exhibit402-mcp
Pay with x402 (USDC on Base) to certify what a URL serves right now, and to re-verify existing certificates. certify_url ($1.00 fullpage / $0.50 viewport): two independent observers capture the URL at one frozen timestamp. Matching captures are tier CERTIFIED, differing ones are WITNESSED with a pixel-agreement percent and diff map. Evidence is stored permanently on Arweave and an ERC-721 certificate is minted on Base to the paying wallet. verify_certificate ($0.02): re-verifies any exhibit402 certificate by token id, Arweave manifest tx id, or job id, recomputing hashes from the act
