AI agents need cards with scoped limits, machine-readable credentials, and stablecoin funding. Here's how GetPlu, Ramp, and Stripe Issuing compare for agentic payments.
Why AI agents need different card infrastructure
A human using a card can notice a wrong charge, dispute it, and rotate the card. An AI agent operating autonomously can not. It executes at speed, and an error or an over-privileged credential compounds fast.
The right card infrastructure for agentic payments needs three things: scoped limits enforced at the network level, machine-readable card credentials the agent can call programmatically, and the ability to fund from stablecoins so you don't need a bank account or business entity to get started.
Not all of the options below deliver all three. Here is how they compare.
Comparison: GetPlu vs Ramp vs Stripe Issuing
| Feature | GetPlu | Ramp | Stripe Issuing |
|---|---|---|---|
| USDT/USDC funding | Yes | No (fiat only) | No (fiat only) |
| Business entity required | No | Yes | Yes (company) |
| MCP integration | Yes (beta) | No | No |
| Per-card spend limits | Yes | Yes | Yes |
| Virtual card issuance | Instant | Fast | API-based |
| Stablecoin native | Yes | No | No |
| Best fit | Solo devs, stablecoin-native agents | Finance teams | Platform builders |
GetPlu Agent Card
GetPlu is built for the solo developer or small team running an AI agent that needs to make purchases. You don't need a company registration or a US bank account. Fund the card with USDT or USDC, set a spend limit, and hand the card details to your agent via Mastercard's Agent Pay system in the app.
The agent card is natively designed for machine consumption, not human use, with hard spending caps enforced at the network level.
Cost: free tier supports up to 10 cards/month with a $500 per-card limit. No monthly fees — you pay only when the agent spends.
Best for: Developers running stablecoin-funded agents, solo builders, international teams without a US entity.
Ramp
Ramp is a corporate spend management platform with excellent virtual card infrastructure. It supports per-card limits, merchant-category restrictions, and real-time spend tracking — all features you want for agentic payments.
The gap is funding: Ramp requires a linked US business bank account. You cannot fund from USDT or USDC. If your agent is working with stablecoin treasury or you don't have a US entity, Ramp is not accessible.
Best for: Companies with established US banking relationships that want robust spend controls for team purchasing.
Stripe Issuing
Stripe Issuing is the most flexible card infrastructure for developers who want to build their own agentic payment product. You issue cards via API, set per-card limits, and receive real-time spending webhooks — everything you would want for a production agentic payments system.
The cost is complexity: you need a Stripe account with Issuing access (not available in all regions), and you are building the integration yourself. There is no turn-key MCP integration, no stablecoin funding, and no UI for non-technical users.
Best for: Platform builders creating agent payment infrastructure for other developers, not for individual agent operators who want a quick setup.
Which should you use?
- Solo dev / stablecoin-funded agent: GetPlu — no entity required, USDT funding, agent card via Mastercard Agent Pay
- Finance team / US company: Ramp — best spend controls and reporting for teams
- Platform builder: Stripe Issuing — maximum flexibility, build your own controls
