  description: >-
    Marketplace lending origination flow. The workflow fetches the loan offers
    available to a customer, accepts the chosen offer to create a loan,
    disburses the accepted funds, and then reads the customer's loan status to
    confirm an active loan now exists. The offerId is supplied as an input and
    the resulting loanId is threaded into funding. All requests are
    Bearer-authenticated.
