed link outside the integrator flow. servers: - url: https://api.sandbox.svrn.digital description: Sandbox - url: https://api.svrn.digital description: Production security: - bearerAuth: [] tags: - name: 01 Authentication description: Bearer token issuance for client integrations. - name: 02 Onboarding description: >- Customer onboarding, listing, verification resumption, and artist PIX registration. - name: 03 Due Diligence description: >- Case creation, file upload URL issuance, offer publication, and status polling.
