Sub-claim "Why is per-citation settlement considered fairer than a flat…": 30% covered by S1 — S1 states a fair model pays each cited source in proportion to its contribution, with heavily-relied-upon sources earning more and lightly-used ones less. This gives a fairness rationale for proportional per-citation payment, but it never mentions a flat per-fetch toll, so the comparative 'fairer than' claim is not directly supported.

Sub-claim "How does a flat per-fetch toll work, and how does per-citati…": 10% covered — No supplied passage describes how a flat per-fetch toll works. S1 describes per-citation weighted payment but does not contrast it with a flat per-fetch toll, so the mechanism and the difference are not answered.

Sub-claim "What fairness criteria or principles are used to compare per…": 20% covered by S1 — S1 supplies one principle—pay in proportion to contribution—but does not frame it as a criterion for comparing against a flat per-fetch toll, nor does it state any comparative fairness criteria.

Coverage is low on all three sub-claims, but none of the affordable skipped sources address per-citation settlement versus flat per-fetch tolls; their previews concern x402 timing, USDC settlement, idempotency, FX, and unrelated topics. Buying them would not fill the identified gaps, so no purchase is recommended.

Final check — "Why is per-citation settlement considered fairer than a flat…": 50% assessed by S1

Final check — "What fairness criteria or principles are used to compare per…": 0% assessed

Final coverage assessment — The supplied passages only directly support a fairness rationale for per-citation payment weighted by contribution (S1). They do not explain how a flat per-fetch toll works, do not contrast the two mechanisms, and do not state fairness criteria or principles for comparing them. S2 and S3 concern settlement recovery and latency, not the fairness comparison requested. The assessment does not establish a complete supported answer for every requested part.

Synthesizing a grounded answer from 3 source(s)…

Relevance review returned; only checked excerpts can retain support, and review cannot raise it.

Verified — S1 supports claim 1 at 60%: “A fair model pays each cited source in proportion to its contribution to the final answer.”

Verified — S1 supports claim 1 at 50%: “Heavily-relied-upon sources earn more; lightly-used ones earn less.”

Below reward gate — S1 supports claim 2 at 20%: “Weighted nanopayments make this granular settlement practical, and multi-author works can split a single reward across contributors automati…”

Confidence: Low — 2 sub-claims remain below the evidence threshold.

Onchain Micropayments Digest contributed 100% → reward $0.025

Paid $0.015 citation reward → Mara Okoye; Circle confirmed settlement even though the paid route acknowledgement failed.

Paid $0.01 citation reward → Devin Park; Circle confirmed settlement even though the paid route acknowledgement failed.

Done. Spent $0.025 across 2 confirmed/simulated payment(s) to creators.
