Sub-claim "Circle's Gateway facilitates settling sub-cent USDC payments…": 60% covered by S4 — S4 mentions 'Gateway-batched payment' settling in sub-second time on Arc, which implies a gateway mechanism. However, it does not explicitly state that this gateway is Circle's or that it is specifically for sub-cent payments.
Sub-claim "It processes payments smaller than one cent in USDC.": 50% covered by S7 — S7 discusses 'weighted nanopayments' and 'granular settlement' in USDC, which aligns with sub-cent transactions. But it does not explicitly mention payments under 0.01 USDC or tie this to a specific gateway.
Sub-claim "The mechanism enables transactions for amounts under 0.01 US…": 40% covered by S7 — S7 describes nanopayments and weighted payments, which imply very small amounts, but does not specify the threshold of under 0.01 USDC or the mechanism for achieving it.
Sub-claim "It provides a method for handling microtransactions in USDC.": 60% covered by S3, S4, S6, S7 — S3 and S4 discuss x402 payment rails and batched settlements suitable for microtransactions; S6 describes x402 as an agent payment rail for per-request payments; S7 discusses weighted nanopayments. Together, they indicate methods for handling microtransactions in USDC, but do not explicitly link to Circle's Gateway.
Coverage for the first three claims is below or near 0.5, primarily due to lack of explicit mention of Circle's Gateway and sub-cent thresholds. The skipped sources include one about low-risk DeFi (potentially relevant to stablecoin payments) and one from Coinbase (which partners with Circle on USDC). Both are low-cost and could fill gaps. Other skipped sources are off-topic. Given the remaining budget of 0.015, buying these two (total 0.007) is affordable and may improve coverage without overspending.

Final coverage assessment — The gathered sources provide no information about Circle's Gateway or its mechanism for settling sub-cent USDC payments. Sources discuss USDC generally, x402 payment rails, settlement latency, and idempotency, but none mention Circle's Gateway or sub-cent payment handling.

The provided sources do not contain information about how Circle's Gateway settles sub-cent USDC payments. None of the sources mention Circle's Gateway or describe a mechanism for settling sub-cent payments in USDC.
For context, the sources discuss USDC's general onchain settlement, the use of x402 for agent-to-agent payments, and weighted nanopayments for citation rewards, but these do not address the specific question about Circle's Gateway and sub-cent settlements.
