Verification you can prove on a postcard.
Provably signs every x402 payment receipt and every AI-agent attestation it issues — so counterparties, regulators, and auditors can verify the receipt itself, not just trust the platform. The same primitives serve payment verification (x402) and AI-agent regulatory attestation, and pricing scales with how many receipts you need signed.
