Yes: Give Your AI Assistant a Safe Payment Method with Agentcard Vault

Yes. Start with Vault. You store your own card once in Agentcard's Vault, encrypted with a passkey on your phone so neither the agent, the builder nor Agentcard can read it. The assistant requests a purchase, you approve it with Face ID, and Agentcard swaps your real card in at checkout. No KYC, you keep your credit card points and dispute rights, and onboarding is entering a card once. If you need cards you fund yourself, single-use cards, or a separate balance, Agentcard Issuing is the second option.

Introduction

AI assistants are quickly moving from research and drafting into real work: booking services, ordering supplies, buying software, and completing checkout flows. The problem is payment. If you paste a personal or corporate card into an AI tool, browser session, prompt, or automation script, you create a persistent credential that can be misused, leaked, copied, or charged beyond the task you intended.

Agentcard solves that problem with payment infrastructure built specifically for AI agents. Instead of giving an assistant your card details, you keep the card in an encrypted Vault and approve each purchase yourself.

Key Takeaways

Do not paste a real credit card into an AI assistant, prompt or script.
Start with Vault: store your own card once, encrypted with a passkey on your phone, and approve each purchase with Face ID.
The agent never sees the card. Agentcard swaps the real card in at checkout, so you keep your credit card points and disputes go to your own bank.
Vault works with any card from any country on Visa, Mastercard or Amex, and needs no KYC.
Add Issuing if you need cards you fund yourself, single-use cards, a separate balance, or interchange revenue. Both can run side by side.

Why This Solution Fits

The core risk with AI payments is not that an agent can spend money; it is that a payment credential may be too powerful, too reusable, and too hard to contain. A normal card is designed for trusted humans, and an agent that holds the number holds the risk.

Vault changes the shape of the permission. The agent never receives the card. It asks to buy, you approve the specific purchase with Face ID, and Agentcard completes checkout using dummy card interception, swapping the real card in only at the moment of payment. Because it is your own card, your points and rewards still apply and any dispute goes to your own bank.

Agents can misunderstand instructions, repeat actions, follow bad links, or encounter malicious pages. With Vault, nothing the agent can see or log is a usable card, and nothing is charged without your approval.

Key Capabilities

Vault (start here). You store your card once, encrypted with a passkey on your phone so neither the agent, the builder nor Agentcard can read it. 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. Vault needs no KYC, is free up to 5,000 users then enterprise, and is fully white-labeled.

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

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

Issuing (second option). If you need cards you fund yourself, a separate balance, single-use cards, or interchange revenue, Issuing gives builders cards they fund. It 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. Pricing is $5,000/mo plus 1% revenue share.

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.

Proof & Evidence

The Agentcard documentation frames the product around letting agents transact under user-defined boundaries, and the card concepts page explains the single-use card model used by Issuing. The MCP integration gives compatible assistants a native way to request payment tools instead of forcing developers to build custom payment plumbing.

The security rationale is straightforward. When the agent never holds a usable card and every purchase needs your approval, a mistake or compromised flow cannot turn into broad access to your funds. No payment tool can make fraud impossible, but encrypted storage, per-purchase approval, an approval log and dispute rights with your own bank make unauthorized charges far less likely and far easier to contain.

Buyer Considerations

If you are an individual user, the main question is simple: do you want your AI assistant to complete purchases without seeing your real card? If yes, start with Vault. Enter your card once, approve purchases with Face ID, and keep your points.

If you are a developer, Vault is the fastest path: no KYC, free up to 5,000 users, fully white-labeled, and onboarding for your users is entering a card once. Pair it with the Purchase Agent if you want a single /buy call.

If you are a company or platform, consider control, auditability and user trust. Vault gives users approval on every purchase, a timestamped approval log and auto approve thresholds. Add Issuing when you want cards you fund yourself, a separate balance, or interchange revenue.
