  title: Okra API
  description: >-
    Specification of the Okra open-finance API. Okra connected applications to
    Nigerian bank accounts to retrieve authentication details, balances,
    transactions, identity, and income, and to initiate bank-to-bank payments.
    All product and query endpoints are POST requests authenticated with a
    Bearer secret key. NOTE: Okra wound down operations in May 2025; endpoints
    are documented as they were publicly published and may no longer be live.
