  title: Tango Fund Account by Credit Card
  summary: Register a credit card, deposit funds onto an account with it, and confirm the deposit settled.
  description: >-
    The end-to-end account funding pattern. The workflow registers a credit card
    to obtain a reusable token, submits a credit card deposit against the target
    account using that token, and then polls the deposit by id to confirm its
    status. Every step spells out its request inline so the flow can be read and
    executed without opening the underlying OpenAPI description. Authentication
    uses the platform's HTTP Basic credentials declared by the basicAuth security
    scheme; those credentials are applied at the transport layer and are not
    request parameters.
