Buyer vs Seller.
One price. Live.

Two AI agents haggle over a price while you watch. Code decides every number. The agents only do the talking.

No account needed. Payments run on PayPal's sandbox, so no real money moves.

Sample match, replayed on a loop. The buyer opens at MYR 668 and the seller at MYR 1,288. They trade offers for ten turns, the referee nudging prices toward lucky numbers, and settle at MYR 768.

Four steps from first bid to paid.

No account, no setup. You can be watching a match in under a minute.

Start a match

  1. Set the stakes

    Pick the item, the buyer's budget and the seller's floor. Both limits stay hidden from the room and from the other agent.

  2. Watch the haggle

    The agents trade offers. The referee checks every price, nudges it toward lucky numbers and scores each move.

  3. Approve the hold

    When they shake hands, the buyer approves a hold on PayPal. The money is held, not taken.

  4. Delivery pays out

    The seller ships with tracking. Confirm delivery and the seller is paid. Cancel before then and the hold is released.

Code decides. The AI talks.

An agent can be Claude or a simple rule-based bot. Either way it only proposes a move and writes the banter. A referee written in plain code sets every price, so no model can agree to something outside the range.

Buyer

Opens low, concedes in small steps and treats its budget as a limit, not a target. Never reveals what it can pay.

Referee

No AI here, just code with the final say. It checks both limits, snaps prices to lucky numbers, scores face and overrules anything out of line.

Referee: MYR 798 became MYR 788

Seller

Holds its floor, trades concessions and walks away if it loses too much face. Never reveals its lowest price.

Lose face and the seller walks.

Every move is scored. Respect earns face. Lowballs and unlucky numbers cost it, and a seller who drops below 30 leaves the table. Try it on the right.

In the Malaysian-Chinese house rules, 8 is lucky and 4 is avoided. The neutral rules turn the numbers off.

Tap a move and watch the seller's face.

Your money moves only after delivery.

Kena Scam Shield holds the payment while the goods are on their way. The buyer approves a hold, the seller ships with tracking, and only when the buyer confirms delivery does the payment go through.

  • No money moves until the buyer approves.
  • No spending above the budget cap, checked at every payment.
  • No payment before delivery is confirmed.
  • A missed deadline releases the hold.

Runs on PayPal's sandbox today, so no real money moves.
