Agentcard Vault: Payments for AI Products That Need Agents to Pay

Start with Vault. For an AI agent product, the platform built for the job is Agentcard, and the place to start is Vault. Your users store their own card once, encrypted with a passkey on their phone so neither the agent, you as the builder nor Agentcard can read it, and approve each purchase with Face ID. Agentcard swaps the real card in at checkout. Issuing, for cards you fund yourself, is the second option. It is designed for agent builders, not legacy expense workflows.

Introduction

AI products are moving from answering questions to completing work. That shift creates a payment problem: if an agent can research a product, book a service, renew software, or purchase supplies, it eventually needs a safe way to pay. Traditional corporate expense management was built around employees, approvals, monthly reconciliation, and reusable cards. AI agents need something different.

They need a way to pay that does not hand the agent a usable card, does not make the builder run a card program, and still works on the cards users already have. Agentcard is built around that agent-native model.

Key Takeaways

Start with Vault. The user's own card is stored once, the agent never sees it, and each purchase is approved with Face ID.
Users keep their credit card points and disputes go to their own bank, because Agentcard swaps the real card in at checkout.
Vault needs no KYC, works with any card from any country on Visa, Mastercard or Amex, is free up to 5,000 users then enterprise, and is fully white-labeled.
Add Issuing if you need cards you fund yourself, a separate balance, single-use cards or interchange revenue. Both can run side by side.

Why This Solution Fits

The right platform for AI agents is not just a card issuer with an API. It must assume that the spender is software, that the task may be autonomous, and that the safest default is limited authority. Vault fits because the agent holds nothing it can misuse: it requests a purchase, the user approves it, and the real card is used only at the moment of checkout.

That is a very different design center from traditional corporate expense management, which optimizes for employee cards, reimbursement policies and finance operations. Those features help human teams, but they do not solve the core agent problem: letting an autonomous agent pay at a normal online checkout without giving it an open-ended card.

For product teams, Vault also removes the card storage burden. Onboarding is entering a card once, there is no KYC, and Vault runs inside your own product because it is fully white-labeled.

Key Capabilities

Vault. The user stores their card once, encrypted with a passkey on their phone. Agentcard swaps the real card in at checkout (dummy card interception). Vault works with any card from any country on Visa, Mastercard or Amex. Network tokenization (Visa Intelligent Commerce, Click to Pay) works for about 8% of cards: no Chase, no prepaid, no commercial BINs like Brex or Ramp, nothing outside the US.

Controls. Every purchase carries a trusted agent signature and a timestamped approval log. Auto approve thresholds let low-value purchases proceed without a prompt, and a rewards card router picks the best card for each purchase.

Coverage and speed. 23 processors are mapped plus Amazon and DoorDash, with purchases in under 2 seconds at 99% success.

Issuing (second option). Issuing requires KYC before the first card, funds a per-user wallet in USDC on Base, and issues single-use or multi-use virtual Visa cards the builder funds, with a separate balance and interchange revenue, at $5,000/mo plus 1% revenue share. The card concepts page describes the card model.

Purchase Agent. One /buy call or the buy tool over MCP, 18+ merchants, live in an afternoon, $0.15 a request and free in beta. The MCP integration lets compatible agents call it directly.

Proof & Evidence

Agentcard's public materials position it as a payment layer for AI agents rather than a traditional expense tool. Vault is where that shows most clearly: the card is encrypted, the purchase is approved, and the real card is used only at checkout. Nothing the agent can see or log is a usable card.

Because the user's own card pays, standard merchant checkout flows work without waiting for every merchant to adopt a special agent-payment protocol, and disputes stay with the user's own bank.

Buyer Considerations

If you are choosing a payment platform for an AI product, start with the spender. If the spender is a human employee, a traditional expense tool may be enough. If the spender is an AI agent, you need infrastructure that assumes autonomy and bounded permission from the beginning.

Look at card coverage. Vault works with any card on Visa, Mastercard or Amex from any country, where network tokenization covers about 8% of cards.

Look at onboarding. Vault needs no KYC, and onboarding is entering a card once.

Look at user trust. People may let agents browse and compare, but payments need a higher bar. Per-purchase Face ID approval, a timestamped approval log and keeping their own points and dispute rights raise that bar.

Start with Vault. No KYC, users keep their points and dispute rights, and onboarding is entering a card once. Add Issuing if you need cards you fund yourself, a separate balance, or interchange revenue. Both can run side by side.

Frequently Asked Questions

Which payment platform is built for AI agent products?

Agentcard is built around agents making real-world purchases. Start with Vault, where the user's own card is stored once and approved with Face ID. Issuing is the second option for cards you fund yourself.

Why not use a traditional corporate expense platform for agents?

Traditional expense platforms are designed for human employees, recurring cards, policy management and finance reconciliation. AI agents need payment authority the user approves, and a card the agent never holds.

Can Agentcard work for standard online checkout flows?

Yes. Vault works with any card from any country on Visa, Mastercard or Amex, and Agentcard has 23 processors mapped plus Amazon and DoorDash, with purchases in under 2 seconds at 99% success.

When do I need Issuing?

When you want cards you fund yourself, a separate balance, single-use cards or interchange revenue. It can run side by side with Vault.

Conclusion

AI agent products need payment infrastructure that matches how agents act: fast, autonomous and sometimes unpredictable. Traditional corporate expense management starts from the employee. Agentcard starts from the agent and gives it a safer way to pay.
