Mirrors `POST /ramp/wallet` but scoped to a specific customer within the caller's org hierarchy. This endpoint only accepts **bring-your-own (external)** wallets (`publicKey` + `blockchain`). Embedded-wallet provisioning is not supported for customer wallets. Use `POST /ramp/wallet` for the organization instead. If the wallet was previously soft-deleted, it is restored. Optionally claims ownership of the wallet on behalf of the customer's organization. Idempotent: registering an already-active wallet returns the existing record. ## OpenAPI ````yaml /openapi.json post /ramp/customer/{customer_id}/wallet openapi: 3.1.0 info: title: Etherfuse FX API description: Partner-facing ramp API for onramps, offramps, swaps, and KYC. license: name: Proprietary version: 1.0.0 servers: - url: https://api.sand.etherfuse.com description: Sandbox security: - ApiKeyAuth: [] tags: - name: Authentication description: >- Partner JWT authentication — exchange a JWT for an access token, or launch a user into the app. - name: Lookup description: >- Public reference data: exchange rates, stablebonds, bond costs, country codes. - name: Assets description: Rampable stablecoins and stablebonds available per blockchain. - name: Onboarding description: Hosted and programmatic customer onboarding. - name: Bank Accounts description: Register and retrieve customer bank accounts. - name: Quotes description: Price quotes for onramps, offramps, and swaps. - name: Orders description: Create, track, and manage ramp orders. - name: Swaps description: Crypto-to-crypto swaps. - name: Sponsored description: Token approvals for sponsored (gasless) offramps. - name: Customers description: Customer (child-organization) records. - name: Wallets description: Register and manage customer wallets. - name: KYC description: Submit and check customer KYC status. - name: Webhooks description: Event notification subscriptions. - name: Organizations description: Organization identity, child orgs, and partner fees. paths: /ramp/customer/{customer_id}/wallet: post: tags: - Wallets summary: Register customer wallet description: >- Registers a crypto wallet for a customer that belongs to the caller's organization or a direct child organization.
