Checks 1–7

N.exchange enables AI agents to guide users through supported crypto exchange flows without the agent custodying funds, holding private keys, or signing transactions on behalf of the user. N.exchange supports custodial exchange flows, non-custodial smart-contract-based DeFi flows where available, fixed-rate exchanges with a locked rate and payment window, and floating-rate exchanges where final payout may depend on execution price and slippage. Agents can use N.exchange APIs to check supported currencies, networks, pairs, rates, limits, route type, create 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.
