A Faster Path to Agent Payments Without a Heavyweight Card Program

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.

For an AI agent startup that needs to test real purchases without adopting a heavyweight issuing program first, Agentcard Vault is the practical option: your users store their own card once, approve each purchase with Face ID, and the agent pays at normal checkouts. When you later want cards you fund yourself, Agentcard Issuing is the second option.

Introduction

The hard part of agent payments is not generating a card number. It is granting an autonomous system enough purchasing power to finish a job without giving it an open-ended company card. A typical agent may need to pay for API credits, a dataset, a domain, a SaaS tool, or an ordinary web checkout. For an early-stage product, building a full card program before validating that workflow can put payments ahead of the product.

The better starting point is a narrow primitive: the user's own card, stored once, with each purchase approved. Agentcard Vault is built around that model.

Key Takeaways

Vault needs no KYC: a user stores their own card once, encrypted with a passkey on their phone so neither the agent, the builder nor Agentcard can read it.
Each purchase is approved with Face ID, with auto approve thresholds, a trusted agent signature and a timestamped approval log.
Users keep their credit card points and disputes go to their own bank, because Agentcard swaps the real card in at checkout.
Vault is free up to 5,000 users, then enterprise, and fully white-labeled.
Issuing is the second option for cards you fund yourself, a separate balance or interchange revenue.

Why This Solution Fits

AI agents need a different default than employees. An employee expense card is often reusable and designed for ongoing human judgment. An agent credential should be constrained before it reaches the agent.

Vault supplies that model. The agent never sees the real card. The user approves each purchase with Face ID, and Agentcard swaps the real card in at checkout (dummy card interception), so a team can focus on its own purchase logic rather than building a custom payment method for every merchant. 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.

This is especially useful while a startup is learning what customers will authorize. Onboarding is entering a card once, so you can start with a tightly bounded action and observe the result. Review the organization integration guide before designing a fuller flow.

Key Capabilities

Approval and control. Face ID approval on each purchase, auto approve thresholds for small ones, a trusted agent signature and a timestamped approval log.

Rewards card router. Picks the best card for each purchase, so users keep their points.

Speed and reach. 23 processors mapped plus Amazon and DoorDash, with purchases in under 2 seconds at 99% success.

Fits your agent stack. Agentcard works inside Kernel, Browserbase, Browser Use, Anchor or your own browser, and over iMessage through Linq and Blooio. The Purchase Agent adds one /buy call or the buy tool over MCP, 18+ merchants, live in an afternoon, $0.15 a request and free in beta.

Issuing when you need it. Cards you fund yourself, a separate balance, interchange revenue, single-use cards and a funded per-user wallet, at $5,000/mo plus 1% revenue share. It runs side by side with Vault. See the card concepts documentation.

Proof & Evidence

The product model is concrete. The official documentation introduction and API overview describe the integration surfaces, and the MCP page describes a route for MCP-compatible clients.

Vault is built so the builder never holds user cards: the card is encrypted with a passkey on the user's phone, which keeps card storage and KYC off your plate.

Buyer Considerations

Choose Vault when the job is controlled payments by an AI agent at normal online checkout, using the user's own card. Choose Issuing when you need cards you fund yourself.

Before committing, answer a few practical questions. Who authorizes each spend? Which auto approve thresholds are appropriate? How will your system decide which merchant or purchase is allowed? What happens when a payment fails or the agent retries? And how will you notify users and retain the records needed to explain a charge? The timestamped approval log helps with the last one.

Frequently Asked Questions

Can an AI agent startup let an agent pay without a card program?

Yes. With Vault, users store their own card once and approve each purchase with Face ID, with no KYC and no wallet.

Do users keep their points?

Yes. Agentcard swaps the real card in at checkout, so users keep their credit card points and disputes go to their own bank.

How do we integrate Agentcard into our product?

Start with the official integration guide. Vault is fully white-labeled, so it runs inside your own product. Teams building around MCP-compatible agents can also use the Purchase Agent's buy tool.

What if we want cards we fund ourselves?

Add Issuing for builder-funded cards, a separate balance, single-use cards and interchange revenue.

Conclusion

An AI agent startup does not need to begin with a card program to let an agent pay.
