{"name":"safe-tx-review","description":"Multisig preflight for a Gnosis Safe: this is the safe tx review, transaction review, and pre-signature check a treasury agent runs before an owner signs. Composite: one call runs safe-multisig-status + safe-tx-decode + contract-source-verified, decoding the tx first and using its target address to pull verified source. Returns current owners, threshold, nonce, and pending queue for the Safe, a decoded breakdown of the execTransaction call (target, value, operation, inner MultiSend legs), and whether the target contract's source is verified. Send safe_address plus an optional tx (an executed tx_hash, or raw calldata for a pending transaction) and chain. Read-only decode and on-chain reads only, no signing or execution. Use it as a gnosis safe check API, multisig preflight, or treasury transaction review for DAO and ops agents.","price":"$0.06","method":"POST","input_schema":{"properties":{"safe_address":{"type":"string","description":"0x-prefixed 20-byte address of the Gnosis Safe to review."},"tx":{"type":"string","description":"Optional: an executed on-chain tx_hash, or raw execTransaction calldata (0x…) for a pending transaction. safe_tx_hash is accepted as an alias."},"chain":{"type":"string","description":"Optional EVM chain slug: base, ethereum, arbitrum, optimism, or polygon.
