Request → AI Agent or user accesses a resource (e.g., Harmonybot endpoint). Response → Server replies with HTTP 402 + payment metadata: Pay 0.00037 eth ETH / 1.5605 USDC to mint one Warplet NFT. Settlement → x402 verifies payment instantly (~200 ms). Mint → Smart contract on Base deploys and mints the unique Warplet NFT (metadata derived from Harmonybot generative output). Ownership → NFT is stored on-chain, representing a snapshot of that Harmonybot art at the moment of mint.
