Sub-claim "USDC enables real-time micropayments by leveraging blockchai…": 70% covered by S2, S3 — S2 confirms USDC settles onchain in seconds with final settlement. S3 shows sub-second settlement on Arc. However, S1 notes Ethereum L1 takes ~15s, which is not real-time for latency-sensitive. Coverage is good but not perfect due to potential latency on some chains.

Sub-claim "USDC's stable value and low transaction costs make it suitab…": 60% covered by S2, S4 — S2 mentions stable value and low cost implicitly. S4 discusses nanopayments with very low floor ($0.000001) and batching to reduce costs. But explicit mention of USDC's low transaction costs is limited. Coverage is moderate.

Sub-claim "USDC operates on high-throughput blockchains that minimize l…": 50% covered by S3 — S3 provides evidence of sub-second finality on Arc, a high-throughput blockchain. But no other sources discuss USDC on other high-throughput chains. Coverage is borderline.

Claim 3 has coverage 0.5, which is borderline. The Ethereum Foundation Blog and Cointelegraph may provide additional evidence on USDC operating on high-throughput blockchains. Both are affordable (0.002 each) within remaining budget. Claim 2 could also benefit from more explicit cost data, but the priority is claim 3.

Synthesizing a grounded answer from 7 source(s)…

⚖️ Sources disagreed on Settlement latency for x402 payments — S1 x402 payments take about 15 seconds to settle, similar to Ethereum L1 block time. vs S3 x402 batched settlements on Arc finalize in roughly 180 milliseconds (median 178ms). → trusted S3 (S3 provides specific, measured latency data (median 178ms, p95 240ms) from thousands of testnet calls, while S1 offers only a general estimate based on Ethereum L1 block time. S3's empirical data is more precise and internally consistent.)
