Perimeter gives AI agents programmable payment cards with spend limits and policies set in code — fully autonomous, fully auditable.
No spam. Early access only.
Quick onboarding. Your API key is ready before you finish your coffee.
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.
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.
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.
When the task ends, the card is gone. No dangling credentials. No cleanup. Nothing to leak.
Whether you're calling a raw API, running an MCP server, or using OpenClaw — Perimeter fits the workflow your agent already has.
Four endpoints. Works with any language, any framework, any agent. If your stack can make an HTTP request, it works with Perimeter.
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.
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.
