CoinDesk article on AI supercharging crypto aligns with agent spending rationality. Highest citation rate (53%) and strong historical performance.
Binance opening crypto trading to AI agents with user-set controls directly relates to agent spending decisions and budget constraints (subClaim 3). Not cached, price $0.002 is low.
Stripe's analysis of AI spending patterns could inform rational budgeting, though lower historical citation rate (10%). Cached and cheap.
Stablecoins as unit of account directly supports rational budgeting under a hard budget (subClaim 1). High citation rate (45%) and avg reward justify reuse.
x402 payment rail is central to agent spending decisions and budget constraints. Strong historical citation rate (32%) and high avg weight (0.79) signal value. — the 4-source attention budget is full, so lower-ranked evidence is skipped.
x402 payment timing is relevant to budget planning and opportunity costs (subClaim 2). Low historical citation rate (25%) but cached. — cached bytes are free, but this read does not clear the attention gate (EV 0.40, minimum 0.45, with a required claim target).
Arc settlement benchmarks provide technical details on payment finality, which relates to budget timing decisions. Low citation rate (10%) but cached and specific. — the 4-source attention budget is full, so lower-ranked evidence is skipped.
Ethereum Foundation's use of AI agents for code triage is tangential to rational spending decisions under budget constraints. Low citation rate (13%).
Ontologies for AI agents could relate to rational decision-making frameworks, but less direct. High avg weight when cited (1.0) but low citation rate (18%). — cached bytes are free, but this read does not clear the attention gate (EV 0.60, minimum 0.45, with a required claim target).
Nanopayments are relevant to low-cost spending but less directly tied to rational decision-making under budget constraints. No historical citation data; price $0.005 is relatively high.
Runaway AI agent story is about safety, not rational spending under budget. Not cached, price $0.003.
Vitalik's piece on low-risk DeFi is about Ethereum strategy, not agent budget rationality. Not cached, price $0.004.
Idempotency keys are a technical detail for double-spend prevention, not core to rational budgeting logic. Zero citations on this subject despite being read.
Memory requirements for agents is a technical detail, not directly about rational spending decisions. Not cached, price $0.003.
Coinbase's reconciliation article is a technical implementation detail, not about agent decision-making. Cached but irrelevant.
Russia's crypto law is regulatory news, not directly relevant to rational agent spending under budget constraints. Low historical citation rate (26%).

Final coverage assessment — None of the gathered sources define or characterize rational spending under a hard budget. They cover AI agents' crypto trading, user controls, aggregate spending trends, and stablecoins as a stable unit of account, but do not mention utility maximization, marginal utility per cost, opportunity costs, or dynamic stop conditions. S4 is tangentially related to pricing expected value against cost, but it does not address the specific subclaims.

An AI agent's spending decisions are rational under a hard budget when they are grounded in a stable unit of account, allowing the agent to reason about costs and expected value in consistent terms. This is a precondition for making meaningful spending choices.
Without such stability, a budget constraint becomes effectively meaningless. Dollar stablecoins like USDC provide this necessary stability, enabling an agent to price expected value against cost and make rational decisions.
Evidence ledger — quotes verified before rewards
Rational spending under a hard budget maximizes total expected utility without exceeding the budget constraint.

It prioritizes expenditures by marginal utility per unit cost, selecting the highest-value options first.
0%No reward-qualifying evidence
It accounts for opportunity costs and the value of preserving budget for future high-value uses.
0%No reward-qualifying evidence
It dynamically adjusts spending over time and stops before budget exhaustion when no remaining expenditure has positive expected net value.
