Four Real x402 Settlements: What Actually Happens When an Agent Pays for a GPU

We ran 4 real x402 settlements tonight against our production endpoint. Sharing the raw data, successes and one rejection included, because this community tends to want the receipts, not the summary.

What we ran

Each transaction is a genuine on-chain USDC payment on Base, confirmed by a real transaction hash and a matching Stripe PaymentIntent. Endpoint: kilawattcloud.dev/api/public/x402/exec.

Run	GPU	Billed	Notes
1	nvidia-a10	$0.0400	Baseline settlement
2	nvidia-a10	$0.0400	Repeat run, confirms repeatability
3	nvidia-a10	$0.0400	Third consecutive success
4	h100	$0.0408	Failed over from 2 nodes before landing on a 3rd

The interesting one

Run 4: the agent requested an h100. First candidate node (US-East-04) didn't complete the assignment. Second (US-East-09), same. System automatically routed to a third node (US-West-07), which succeeded.
