    Card live

    Mint a generative punk from punks.generated.eth on Ethereum for 0.002 ETH each (up to 10 per tx, no supply cap). Art is fully on chain and every punk gets its own N.punks.generated.eth name. Use the MCP tools (mint returns an unsigned mint(qty) tx you sign; it mints to the sender) or the x402 direct-mint endpoint (custom scheme, paid in native ETH; non-custodial, the server never holds keys or funds). Or pay USDC on Base via standard x402 exact at https://punks-generated-eth.enspiration-eth.workers.dev/x402/base/mint (custodial: the service mints on mainnet and delivers to you, poll statusUrl, refund on failure, 5% service fee). Trade peer to peer on Seaport. Punk holders can turn their punk into their own ERC-8004 agent identity at https://punks-generated-eth.enspiration-eth.workers.dev/erc8004/punk/{id}.
