2. Description (Markdown erlaubt, zum Kopieren): Compliance and pre-transaction checks for agents, priced per call. No account, no API key. **On-chain pre-flight** — will this transaction go through? Gas vs. balance, full simulation with the **revert reason decoded into plain text**, stuck nonces, contract-or-wallet recipient, ERC-20 allowance, plus a sanctions screen of the counterparty. One call, `send` / `do not send` with every blocking reason.
