Cached source with perfect topical match (USDC instant settlement) and high reputation on this subject (41/100). Directly addresses the question's core claim; free to reuse. — the claim-aware portfolio chose a stronger, less redundant set inside the 4-source attention and $0.020000 fetch-budget caps, so this proposal stays unspent.
Cached and low price, but weak topical relevance to USDC settlement. Focuses on x402 agent payment rails, not stablecoin mechanics. Low citation history (40% on this subject). Minor supplementary value at best. — the free-preview coverage check could not connect this source to any sub-claim, so no toll is authorized.
Cached and cheap. Tangential: covers micropayment settlement floors, not USDC-specific instant settlement. Moderate reputation (42/100) but low direct relevance to the question's subClaims. — the free-preview coverage check could not connect this source to any sub-claim, so no toll is authorized.
Cached and cheap, but generic distributed systems topic (idempotency) with no direct stablecoin/USDC focus. Low relevance to the specific question about instant settlement mechanisms. — the free-preview coverage check could not connect this source to any sub-claim, so no toll is authorized.
Cached but completely irrelevant (gardening). Despite high past reputation, the topic mismatch means zero value for this crypto/stablecoin question.
Cached but irrelevant (retro gaming hardware). Despite high past reputation, the topic has no bearing on stablecoin settlement.
Cached and cheap. Directly relevant: discusses stablecoin payouts for workers, touching on settlement benefits. High reputation source (45/100) on this subject. Provides real-world adoption context. — the claim-aware portfolio chose a stronger, less redundant set inside the 4-source attention and $0.020000 fetch-budget caps, so this proposal stays unspent.
Cached and cheap. Tangential: Ethereum Foundation AI agents, not directly about USDC settlement mechanics. Decent reputation (50/100) but low direct relevance to the specific question. — the claim-aware portfolio chose a stronger, less redundant set inside the 4-source attention and $0.020000 fetch-budget caps, so this proposal stays unspent.
Cached but weak relevance. AI agents/semantic web topic doesn't address USDC or stablecoin settlement. High reputation (100/100) but off-topic for this question. — the free-preview coverage check could not connect this source to any sub-claim, so no toll is authorized.

Not cached, price 0.004. Ethereum DeFi discussion, not directly about USDC instant settlement. Could provide broader context but low direct relevance.
Cached and cheap. Coinbase blog about WSJ response (2022) is dated and not about settlement mechanics. High past reputation (45/100) but low relevance to the specific question. — the free-preview coverage check could not connect this source to any sub-claim, so no toll is authorized.
Cached and cheap. Russia crypto law is about regulation, not USDC settlement mechanics. Low relevance despite being stablecoin-related. Very low past reputation (2/100). — cached bytes are free, but this read does not clear the attention gate (EV 0.40, minimum 0.45, with a required claim target).
Not cached, but completely irrelevant (mystic/esoteric). No value for a technical crypto question.
