Managing OpenAI API billing can be complex for businesses with multiple projects or teams. DogPay offers a practical solution with virtual cards that can be used as a dedicated payment method for your OpenAI account. By creating a virtual card linked to a specific API key or project, you can set spending limits and track usage per card. DogPay supports global accounts, allowing you to fund the card via stablecoin settlement, which can simplify cross-border payments and reduce currency conversion fees. The card works wherever OpenAI accepts major card networks, so you can use it as the primary billing method. While DogPay does not guarantee uninterrupted API access or eliminate all failed payments, it provides a structured way to allocate budget, monitor costs in real time, and control spending across teams. For businesses scaling AI operations, DogPay's wallet and payment infrastructure offer a flexible approach to API expense management.
