Sub-claim "What does the concept of "Stablecoins as the unit of account…": 70% covered by S1 — S1 explicitly states that dollar stablecoins like USDC let an agent price expected value against cost in stable terms, revealing USDC's function as a stable unit of account enabling rational spending decisions. It directly answers the core characteristic/function, though it does not elaborate on USDC-specific mechanics beyond the stable-dollar property.

Sub-claim "How is USDC utilized as a unit of account by agents in vario…": 40% covered by S1 — S1 describes the general use (agents pricing expected value against cost in stable terms, a precondition for rational spending) but does not cover 'various applications' or concrete practical deployments. S2 mentions Coinbase enabling USDC payments from AI agents but is only an abstract about trading tools and a developer kit, not unit-of-account usage. Partial answer only.

Sub-claim "What implications does USDC's use as a unit of account for a…": 20% covered by S1 — S1 implies stability is the reason USDC works as a unit of account (contrasting volatile tokens), giving topical context on stability, but it does not address adoption implications or comparisons to other currencies. No source covers adoption or currency comparison.

Coverage is adequate for the core question (claim 1 at 0.7). The remaining gaps concern applications, adoption, and currency comparison, but none of the affordable skipped sources (all ≤0.005, within the 0.02 budget) address USDC as a unit of account for agents—they cover x402 rails, nanopayments, idempotency, Ethereum agent triage, ontologies, and unrelated topics. Buying them would not fill the gaps, so no purchase is recommended.

Final check — "What does the concept of "Stablecoins as the unit of account…": 90% assessed by S1

Final check — "How is USDC utilized as a unit of account by agents in vario…": 50% assessed by S1

Final check — "What implications does USDC's use as a unit of account for a…": 40% assessed by S1

Final coverage assessment — S1 directly answers the core question: it states that dollar stablecoins like USDC provide a stable unit of account that lets agents price expected value against cost in stable terms, a precondition for rational spending decisions. This covers USDC's characteristic/function as a stable unit of account and its practicality for agent budgeting. However, the sub-claims also ask about utilization across various applications and implications for stability, adoption, or comparison to other currencies. S1 gives only a general rationale, not concrete applications or comparative/adoption implications. S2 and S3 mention agent payments and wallets but do not address USDC as a unit of account, so they provide no coverage for these sub-claims. The assessment does not establish a complete supported answer for every requested part.
