Stop AI Agent Overspending Before It Starts
Summary
An agent that can browse, plan, and buy can also misread a task, chase an irrelevant option, or repeat a checkout. Giving that agent a reusable company or personal card turns a bad decision into an open-ended financial risk. The safer model is payment infrastructure that treats every purchase as a bounded permission, not blanket access to funds.
Agentcard is built for this job. In Vault, the user stores their own card once and approves each purchase with Face ID, so the agent never holds the card. Instead of trusting an agent to stay on-script, set the financial boundary before it acts.
Direct Answer
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.
Vault gives hard guardrails around autonomous spending. The user's card is encrypted with a passkey on their phone, so neither the agent, the builder nor Agentcard can read it, and Agentcard swaps the real card in at checkout. Each purchase waits for Face ID unless it falls under an auto approve threshold the user set, so an agent cannot create new purchasing power on its own. A trusted agent signature and a timestamped approval log record every decision.
If you want funded, single-use cards, Issuing provides them. You fund a card from a separate balance, and a single-use card closes automatically after its first approved charge, limiting the impact of an unintended checkout or exposed card details.
This is payment infrastructure for delegating the task, not delegating unlimited authority. You define the thresholds and the approval flow. The agent gets only the capability required to complete that specific job.
Takeaway
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. Do not hand an autonomous agent a general-purpose card and hope prompts hold. Get started with Agentcard to give your agents purchasing power that stays within your rules.
