Arkin sits between your AI agents and their financial tools. Every payment is evaluated against your policy — and signed to a tamper-evident audit log — before it executes.
As agents take on more autonomy, the blast radius of a mistake — or a prompt injection — grows with it.
Six layers sit between an agent's intent and a dollar leaving the account. Arkin is the policy layer — the one place every action can be intercepted, evaluated, and recorded before it executes.
Arkin reads the intent behind a policy, not just its wording. A transaction can satisfy every literal clause and still betray what the rule was written to protect. Arkin closes that gap.
Built for the people who have to answer for what the agent did — not the people who built it.
Wrap any tool function with @arkin_tool and Arkin intercepts every call. No agent-side changes; no model retraining.
from arkin import arkin_tool @arkin_tool def pay_vendor(vendor: str, amount: float): # your existing tool — unchanged return stripe.transfers.create( amount=int(amount * 100), currency="usd", destination=vendor, )
