MioDio Meridian parameter-drift check
MioDio Meridian parameter-drift check: diffs a declared intent against the exact unsigned tx or EIP-712 payload before you sign (~$0.005 USDC Exact on Base). Verdict match, drift or cannot_verify with a per-field diff and keccak of the bytes checked. Unknown calldata is cannot_verify, never match. A match is not a guarantee the intent was safe. Errors: 400 invalid_body or unsupported_chain, 402 payment required. MioDio x402 DeFi. Terms: https://workers.miodiollc.com/terms
Paid test badge: not yet. The checks above are free: we call the tool without paying and read the payment request it sends back. The Verified badge needs paid calls whose answers match the promised output, and nobody can buy a badge.
