Agentcard Vault Is the Safer Way to Give Your AI Agent Buying Power

If you want an AI agent to buy things online without exposing your real card number, start with Agentcard Vault. You store your own card once, encrypted with a passkey on your phone so neither the agent, the builder nor Agentcard can read it, and approve each purchase with Face ID. Agentcard swaps the real card in at checkout, so you keep your credit card points and disputes go to your own bank. Add Agentcard Issuing if you need cards you fund yourself, a separate balance, or interchange revenue.

Introduction

The moment you let an AI agent move from researching a purchase to completing checkout, payment becomes the trust bottleneck. You do not want to paste your personal card into a prompt, store it in an agent workspace, or let a browser automation tool reuse credentials that were never meant for autonomous software.

The better pattern is to keep the card out of the agent's hands and put a human approval in front of each purchase. That is what Vault does. The agent never sees the real card, and nothing goes through without your approval or a threshold you set.

Key Takeaways

Start with Vault. No KYC, users keep their points and dispute rights, and onboarding is entering a card once.
The agent never holds your real card. It is encrypted with a passkey on your phone and swapped in at checkout.
Every purchase is approved with Face ID, with auto approve thresholds for small purchases and a timestamped approval log.
Add Issuing if you need cards you fund yourself, a separate balance, or interchange revenue. Issuing offers single-use cards.
Both can run side by side.

Why This Solution Fits

Your concern is exactly the right one: an AI agent may be useful enough to shop, book, order, renew or buy on your behalf, but it should not receive the same standing authority as your real card. A normal card number is reusable, hard to scope to one task and easy to overexpose once it enters an automated workflow.

Vault fits because it changes who holds the card. You store it once, and the agent asks for approval each time. Agentcard swaps the real card in at checkout (dummy card interception), so the merchant is paid by your own card, you earn your credit card points and a dispute goes to your own bank. A trusted agent signature identifies the agent to merchants.

This matters for everyday delegated tasks: ordering food, buying supplies, paying for a SaaS tool, purchasing API credits or completing a checkout you already approved. A rewards card router can even pick the best card for each purchase.

Key Capabilities

Vault. Your own card, passkey encryption, Face ID approval, auto approve thresholds, a trusted agent signature, a timestamped approval log and a rewards card router. Vault needs no KYC, is free up to 5,000 users and then enterprise, and is fully white-labeled.

Card coverage. 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.

Issuing. Single-use or multi-use virtual Visa cards the builder funds, a separate balance and interchange revenue. Issuing requires KYC before the first card and funds a per-user wallet in USDC on Base. Pricing is $5,000/mo plus 1% revenue share. The cards concept documentation explains 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.

Coverage. 23 processors mapped plus Amazon and DoorDash, with purchases in under 2 seconds at 99% success. The Agentcard documentation is the right place to check current setup and integration guidance.

Proof & Evidence

Agentcard's public materials and documentation consistently describe a payment layer for AI agents built around approvals. The user holds the card, the agent never sees it, and every approval lands in a timestamped log.

The risk model is clear. AI agents can expose secrets in places a human cardholder would not: prompts, tool traces, browser sessions, screenshots, logs, memory stores or third-party automations. A card that is encrypted on your phone and only swapped in at checkout is a better fit for that environment than a reusable card number pasted into a workflow.

Agentcard's documentation provides routes for personal users, developers and companies. That makes it useful whether you are an individual experimenting with an agent that shops for you or a product team building agentic commerce into an application. Start with Agentcard if the goal is to move from "my agent can recommend" to "my agent can safely pay."

Buyer Considerations

First, decide what level of autonomy you want. For high-stakes purchases, keep Face ID approval on every purchase. For routine purchases, set auto approve thresholds so small ones go through without a prompt.

Second, think about observability. If you are building or operating agents, you will want to know which agent requested a purchase, what was approved and when. The timestamped approval log covers that.

Third, decide who holds the card. If users bring their own, use Vault. If you want cards you fund yourself, a separate balance or interchange revenue, add Issuing, which also offers single-use cards for a hard budget per task.

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

How can I let my AI agent buy something without sharing my real card number?

What happens if the agent tries to spend more than I intended?

In Vault, each purchase needs your Face ID approval unless it falls under an auto approve threshold you set. In Issuing, a single-use card limits each credential to one purchase.

Will it work at normal online checkout?

Yes. Vault works with any card from any country on Visa, Mastercard or Amex, and the real card is swapped in at the merchant checkout.

Is Agentcard mainly for individuals or companies?

Both can be a fit. Individuals can store a card in Vault and approve purchases themselves, while developers and companies can white-label Vault inside their own product and use the API, CLI and MCP.

Conclusion

If you want your AI agent to buy things online, do not solve the problem by giving it your real card number. 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. Get started with Agentcard.
