Sub-claim "Rational spending decisions maximize expected utility subjec…": 0% covered — No gathered source discusses expected utility maximization or the optimization criterion under a hard budget. S1 only notes stablecoins are a precondition for rational budget reasoning, not the maximization rule.
Sub-claim "Rational spending decisions never exceed the hard budget lim…": 0% covered — None of the sources address enforcing or respecting a hard budget ceiling. S3 covers idempotency to prevent double-charging, but not budget-limit compliance.
Sub-claim "Rational spending decisions account for opportunity costs by…": 0% covered — No source mentions opportunity cost, marginal benefit, or comparison across alternative expenditures. The gathered material is about payment rails, settle latency, and stablecoins.
Sub-claim "Rational spending decisions allocate resources to the highes…": 0% covered — No source describes prioritizing or ranking expenditures by value within a budget. S5 describes agents paying per request but not allocating a scarce budget to highest-value uses.
All sub-claims are essentially uncovered. The skipped sources are priced within budget but none appear to address the economics of rational agent spending under a hard budget (e.g., expected utility, opportunity cost, budget enforcement, or value-based allocation). One possible near-miss, TutorMoments, concerns AI tutor intervention timing, not budget-constrained spending, so buying it would not materially improve coverage.

Final coverage assessment — The gathered sources provide background on payment infrastructure (idempotency, settlement latency, micropayments) and mention user-defined limits, but none define or explain rationality under a hard budget. S1 notes a stable unit of account is a precondition for rational spending, S4 mentions user-defined limits, and S3 prevents double-charging, but no source addresses maximizing expected utility, never exceeding a hard budget as a rational principle, opportunity costs, or highest-value allocation.
Synthesizing a grounded answer from 9 source(s)…
⚖️ Sources disagreed on x402 settlement latency — S6 About 15 seconds to settle, similar to an Ethereum L1 block time, because each payment is its own transaction waiting to be mined. vs S7 Batched settlements finalize in roughly 180 milliseconds (median 178ms, p95 240ms) on Arc testnet. → trusted S7 (S7 reports measured benchmark data across thousands of calls with median and percentile values, whereas S6 explicitly states 'our reading' and relies on an analogy to Ethereum L1 block times.)

Under a hard budget, an AI agent's spending decisions are rational when the agent can price expected value against cost in a stable unit of account, enforce explicit limits without double-charging, and keep transaction overhead low enough to make small payments viable.
- Stable unit of account: A volatile token makes a hard budget like “spend at most $0.05” meaningless. Dollar stablecoins “let an agent price expected value against cost in stable terms, which is a precondition for rational spending decisions.” - Hard budget enforcement: User-defined limits—as in the Agent Wallet that “lets AI agents execute on-chain trades within user-defined limits”—define the budget ceiling. Idempotency keys also prevent a retried request from being “charging twice,” so the agent cannot accidentally exceed its budget via duplicate payments. - Low transaction overhead: Nanopayments lower the “minimum economical payment” and make paying a fraction of a cent per citation viable, enabling cost-effective micro-spending within a budget.
The sources do not, however, describe a full opportunity-cost ranking or an explicit algorithm for allocating to the highest-value use. They provide preconditions—stable accounting, enforcement, and low overhead—that make such rational spending decisions possible.
