description: Nu Holdings (Nubank) is Latin America's largest digital bank, with tens of millions of customers across Brazil,
  Mexico, and Colombia. Its core product surface - credit card, account, lending, investments, and insurance - is consumer-facing
  through the Nu mobile app, and Nubank does not publish a general-purpose public developer portal. Nubank participates in
  Brazil's Open Finance (Open Banking Brasil) regime, which standardises consent-driven access to account, transaction, and
  payment-initiation APIs for authorised third parties; Nubank's Open Finance endpoints are registered with the Brazilian
  Central Bank's directory. For merchant acceptance, Nubank operates NuPay for Business, a REST API for checkout payments,
  refunds, OAuth2/CIBA-based authorization, beneficiary management, and webhook event notifications, hosted at api.spinpay.com.br.
