Give ?data=<string>&zeros=<2-6>; returns the nonce, the keccak256 hash with that many leading zero hex chars, the attempts and the time. A verifiable, self-contained anti-spam receipt a caller can check without trusting us: keccak256(data + ":" + nonce) must start with the zeros. One cent per stamp.
