Exact item confirmation
Check product id, variant, quantity, merchant, and final price together.
Shopping agent checkout
Catch the wrong cart before checkout.
Shopping agents turn discovery into payment. Featherlane AI checks the item, variant, merchant, price, and retry context before a one-click or agent-fired checkout completes.
Failure modes
Tiny product mistakes turn into payment disputes.
- The agent buys the wrong size, color, or variant.
- The product price is stale by the time checkout starts.
- A multi-merchant basket partially fails and retries the wrong item.
- A resent checkout link creates a duplicate charge.

Questions
What teams ask before they wire it in.
Is this a checkout provider?
No. Featherlane AI checks the proposed checkout action before your app sends it to the checkout or payment provider.
Can it handle multi-merchant carts?
The event shape can include action metadata for each checkout step so your app can hold or block risky partial failures.
Ship the check
Put a effect between the agent and the action.
Bring a real checkout, refund, booking, or invoice flow. We will map the exact pre-action check and the audit record it should leave behind.
