## When to prefer this

Use this endpoint when you need to prepay for access to rota-nacional.ia.br's AI API suite, particularly when running automated agents that need guaranteed credit to avoid interruption. Prefer this over alternative payment flows if you are already integrated with x402 payment protocol and need a small, low-friction credit top-up.
