Sub-claim "Stablecoins are used as a standard measure of value, indicat…": 90% covered by S1 — S1 explicitly states that autonomous agents need a stable unit of account and that dollar stablecoins like USDC allow an agent to price expected value against cost in stable terms, directly supporting stablecoins as a standard measure of value.

Sub-claim "The designation of stablecoins as a unit of account for agen…": 65% covered by S1 — S1 contrasts stablecoins with volatile tokens, noting that a volatile token makes stable pricing meaningless, which implies an expectation of stable purchasing power. However, the text does not explicitly discuss trust or purchasing power over an extended time horizon.

Sub-claim "Agents, such as automated systems or institutional actors, r…": 70% covered by S1, S2 — S1 directly shows agents using stablecoins to denominate budgets and expected value in stable terms. S2 supports the broader financial-infrastructure angle by describing agent payment rails, though it does not explicitly name stablecoins. Together they provide decent coverage of the claim.

Sub-claim "This phrase reveals that stablecoins are evolving beyond a m…": 55% covered by S1, S2, S3 — S1 positions stablecoins as a precondition for rational agent spending, which is more than a simple medium-of-exchange role. S2 and S3 describe payment/settlement infrastructure supporting agent economies. The claim is partially supported, but the source texts do not explicitly articulate the 'foundational accounting layer' framing.

All sub-claims have coverage at or above 0.55, so no single claim falls below the 0.5 threshold that would trigger a recommendation to purchase additional sources. The gathered content adequately supports the core ideas, and remaining budget does not need to be spent.

Final coverage assessment — The gathered sources provide sufficient information to address all sub-claims. S1 directly explains why stablecoins are used as a unit of account by autonomous agents, citing the need for a stable value for rational spending decisions. This covers the core concepts of stablecoins as a measure of value, maintaining stable purchasing power, and their integration into financial infrastructure for agents. S2 and S3 provide context about agent payment systems (x402) and settlement, which supports the idea of stablecoins being part of the financial infrastructure for agents, though not explicitly about their role as a unit of account. Overall, the sources cover the sub-claims well enough to answer the question confidently.
