01

Sign up. Get your key.

Quick onboarding. Your API key is ready before you finish your coffee.

02

Load your account.

Top up with a fixed amount. That balance is the hard ceiling — your agents can never spend more than what's there. No credit. No overdraft.

03

Create a card for your agent.

One API call. Pass in your agent ID, a spend limit, and merchant rules. Get back a real Visa card number, CVV, and expiry. Hand it to your agent.

04

Your agent acts. You watch.

Your agent uses the card to complete its task. Every transaction appears in your dashboard in real time — merchant, amount, which agent, which policy rule fired.

05

Card destroys itself.

When the task ends, the card is gone. No dangling credentials. No cleanup. Nothing to leak.

// works with your stack

Your agent already knows
how to use it.

Whether you're calling a raw API, running an MCP server, or using OpenClaw — Perimeter fits the workflow your agent already has.

API

Raw API. Zero lock-in.

Four endpoints. Works with any language, any framework, any agent. If your stack can make an HTTP request, it works with Perimeter.

MCP

Native MCP server.

One config block and you're connected. Any MCP-compatible runtime — Claude, Cursor, or your own — gets instant access to Perimeter's full card and spend controls.

RECOMMENDED🦞 OPENCLAW

One command. Your agent can pay.

Install the Perimeter skill from ClawHub and your OpenClaw agent gains the ability to create cards, set limits, and make purchases — completely autonomously, no integration code required.

The only skill on ClawHub that lets your agent spend real money.
Don't see your framework? The REST API works with everything.
