Temporary 50-cent paid pre-action check. This existing MCP tool retains the legacy _1usd name for compatibility; verify the live catalog price and terms rather than interpreting the tool name as the price. Before an autonomous agent spends money, shares non-public data, delegates authority, or creates external side effects, create an unpaid GovOmniAI Agent Action Assurance Check order. It returns an assurance tier, evidence sufficiency, missing/weak evidence, risk factors, and whether a human gate is warranted. The result is sealed before payment. This tool does not charge the buyer; it returns the MPP payment endpoint, order token, terms, and status URL so the independently authorized buyer agent decides whether to pay.
