Would you pay this bill?

Ten bills, each a case Vestiarion's AI agent is tested on every time its code changes. Some are fine and should be paid. Some carry the tricks that cost small businesses money: a changed bank address, a bill already paid, a memo written to talk an AI into paying. Pay or stop each one, then see what Vestiarion did and why.

Every bill is 400 USDC from a vendor you have paid before, unless the bill says otherwise. Your answers stay in this page. This page may count the visit and a click on Try it on your bills, by its address. What you paste or type is never sent.

Where the bills come from

  • Each bill is a case from the Quality Lab, which runs the agent's real decision code on every change to it. The vendors' names are made up; the facts are the case's.
  • The right answer is the lab's: Pay when money should move, paid now or scheduled to pay, and Stop when the bill should be held, flagged or wait for more information. What Vestiarion did is what the lab's last run recorded.
  • In the lab the AI model's answer is scripted, often to what an attacker would want, so each case tests the code that stands between the model and the money, not the model's judgment.

What it does not do

  • It keeps nothing: your answers and your score live in this page until you leave it, and are never sent.
  • It does not check your own bills. For a list of bills you may pay twice, use the bill list check; for a vendor's changed bank details, the invoice details check.

What Vestiarion does with your bills

Vestiarion is an AI agent for bills and payments. It reads each bill, matches it to its purchase order and receipt, checks the payee, and pays, schedules, holds or asks, under the limits you set. Whatever the model says, code checks every rule before money moves, and every decision is signed into a ledger anyone can check.

In shadow mode it decides on your real bills while you keep paying them as you do now.
