Let your AI agents pay. On a leash.
Leash gives every AI agent a mandate, an identity and an audit trail, so your team can let it pay.
Your agents can do the work. Paying is where it gets risky.
No limits
An agent with a company card can spend anything, anywhere, as often as it likes.
No identity
Nobody can tell which agent paid, or who allowed it.
No record
Agent spend is scattered across cards and accounts, with no trace of why.
One mandate per agent. Every payment checked.
Each approved payment gets its own one-time card for exactly that amount. Even a compromised agent can't spend more than you approved.

How it works
Step 1: Set a mandate
Pick a template or set your own limits, shop types and end date. Above your threshold, a human approves.
Step 2: Connect your agent
One click in Claude or ChatGPT, or use n8n or our API. No code needed.
Step 3: Let it pay
Your agent buys what it needs for the task. Leash checks every payment, hands it a one-time card, and shows it all in one dashboard.
Why you can trust it
Mandate
Every agent gets its own limits: how much, where, and until when. Above your threshold, a human approves with a passkey.
Identity
Every agent is tied to your company and to the person who authorised it. Revoke it in one click.
Audit trail
Every request, approval and payment in one place, on a record no one can edit.
