Levee

Quick answers

What is Levee?

Levee is an authorization layer for AI agent spend where a person approves what an agent may buy, Levee checks every payment against that approval at authorization, and each decision is recorded as tamper-evident evidence.

How is Levee different from card limits and MCC blocks?

Static limits and merchant category blocks cannot express intent about why purchases are allowed. Levee evaluates a signed spend mandate, the platform's policy and the agent's declared purpose together, so payments are approved only when they match what a human actually agreed to.

Where does Levee sit in the payment flow?

Levee runs inside the issuer's real-time authorization path outside the agent itself. The agent cannot skip or override it, and if a decision cannot be made in time the payment fails closed.

Does Levee hold funds or issue cards?

No. Levee works alongside an existing card issuer or payment rail. It decides whether an agent's payment should go through and keeps the proof, while money movement stays with the existing provider.

What happens when a payment falls outside the mandate?

Levee declines it or sends a challenge to the human for quick approval depending on policy. Every outcome comes with a reason code, and organization-level denies cannot be overridden.
