Top reputation on subject (50/100), directly about AI agent payment rails (x402), and cached—reusing at no cost is optimal. Highest historical citation rate (63%) and weight. — selected for the claim-aware evidence portfolio (targets claims 1, 2, 3, 4; 0 fetch USDC, 1 attention slot).
Good reputation (33/100), topic on ontologies for AI agents—could inform structured decision-making under constraints. Cached, reusable. — selected for the claim-aware evidence portfolio (targets claims 2, 3; 0 fetch USDC, 1 attention slot).
Strong reputation (29/100), covers stablecoins as unit of account—relevant to budget rationality under stable pricing. Cached and reusable. — selected for the claim-aware evidence portfolio (targets claims 1, 2; 0 fetch USDC, 1 attention slot).

External:true (Simon Willison's Weblog). Real topical value: discusses AI model cost vs. user adoption, relevant to budget constraints. However, it's an off-rail live endpoint—cannot settle this run. Not cached.
External:true (Vitalik Buterin's website). Minimal direct relevance to AI agent spending rationality under a hard budget; more about DeFi yield. Off-rail chain, not cached.
External:true (The Coinbase Blog). About sanctions and Tornado Cash—not directly about budget rationality or AI agent spending. Off-rail chain, not cached.
External:true (Decrypt). Topic is AI kill switch—regulatory, not about spending rationality under a budget. Off-rail chain, not cached.
External:true (Inner Axiom). Completely off-topic (esoteric mysticism). Not cached, not relevant.
External:true (Conzit Labs). About AI capital expenditure—tangential, but not about agent spending decisions under a budget. Off-rail chain, not cached.
External:true (Hugging Face - Blog). About ML training/deployment—tangential to agent infrastructure, not spending rationality. Off-rail chain, not cached.
Cached, and idempotency keys are relevant to preventing double-spends in agent transactions—important for budget safety. Low cost, moderate value. — cached bytes are free, but this read does not clear the attention gate (EV 0.40, minimum 0.45, with a required claim target).
CoinDesk with decent reputation (18/100). Article on AI-powered crypto trading app—tangentially relevant to agent spending interfaces. Cached. — the claim-aware portfolio chose a stronger, less redundant set inside the 4-source attention and $0.025000 fetch-budget caps, so this proposal stays unspent.
Stripe Blog, though low reputation (2/100), has cached article on AI spending patterns—could provide data on budget allocation. Reuse for free. — cached bytes are free, but this read does not clear the attention gate (EV 0.40, minimum 0.45, with a required claim target).
Ethereum Foundation Blog, reputation 0/100, but cached article on AI agents in protocol code—tangential to agent execution, not spending. Reuse cautiously. — cached bytes are free, but this read does not clear the attention gate (EV 0.30, minimum 0.45, with a required claim target).
Cointelegraph news, reputation 22/100, but article is about Bitcoin price drop—macro, not about agent spending rationality. Not cached, not worth buying.
Onchain Micropayments Digest, reputation 10/100, but cached and about nanopayments—relevant to fine-grained budget allocation. Reuse. — the claim-aware portfolio chose a stronger, less redundant set inside the 4-source attention and $0.025000 fetch-budget caps, so this proposal stays unspent.
Arc Settlement Benchmarks, reputation 12/100, cached and about settlement latency—relevant to timing and opportunity costs. Reuse. — cached bytes are free, but this read does not clear the attention gate (EV 0.40, minimum 0.45, with a required claim target).

Final coverage assessment — The gathered sources discuss stablecoins as a stable unit of account and x402 payment rails, but they do not explain or justify budget-constrained utility maximization, marginal allocation, opportunity costs, or dynamic reallocation as the gathered budget shrinks. Only S3 vaguely gestures at pricing expected value against cost as a precondition for rational spending, so there is insufficient evidence to answer the question fully.

Done. Spent $0.025 across 1 confirmed/simulated payment(s) to creators.

The provided sources do not directly support any of the four subclaims about rational spending under a hard budget. No source discusses maximizing expected total utility subject to a hard constraint, marginal expected utility per unit cost, opportunity costs, or dynamic reallocation as the budget shrinks. The only related statement is that a stable unit of account is a precondition for rational spending decisions .
Evidence ledger — quotes verified before rewards
Rational spending under a hard budget requires maximizing expected total utility subject to the constraint that total costs do not exceed the budget.
20%“Dollar stablecoins like USDC let an agent price expected value against cost in stable terms, which is a precondition for rational spending decisions.” [S3] Stablecoins as the unit of account for agents
A rational agent allocates each unit of budget to the option with the highest marginal expected utility per unit cost, rather than simply pursuing the highest absolute utility.
0%No reward-qualifying evidence
Under a hard budget, rational decisions must account for opportunity costs, since choosing one expenditure necessarily forgoes alternative uses of the same limited funds.
0%No reward-qualifying evidence
Rationality under a hard budget also involves dynamically adjusting spending priorities when remaining budget shrinks, ensuring that at every decision point the expected marginal benefit of remaining expenditures is maximized.
