Decodes raw EVM transactions and calldata into agent-readable intent

Decodes raw EVM transactions and calldata into agent-readable intent: function signature, decoded arguments, and ERC-20 transfers. POST /v1/evm with {tx_hash, chain_id} and get one JSON object back. Fully deterministic: input determines output. Pay per request in USDC; no account, no API key.

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.
