ERC-8004 reputation loaded — composite scores on this subject.
Cached & relevant: Stripe data on AI spending patterns provides empirical evidence for rational budget allocation; high historical citation performance (6/42 runs, reputation 11/100).
Cached & somewhat relevant: Ethereum Foundation's AI agent work touches on rational protocol interactions; moderate historical citation performance (2/27 runs, reputation 6/100).
Cached & highly relevant: stablecoins as the unit of account directly addresses rational budgeting under hard constraints, with strong historical citation performance (21/46 runs, reputation 26/100).
Cached & somewhat relevant: MetaMask AI wallet with spending limits directly relates to budget constraints; moderate historical citation performance (9/32 runs, reputation 9/100).
Cached & relevant: x402 payment timing is about settlement trade-offs; low historical citation performance (2/33 runs, reputation 1/100). — cached bytes are free, but this read does not clear the attention gate (EV 0.40, minimum 0.45, with a required claim target).
Cached & valuable: x402 payment rail mechanics are core to how agents spend, aligning with rational allocation under constraints; good citation history (10/44 runs, reputation 13/100). — the 4-source attention budget is full, so lower-ranked evidence is skipped.
Cached & relevant: x402 settlement latency benchmarks inform trade-offs in rational payment decisions; moderate historical citation performance (4/36 runs, reputation 4/100). — the 4-source attention budget is full, so lower-ranked evidence is skipped.
Cached & relevant: ontologies for agent boundaries directly relates to rational decision-making under constraints; moderate historical citation performance (1/21 runs, reputation 5/100). — the 4-source attention budget is full, so lower-ranked evidence is skipped.
Cached but tangential: idempotency keys are about system reliability, not budget constraints; low historical citation performance (6/31 runs, reputation 4/100). — cached bytes are free, but this read does not clear the attention gate (EV 0.40, minimum 0.45, with a required claim target).
Cached but lower relevance: nanopayments and batching are technical details, not directly about rational decision-making; weak historical citation performance (2/28 runs, reputation 2/100). — the 4-source attention budget is full, so lower-ranked evidence is skipped.
Not cached: crypto rotation news is market-focused, not directly about rational budgeting; moderate historical citation performance (5/21 runs, reputation 6/100), but not worth the price given budget constraints.
Not cached: token spending news is about cost control, but not specifically about rational budget constraints; no historical citation data on this subject.
Not cached: Wintermute's regulatory approval is about market structure, not agent spending rationality; moderate historical citation performance (3/9 runs, reputation 21/100), but not worth the price.
Not cached: DeFi discussion is about Ethereum economics, not directly about agent budget rationality; no historical citation data on this subject.
Not cached: agent security risks are about account management, not spending rationality; no historical citation data on this subject.
Not cached: voice agent building is technical implementation, not about rational spending decisions; no historical citation data on this subject.
Cached but outdated: 2022 Coinbase fee updates are irrelevant to current agent spending decisions; no historical citation data on this subject.

Final coverage assessment — The gathered sources discuss AI agent spending trends, stablecoin accounting, and agent wallet limits, but none directly define what makes spending decisions rational under a hard budget. They offer only tangential or indirect relevance, so the claims cannot be substantiated.

Rational spending decisions under a hard budget require maximizing expected utility within the constraint, allocating resources to options with the highest marginal utility per unit of cost, avoiding budget overruns while prioritizing high-impact expenditures, and accounting for opportunity costs. This is supported by the need for stable unit of account to enable rational pricing and decision-making .
