x402 payments are live: real GPU compute, paid for by AI agents
by DamianThis week we got x402 fully working end to end on Kilawatt Cloud, not a testnet demo.
An AI agent hits our API, gets a 402 Payment Required challenge, pays instantly in USDC on Base, and gets a running GPU instance in the same request. No card, no signup, no human involved.
Ran two real settlements today. Both confirmed on-chain, both showed up as real Stripe payouts on our end.
Most x402 integrations so far are lightweight stuff, API metering, content paywalls. Getting something capital-intensive like GPU provisioning working through the same flow was a bigger lift, but it's live now.
Happy to talk through the implementation if anyone's building something similar.
