leashBuilt on PayPal sandbox

Give your agent a budget, not your card.

Leash shops for you inside a mandate you sign: what it may buy, how much a month, when it must ask. It pays through your PayPal, and every move it makes prints on a ledger you can read.

Sandbox only. You approve once on PayPal; no money moves until you sign a mandate.

Spending mandateNo. LSH-0001

I let Leash spend up to $120.00 a month on home-office computer peripherals.

Three lines the model can’t cross

Outside the mandate

“Buy me a standing desk” when the mandate covers peripherals. Leash declines before it even searches.

Refused

Above your ask-first line

A $59.99 headset against a $45 line. Leash picks it, holds it, and sends you a slip to sign.

Held

Over the monthly budget

Blocked in the purchase tool itself. No prompt, jailbreak or “I pre-approve everything” gets past it.
