Second-highest reputation (30/100) with solid citation history. Stablecoins as unit of account is foundational for budgeting and cost evaluation. Cached, so free. — selected for the claim-aware evidence portfolio (targets claims 1, 2; 0 fetch USDC, 1 attention slot).
Stripe data on AI spending patterns provides empirical grounding for rational expenditure decisions. Cached, so free despite low historical reputation (4/100). — 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.
MetaMask agent wallet with user-defined limits is a practical example of budget-constrained spending. Cached, free. Moderate relevance to sub-claims about hard budget limits. — cached bytes are free, but this read does not clear the attention gate (EV 0.40, minimum 0.45, with a required claim target).
Idempotency keys prevent double-spends, which is a technical detail about reliable spending, but not core to the decision-making framework under budget constraints. Low marginal value for this question.
Good reputation (25/100) with empirical citation data. AI-to-crypto rotation discusses capital allocation decisions, relevant to rational spending. Not cached, so must buy, but cheap at $0.002. — 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.
Robinhood's AI-powered crypto app is tangential; shows AI tools in trading but not core to agent budget decision theory. Cached, free but low relevance. — the free-preview coverage check could not connect this source to any sub-claim, so no toll is authorized.
Coinbase reconciliation is a backend systems problem, not about agent decision-making under budget constraints. Not in historical data for this topic; low expected value.
Arc settlement benchmarks are about technical performance, not decision theory. Low historical reputation (11/100) for this topic. Cached, free but minimal relevance. — the free-preview coverage check could not connect this source to any sub-claim, so no toll is authorized.
x402 payment timing is a technical detail, not central to rational spending decisions. Low historical reputation (6/100). Cached, free but not high-value. — the free-preview coverage check could not connect this source to any sub-claim, so no toll is authorized.
Esoteric mythological content is completely irrelevant to AI agent budget decisions. No tags matching the topic. Skip regardless of price.
AI capital expenditure is about infrastructure spending, not agent-level decision-making under budget constraints. Conzit Labs has zero historical citations on this topic. Not cached, skip.
Retro console repair is completely off-topic. No relation to AI agents or spending decisions. Skip.
Gradio workflow guide is about ML deployment tools, not agent economics or budget decisions. Not cached, no historical data, low topical fit.
Vitalik's post on low-risk DeFi discusses rational resource allocation in Ethereum context, tangentially relevant to agent spending. New source, not cached, worth a small bet at $0.004. — 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.

Sub-claim "Rational spending decisions maximize expected utility subjec…": 30% covered by S4 — S4 notes that stable tokens let an agent 'price expected value against cost in stable terms' as a precondition for rational spending, but it does not explicitly state utility maximization under a hard budget constraint.
Sub-claim "The agent considers all relevant costs and benefits of each …": 40% covered by S4 — S4 directly refers to pricing expected value against cost, which implies comparing benefits and costs, though it does not enumerate all relevant factors.

Sub-claim "The agent never exceeds the hard budget limit.": 0% covered — No gathered content discusses hard budget limits or enforcement mechanisms.
Coverage is low for most claims, but none of the affordable skipped sources substantively address the theoretical requirements of rational budget decisions (utility maximization, marginal utility, absolute budget adherence). The available previews focus on payment rails, crypto trading, x402 latency, and unrelated topics, so buying them would not adequately fill the gaps.

Final coverage assessment — None of the gathered sources directly address normative principles of rational spending under a hard budget. S4 mentions stablecoins as a precondition for reasoning about budgets and comparing expected value to cost, but it does not define rational spending, utility maximization, marginal utility equalization, or explicit enforcement of budget limits. The other sources discuss payment rails and ontologies, not budget rationality.

Rational spending decisions under a hard budget are supported in the sources mainly through the use of a stable unit of account. A volatile token makes a budget limit like “spend at most $0.05” meaningless, whereas dollar stablecoins like USDC let an agent price expected value against cost in stable terms, which is a precondition for rational spending decisions . This implies the agent must weigh expected benefits against costs for each expenditure (subclaim 1). The sources do not explicitly support utility maximization subject to the budget (subclaim 0), equalizing marginal utility per unit of cost (subclaim 2), or a categorical rule that the agent never exceeds the hard budget (subclaim 3).
