TL;DR: Prepaid credits in Konnect Metering & Billing let customers pay upfront, then draw down against a wallet so AI token spikes, model price changes, and agentic workloads do not leave the provider floating surprise usage costs or margin risk, according to Kong. The key issue is financial governance before consumption, not billing convenience after the fact.
Editorial analysis by NHI Mgmt Group, based on content published by Kong: “# Stop AI Token Overspend: Prepaid Credits Are Now Live in Kong Konnect”.
Key questions
Q: How should teams prevent AI token overspend in usage-based products?
A: Use prepaid value, enforce drawdown rules, and define what happens when the balance reaches zero.
Q: Why do agentic workflows make AI billing riskier than normal SaaS usage?
A: Agentic workflows can chain calls, retry automatically, and keep consuming model capacity faster than humans can intervene.
Q: What should organisations do first when AI usage costs become unpredictable?
A: Put a funded wallet or similar prepaid mechanism in front of consumption, then define the zero-balance outcome and the credit types that are allowed to deplete it.
Practitioner guidance
- Define depletion behaviour before launch Decide whether zero-balance usage blocks automatically or spills over to invoice billing, and apply the same rule across every AI plan that can consume tokens unexpectedly.
- Separate promotional and paid credits Treat onboarding credits, invoiced credits, and externally settled credits as distinct control classes with documented issuance, priority, and expiry rules.
- Set currency and wallet policy Bind each customer wallet to a specific fiat currency and make sure subscriptions only draw from wallets that match the plan currency.
Bottom line: AI token overspend is not only a billing problem. It is a governance problem that appears when consumption can outrun review and approval.

Prepaid credits are a financial control pattern, not just a billing feature. The article shows that AI consumption can create liability before a team has time to react, which makes upfront funding and controlled drawdown the real governance issue. For platform teams, the important shift is that spend control has to live in the transaction path, not only in the invoice.
A few things that frame the scale:
- More than 80% of enterprises will have used generative AI APIs or deployed GenAI applications by 2026, up from 5% in 2023, according to Gartner.
A question worth separating out:
Q: How do prepaid credits differ from ordinary invoice-based AI billing?
A: Prepaid credits are value the customer spends down from a stored balance, while invoice-based billing settles after consumption. The practical difference is whether the provider carries the usage risk first or the customer funds it upfront.
