{"name":"safe-tx-decode","description":"Decodes a Gnosis Safe multisig transaction into its actual on-chain instructions: target contract, ETH value, calldata, call vs delegatecall operation, gas parameters, and signer count. Send a transaction hash and chain, or raw calldata directly, and skip manually parsing execTransaction ABI encoding by hand. Batched MultiSend calls are auto-decoded into their individual sub-transactions with each target, value, and operation broken out. Supports Ethereum, Base, Arbitrum, Optimism, Polygon, and Gnosis Chain. Use it as a Safe transaction decoder, multisig calldata decoder, or execTransaction inspector for treasury review, multisig approval audits, and forensic analysis of Safe wallet activity.","price":"$0.003","method":"POST","input_schema":{"properties":{"tx_hash":{"type":"string","description":"On-chain hash of the Safe execTransaction call to fetch and decode.
