Sub-claim "Nanopayments via x402 reduce gas costs by enabling off-chain…": 70% covered by S5 — S5 explicitly states that nanopayments sign off-chain authorizations and settle in batches, reducing gas costs. However, details on how x402 specifically enables this are limited.

Sub-claim "Autonomous agents can query databases without incurring per-…": 40% covered by S4 — S4 describes x402 as a payment rail where agents pay per request without accounts, but does not explicitly state that per-query gas fees are avoided. The connection to database queries is weak.

Sub-claim "x402 aggregates payments, reducing the number of on-chain tr…": 60% covered by S1, S5 — S1 mentions batched settlements, and S5 discusses settling many micro-authorizations together. However, the term 'aggregates payments' is not explicitly used.

Sub-claim "Lower gas costs make frequent database queries economically …": 30% covered by S4 — S4 discusses budgets and emergent frugality, but does not directly link lower gas costs to feasibility of frequent queries. The claim is only weakly supported.

Claims 2 and 4 have low coverage. The Stripe Blog and Ethereum Foundation Blog are affordable (0.002 each) and likely contain relevant technical details on x402 and gas costs. Other sources are either too expensive or less relevant.

Synthesizing a grounded answer from 7 source(s)…

⚖️ Sources disagreed on x402 payment settlement latency — S1 x402 batched settlements finalize in roughly 180 milliseconds (median 178ms, p95 240ms) on Arc testnet. vs S2 An x402 payment takes about 15 seconds to settle, similar to an Ethereum L1 block time, because each payment is its own transaction. → trusted S1 (S1 provides specific benchmark data from actual testnet measurements (median 178ms, p95 240ms), while S2 describes a scenario where each payment is a separate on-chain transaction, which contradicts the batching mechanism described in S5. S1's data is more precise and internally consistent with the batching approach.)
