Web Payments Review on x402 timing has 7% citation rate but decent reward when cited. Directly about settlement timing which relates to cost-quality decisions in payment systems. At $0.002, it's cheap enough to include.
High average weight and reward when cited, but lower citation rate (17%). The idempotency key concept is relevant to agent decision reliability and could inform risk thresholds. Worth the $0.003 toll.
Highest reputation source on this subject (36/100, 55% citation rate). The article title 'Budgets make agents decide' is a direct match to the question's core logic. High expected value justifies the $0.004 price.
Strong historical citation rate (40%) and decent reward on this subject. Directly relevant to agent budgeting and cost-quality tradeoffs via stablecoin unit-of-account framing. Worth the $0.003 toll.
Moderate citation rate (20%) but lower reward. The topic of nanopayment floors is tangentially relevant to cost-threshold decisions, but not a core fit. Acceptable as a supporting source at $0.005 given the budget.
Arc settlement benchmarks have some relevance to understanding cost-speed tradeoffs in payments. Low citation rate (10%) but provides concrete data on latency vs. cost. Worth the $0.003 as a supporting source.
Gardening content is completely off-topic for agent economics and source selection. No relevance to the question.

Hugging Face voice AI post is irrelevant to agent budgeting and source quality decisions.
Vitalik's DeFi post has 0% citation history on this subject. While about Ethereum economics, not specific to agent source cost-benefit analysis.

The gathered sources discuss x402 payment settlement timing and idempotency keys for preventing double-spends, neither of which addresses how an agent should decide when a cheaper source is good enough. The sources provide no information on quality-cost trade-offs, risk thresholds, or marginal value comparisons. Therefore, they do not support any of the sub-claims.

The gathered sources only mention that an agent under a budget must decide when a cheaper source suffices, but they do not provide criteria for judging quality reduction, setting risk thresholds, or comparing marginal value against cost. Most subclaims are unsupported in detail.

The retrieved sources discuss agent budgets and the need for a stable unit of account, but they do not specify a concrete decision criterion for when a cheaper source is good enough. S3 mentions deciding when cheaper sources suffice, and S4 mentions pricing expected value against cost, but neither source provides the required threshold or comparison rule for quality degradation, acceptable risk, or marginal value.

The sources provide general principles about budgets and cost-value trade-offs, but they do not fully specify the decision criteria for when a cheaper source is good enough. Specifically, the idea of risk/error thresholds based on consequences is only weakly implied (S3), and the marginal analysis is not explicitly detailed (S4, S3).

The gathered sources discuss agent budgeting, stable units of account, and micropayment mechanics, but they do not provide a concrete decision rule for when a cheaper source is good enough. Sub-claim 2 is especially weak: no source addresses setting an explicit threshold based on consequences of inferior-source errors. Sub-claims 1 and 3 have only partial support from general statements about weighing value against cost and choosing what to pay for.

Final check — "The agent should compare the marginal value of the more expe…": 10% assessed by S3, S4
Final coverage assessment — None of the gathered sources describe a decision procedure or criteria for when a cheaper source is good enough. S3 mentions that an agent must decide when a cheaper source suffices, and S4 notes that agents need a stable unit of account to price value against cost, but neither source specifies how to compare quality reductions, set risk thresholds, or evaluate marginal value versus cost. The sub-claims are therefore not adequately covered.

An agent should decide when a cheaper source is good enough by evaluating trade-offs between cost, quality, and risk. When operating under a hard budget, the agent must choose which sources are worth paying for, when a cheaper source suffices, and when it has read enough to stop . This requires a stable unit of account to reason about budgets and price expected value against cost in stable terms, which is a precondition for rational spending decisions . The decision involves comparing the marginal value of a more expensive source against its additional cost to determine if the cheaper source meets the task's requirements .
Evidence ledger — quotes verified before rewards
The agent should accept a cheaper source when the expected reduction in quality does not exceed the cost savings, given the task's requirements.
10%“An agent under a hard budget must choose: which sources are worth paying for, when a cheaper source suffices, and when it has read enough to stop.” [S3] Budgets make agents decide, not just automate
The agent should determine a threshold for acceptable risk or error based on the consequences of using an inferior source.
0%No reward-qualifying evidence
The agent should compare the marginal value of the more expensive source against its additional cost to decide if the cheaper source is sufficient.
