"Four suppliers, real USDC, no accounts: the full results of our x402 GPU test"

Kilawatt Cloud completed a second live verification of its x402 pay-per-job GPU service on October 2, 2026, routing each request to a different supplier — Lambda, Hyperstack, and RunPod — with an autonomous agent paying in USDC on Base and provisioning machines without accounts, API keys, or human intervention. Three of four placements were delivered, totaling $4.88 in real USDC payments; one RunPod request for eight A40 GPUs failed for lack of capacity and was automatically refunded as $0.60 in account credit rather than USDC returned to the wallet. The company notes the test shows suppliers can deliver multi-GPU capacity through the payment flow, but not that any exact configuration is available at any moment.

On October 2, 2026, we completed the second live verification of the x402 pay-per-job service on Kilawatt Cloud. In Wave 1 https://dev.toLINK-TO-YOUR-WAVE-1-POST , every request went to a single supplier. This time we sent each request to a different one, so every supplier could be evaluated on its own. As before: no simulation. An autonomous agent requested GPU capacity, paid in USDC on Base, and received machines with no account, no API key, and no human intervention. We are publishing everything, including the request that failed. Four placements across three additional suppliers: Lambda, Hyperstack, and RunPod. Each request was paid for on Base, ran for ten minutes, and went to the production endpoint. Every payment was a real USDC transaction, $4.88 in total. | | Supplier | Config | GPUs booked | GPUs ready | Time to ready | Paid | Outcome | |---|---|---|---|---|---|---|---| | 1 | Lambda | 8x A100 | 8 | 8 | 5m 14s | $3.40 | Delivered | | 2 | Hyperstack | 2x A100 PCIe | 2 | 2 | 6m 15s | $0.58 | Delivered | | 3 | RunPod | 8x A40 | 8 | 0 | No capacity | $0.60 | Not delivered, refunded | | 4 | RunPod | 4x A40 retry | 4 | 4 | 13s | $0.30 | Delivered | The first RunPod request, for eight A40 GPUs, could not be fulfilled because the supplier had no matching capacity. The platform returned the $0.60 payment automatically, as account credit, without any manual action. We then sent a follow-up request for four A40 GPUs, matched to confirmed availability, and it was fulfilled. The refund was issued as account credit, not as USDC sent back to the wallet. At the other suppliers, where the requested configuration was out of stock, the nearest in-stock multi-GPU configuration was used. That is why Hyperstack shows 2x A100 PCIe and not a larger node. So this test shows each supplier can deliver multi-GPU capacity through the payment flow. It does not show that each supplier can deliver the exact configuration you want at any moment. Every live verification run we do is published in full, with the provider, GPU count, result, time and cost for each job, including the ones that failed.
