Sub-claim "What is the main point regarding USDC as a unit of account f…": 70% covered by S2 — S2 directly states that USDC is the de facto standard for AI agent settlements, with $18.3 trillion in transaction volume representing ~55% of stablecoin activity, and that stablecoins like USDC provide price stability suitable for business transactions where predictable costs matter. It also notes USDC settlement via x402 and that stablecoin payments for AI agents involve USDC for services, APIs, or agent-to-agent commerce. However, the main point is not explicitly framed as 'unit of account'—the passages emphasize settlement and payment medium rather than accounting denomination. S1 provides general USDC issuance/redemption but no agent commerce context.
Sub-claim "What does Stablecoin Ledger say about USDC as a unit of acco…": 0% covered — No gathered source is named 'Stablecoin Ledger' or contains passages from such a source. S1 is circle.com and S2 is nevermined.ai. The skipped sources include items about Ledger Wallet (hardware wallet) and stablecoin management, but none are identified as 'Stablecoin Ledger' and none provide statements about USDC as a unit of account for agent commerce. Therefore, this specific sub-claim is entirely uncovered.
The first sub-claim is partially covered (0.7) by S2, but the second sub-claim about 'Stablecoin Ledger' has zero coverage. The skipped source 'USDC Founder Aims to Weld Stablecoins and Agentic Commerce' (price 0) likely discusses agent commerce and may mention Stablecoin Ledger or related views. The skipped source 'Stablecoins in Agentic Commerce - insights4vc' (price 0) explicitly discusses USDC as programmable medium of exchange in agentic commerce and may contain the Stablecoin Ledger perspective. Both are free and could fill the gap. No paid sources are needed given remaining budget and availability of free candidates.
Public gap read unavailable (transport-unavailable); claim remains unknown.

Final check — "What is the main point regarding USDC as a unit of account f…": 80% assessed by S2, S3
Final check — "What does Stablecoin Ledger say about USDC as a unit of acco…": 0% assessed
Final coverage assessment — The question asks for the main point about USDC as a unit of account for agent commerce and what Stablecoin Ledger says about it. The gathered sources include Circle's USDC page (S1), Nevermined statistics (S2), and a Substack article (S3). None of the sources mention 'Stablecoin Ledger' by name. S2 and S3 discuss USDC in agent commerce, but they do not provide a specific statement from Stablecoin Ledger. The main point is partially supported: S2 states USDC is the de facto standard for AI agent settlements, and S3 discusses stablecoin settlement in agentic commerce. However, the second sub-claim about Stablecoin Ledger is entirely unsupported. The assessment does not establish a complete supported answer for every requested part.
