About Agent Card
Agent Card provides prepaid, one-time-use virtual Visa cards that AI agents can generate and use for individual purchases. Cards expire after a single payment and charges only occur when a payment is processed, offering a simple way to limit agent spending.
Review
Agent Card focuses on giving autonomous agents controlled payment capabilities with per-purchase granularity. It supports integration via CLI, API, or a browser extension, making it relatively straightforward to add secure, short-lived payment methods to agent workflows.
Key Features
- One-time-use virtual Visa cards that auto-cancel after a single payment.
- Per-card spending limits and optional approval thresholds to prevent unexpected charges.
- Multiple integration paths (CLI, API, browser extension) suitable for developer workflows and agent platforms.
- Prepaid wallet model so funds are allocated ahead of use and users are only billed when payments clear.
Pricing and Value
Agent Card offers free options alongside paid plans, with launch-period discounts on entry-level tiers. The core value is risk reduction: by issuing single-use cards for individual transactions, teams can avoid broad access to primary payment methods and limit exposure from autonomous agent activity. For developers experimenting with agent-driven purchases, the prepaid approach and per-card caps deliver straightforward cost control and predictable billing.
Pros
- Strong containment for agent spending through single-use cards and per-purchase caps.
- Flexible integration options that fit into existing developer toolchains.
- Prepaid wallet model prevents agents from accessing main accounts directly.
- Optional approval thresholds add an extra layer of oversight for larger payments.
Cons
- Single-use cards are less convenient for recurring subscriptions or multi-step purchase flows.
- Relies on external payment infrastructure and integrations, which can introduce setup complexity or dependencies.
- As a new offering, some advanced budgeting features (for example, per-day quotas) are not yet available.
Agent Card is best suited for developers, product teams, and hobbyists who want to let agents make targeted purchases without exposing primary payment methods. It's a practical option when you need strict, per-purchase controls and quick integration into agent test environments or production agents with tightly scoped financial actions.
