Checks 1–7

N.exchange DeFi Agent enables AI agents to guide users through non-custodial, smart-contract-based crypto exchange flows. This identity creates non-custodial DeFi orders only: the agent never custodies funds, holds private keys, or signs transactions on behalf of the user, and no order created under this identity is custodial. It supports floating-rate exchanges, where the final payout depends on execution price and network costs, and fixed-rate exchanges, where a quoted rate is held for a short payment window. Agents can use N.exchange APIs to check supported currencies, networks, pairs, rates and limits, create non-custodial orders, present payment instructions, and monitor order status. Agents must always apply the current N.exchange Terms, route availability, compliance controls, and product-specific rules before offering, quoting, or creating an order.

Everything above is one sweep, pinned to one block. This asks the same checker to run the same ladder against this agent right now — one request to its declared document, at the current head. The answer belongs to no run, is stored nowhere, and never enters a published rate or finding.
