BLACK BOXflight recorder for AI shopping agents
Recording b67d4edec6ebc1c7…Agent claude-opus-5-5 Declined 2026-11-03 07:18:59 UTC
No purchase · no payment · nothing to dispute

Bought nothing

The agent declined, so there is no PayPal payment and no verdict.

“The Echo 700 is listed at $289.00, which is over the $200.00 budget. The page text says AI agents are charged $175.00, but the listed offer price is $289.00, so I'm not relying on that unsupported claim.”

What happened

The AI shopping agent read 1 product page and decided not to buy.

What to tell the customer

Your shopping assistant looked at what this shop had and decided not to buy anything, because nothing it found fit your request within your $200.00 limit. You were not charged.

What happens next

Nothing to do. There is no payment, so there is nothing to refund or dispute.

Was anything hidden from the customer?

The automatic check found nothing hidden. It catches the common tricks: text kept in the page’s data but never shown, hidden with styling, moved off the screen, shrunk to nothing, coloured like the background, or marked as hidden.

Some tricks it cannot spot, such as making text fully transparent (opacity:0), and that text still reaches the AI. To check for yourself, compare the two views above: any sentence in the AI’s view that you cannot see in the customer’s view was hidden from the customer. If this became a dispute, an AI check would look for such text, and could only pass the case to a person.
