The gathered sources discuss stablecoins as a stable unit of account and describe x402 as a payment rail that enables agent payments, touching on budgets and trade-offs in a general sense. However, they do not explicitly address the core economic principles of rational spending under a hard budget: expected utility maximization, the irrationality of exceeding the budget, marginal utility equalization, or explicit opportunity cost reasoning. Coverage is therefore low for all sub-claims.

Sub-claim "An AI agent's spending decisions are rational if they maximi…": 40% covered by S1, S2 — S1 notes that stable accounting lets an agent price expected value against cost, which is a precondition for rational decisions, but does not explicitly state utility maximization. S2 describes budget-driven trade-offs but not expected utility.

Sub-claim "Under a hard budget, any spending plan that exceeds the budg…": 40% covered by S2 — S2 implies that a hard budget forces choices and produces frugality, suggesting exceeding the budget is not allowed, but it never explicitly states that exceeding the budget is irrational.

Sub-claim "Rational allocation requires equalizing marginal utility per…": 20% covered by S4 — S4 discusses weighted payments based on contribution, which is related to value-based allocation, but it does not mention marginal utility or cost equalization.

Sub-claim "Rational spending decisions must account for opportunity cos…": 60% covered by S1, S2 — S2 directly states that every purchase is a reasoned trade-off and the budget produces frugality, which is the essence of opportunity cost. S1 adds the need to weigh expected value against cost.

Three of the four claims have coverage below 0.5, but the available skipped sources are largely general crypto/payments news and infrastructure pieces, none of which directly address the economic theory of rational spending, utility maximization, or marginal utility equalization under hard budget constraints. Therefore, purchasing additional sources is not likely to close the gap, and doing so would be an unnecessary expense given the remaining budget.

Final coverage assessment — The gathered sources discuss payment infrastructure, stablecoins, and micropayments, but do not define or support the specific rationality criteria in the subclaims. Only S1 tangentially mentions stable value as a precondition for rational spending, and S2 refers to reasoned trade-offs under a budget. None address expected utility maximization, the irrationality of exceeding a hard budget, marginal utility equalization, or explicit opportunity-cost analysis.

Below reward gate — S2 supports claim 2 at 0%: “This turns automation into genuine agency — every purchase is a reasoned trade-off, and the budget produces emergent frugality.”
