Sub-claim "The agent maximizes expected utility subject to the budget c…": 30% covered by S1, S3 — S1 mentions stablecoins as unit of account for reasoning about budgets, and S3 discusses trade-offs, but neither explicitly states maximization of expected utility.

Sub-claim "The agent never exceeds the hard budget limit.": 40% covered by S3 — S3 describes a hard budget and the need to choose within it, but does not explicitly confirm that the agent never exceeds the limit.

Sub-claim "The agent considers marginal utilities and trade-offs betwee…": 70% covered by S3 — S3 directly mentions reasoned trade-offs, choosing between sources, and stopping when enough is read, which implies marginal utility considerations.

Sub-claim "The agent updates spending decisions based on new informatio…": 50% covered by S3, S6 — S3 discusses adapting to which sources are worth paying for and when to stop, while S6 mentions weighted nanopayments adjusting based on contribution, but explicit updating is not detailed.

Coverage for claims 1 and 2 is below 0.5, but the skipped sources do not appear relevant to filling the gaps. Their previews indicate general crypto news or unrelated content, and none seem to address rational spending decisions under a hard budget. Therefore, no additional sources are recommended.

Synthesizing a grounded answer from 12 source(s)…

⚖️ Sources disagreed on Settlement time of x402 payments — S2 x402 batched settlements finalize in roughly 180 milliseconds (median 178ms, p95 240ms) on Arc testnet. vs S8 An x402 payment takes about 15 seconds to settle, similar to an Ethereum L1 block time, because each payment is its own transaction. → trusted S2 (S2 provides specific measured median and p95 latencies from testnet data, while S8 gives a rough, higher estimate. S2 is more precise and based on actual benchmarks.)
