Cryptographic witness for AI agents: paid verification and seals via x402 (USDC, Base). Two ways to pay: standard x402 (EIP-3009, PAYMENT-SIGNATURE, facilitator-settled) or transfer-then-prove (X-PAYMENT: txHash). Services: verify $0.05, audit $0.15, seal $0.05, attest $0.02; trial seal $0.01 (no free tier — every byte witnessed is paid, honest market). Loyalty: repeat payers −20%/−30% forever, automatic per wallet. Live ledger counters on the homepage. We witness. We don't judge.
