The gathered sources discuss AI payment infrastructure, stablecoins as a unit of account, and unrelated AI topics, but none provide criteria for rational spending decisions under a hard budget, such as utility maximization, marginal cost-benefit analysis, temporal allocation, or enforceability of budget caps.

The gathered sources primarily discuss payment infrastructure, stablecoins, idempotency, and agent execution rails. They do not articulate a theory of rational spending under hard budget constraints. Only S5 tangentially mentions that a stable unit of account lets an agent price expected value against cost, which relates to cost-benefit reasoning, and S2 mentions user-defined limits, which relates to spending caps. However, none of the sources directly address maximizing expected total utility, marginal analysis, temporal budget allocation, or feasibility/enforceability of planned expenditures under a hard budget.

Sub-claim "A rational AI agent's spending decisions under a hard budget…": 40% covered by S5, S2, S7 — S5 explicitly notes that a stable unit of account lets an agent price expected value against cost, a precondition for rational constrained spending. S2 shows agents acting within user-defined limits, and S7 shows autonomous runtime purchasing, but none explicitly describes expected utility maximization under a hard budget.
Sub-claim "Rationality requires evaluating each potential expenditure b…": 30% covered by S5, S7 — S5 supports pricing expected value against cost, and S7 supports agents discovering/purchasing data, but neither explicitly addresses marginal benefit, trade-offs, or alternative uses of remaining funds.
Sub-claim "Rational decisions account for the budget's temporal scope, …": 10% covered — No gathered source discusses temporal budget allocation, intertemporal trade-offs, or avoiding premature fund exhaustion. S4 only reports aggregate spending trends over time, not agent budget planning.
Sub-claim "Under a hard budget, rational spending must respect the infe…": 70% covered by S2, S10, S5 — S2 directly describes AI agents executing trades within user-defined limits, S10 covers idempotency keys preventing double-spends (enforceability), and S5 emphasizes stable budgets for meaningful constraints. Together these provide solid support for feasibility and enforceability of a hard cap.
The only significant coverage gap is temporal budget allocation, but the available skipped sources do not substantively address that topic. Conzit Labs is about building a cost-effective bot without vendor lock-in, TutorMoments is about pedagogical timing, and the rest are unrelated (DeFi, gardening, retro hardware, esoteric cosmology). Buying them would not meaningfully raise claim 3 coverage, so no purchases are recommended.

Final coverage assessment — The gathered sources focus on payment infrastructure for AI agents (x402, stablecoins, idempotency, settlement latency) but none directly address the normative principles of rational spending decisions under a hard budget. The closest match is S5, which mentions that stable accounting is a precondition for rational spending, and S2/S10, which relate to enforcing limits, but the core economic concepts of utility maximization, marginal benefit, temporal allocation, and comprehensive budget enforceability are not covered.

⚖️ Sources disagreed on Settlement time for x402 payments — S11 Arc testnet settlements finalize in roughly 180 milliseconds. vs S12 x402 payments take about 15 seconds to settle, similar to an Ethereum L1 block time. → trusted S11 (S11 provides specific benchmark data (median 178ms, p95 240ms) from testnet deployments, while S12 offers a general estimate based on block times. The measured latency from S11 is more specific and recent for the context of agent payments.)

A rational AI agent's spending decisions under a hard budget are characterized by maximizing expected total utility within the budget constraint . Rationality requires evaluating each potential expenditure by its marginal expected benefit relative to its cost and to alternative uses of remaining funds . Rational decisions must also account for the budget's temporal scope, allocating resources across time to avoid exhausting funds before high-value opportunities arise . Furthermore, under a hard budget, rational spending must respect the infeasibility of exceeding the cap, meaning all planned expenditures must be feasible and enforceable .
