Claim-aware portfolio selected 2/2 positive proposal(s): 2 cached + 0 fresh, predicting 3/4 claim(s) above the evidence floor with $0.000000/$0.015000 fetch USDC reserved.
Free-preview pre-check covers 3/4 sub-claims (75%). The agent may buy only claim-targeted sources and will label the answer provisional if paid evidence stays thin.
Top reputation; preview explicitly covers per-citation payments weighted by contribution, directly addressing claim 1 (citation weights) and claim 2 (combining with x402). Already cached, so reuse free. — selected for the claim-aware evidence portfolio (targets claims 2, 3; 0 fetch USDC, 1 attention slot).
Good reputation; preview directly explains x402 as an agent payment rail, core to claim 0 (x402 access tolls) and claim 2 (combining with weights). Already cached, so reuse free. — selected for the claim-aware evidence portfolio (targets claims 1, 3; 0 fetch USDC, 1 attention slot).
High reputation and cited often on this subject; preview mentions USDC settlement, directly relevant to claim 3 (payouts in USDC) and claim 0 (payment flow).

High reputation but preview is about Coinbase responding to WSJ, not about USDC payouts or Keryx mechanisms. Already cached but low relevance.
Low reputation; preview about Fed and crypto firms is regulatory news, not relevant to Keryx's payment flow. No relevant targets.
Moderate reputation; preview mentions stablecoins and creator payments (X paying creators), which is loosely relevant to claim 3 (USDC payouts), but not specific to Keryx. Already cached but low expected value.

Final coverage assessment — The gathered sources discuss generic x402 payment rails and weighted citation payments, but they never mention Keryx, USDC, or any concrete mechanism for combining tolls and citation weights into creator payouts. All specific subclaims remain unsupported.
Synthesizing a grounded answer from 2 source(s)…
No citation passed the evidence gate — the $0.015000 citation pool stays unspent; settled access tolls still stand.
Drafted answer citing 0 source(s)
Confidence: Low — no citation passed the evidence gate.
Done. Spent $0 across 0 confirmed/simulated payment(s) to creators.
Payouts to cited creators appear here.
The provided sources do not contain information about Keryx specifically, nor how it uses x402 access tolls and citation contribution weights to pay creators in USDC. Therefore, I cannot answer the question about Keryx based on these sources.

One deterministic JSON bundle binds the answer, visible decisions, exact article versions, claim evidence and a Circle-settlement snapshot under SHA-256. Retain the digest to detect later changes; the self-check is not a publisher or Keryx signature.
