> ⚠ Low confidence — Each summary sentence is tied to a verbatim excerpt and model-checked; completeness and independent factual correctness remain unverified. Evidence assessment: 3 sub-claims remain below the evidence threshold. Treat this as provisional.
Model-written summary with sentence-level citations. Each sentence is followed by the verbatim source text it was checked against; sentences without a qualifying excerpt were removed.
Research target 1
Requested topic (unverified): “What are Keryx access tolls and how do they work?”
An access toll is a payment that purchases a read through the source's x402 endpoint. Source text: “An access toll purchases a read through the source's x402 endpoint.”
Research target 2
Requested topic (unverified): “What are Keryx citation rewards and how do they work?”
A citation reward is a separate payment considered after the answer is written and its evidence checked. Source text: “A citation reward is a separate payment considered after the answer is written and its evidence checked.”
Research target 3
Requested topic (unverified): “What published source material provides concrete examples of Keryx access tolls?”
The published first-party engineering documentation states that an access toll purchases a read through the source's x402 endpoint. Source text: “An access toll purchases a read through the source's x402 endpoint.”
Evidence gap: the recorded assessment remains below the support threshold for this target.
Research target 4
Requested topic (unverified): “What published source material provides concrete examples of Keryx citation rewards?”
The published first-party engineering documentation states that a citation reward is a separate payment considered after the answer is written and its evidence checked. Source text: “A citation reward is a separate payment considered after the answer is written and its evidence checked.”
Evidence gap: the recorded assessment remains below the support threshold for this target.
Research target 5
Requested topic (unverified): “How do access tolls and citation rewards compare in a concrete example from published source material?”
In the published documentation, when no citation qualifies, the citation pool stays unspent while access tolls already settled remain paid, showing that access tolls are paid regardless of citation rewards. Source text: “When no citation qualifies, the citation pool stays unspent, while access tolls already settled remain paid.”
Evidence gap: the recorded assessment remains below the support threshold for this target.
Summary sentences are model-written and model-checked, not independently verified; they claim no more than their excerpts and are not a complete synthesis. Excerpts establish source grounding, not that a source is correct. Source statements may be wrong or conflicting. Payment states remain in the separate receipt.

Breaking down: "Can you give a concrete example of Keryx access tolls versus citation rewards using published source material?"
Identified 5 research target(s) to investigate; these are not established facts
Deep mode: up to 5 paid/cached/public reads plus one bounded gap-expansion pass when needed.
Web search: 6/6 planned queries attempted, 4 succeeded, 24 public page previews/leads, 2 unavailable queries. Previews and supplied URLs are discovery only. Public reads spend no USDC; model and service operating costs remain separate.
Discovered 2 verified creator source(s) and 54 free public reference(s)
Claim-aware portfolio (exhaustive; bounded selection, not a claim of global optimality) selected 2/4 positive proposal(s): 2 free/cache selections + 0 paid fresh selections, predicting 5/5 claim(s) above the evidence floor with $0.000000/$0.025000 fetch USDC reserved.
Free-preview pre-check maps an actionable source to every sub-claim (5/5); paid reading may proceed within the budget.

Sub-claim "What are Keryx access tolls and how do they work?": 80% covered by S1, S2 — S1 explicitly defines an access toll as a purchase of a read through the source's x402 endpoint, and notes cached content can avoid a new toll. S2 confirms access tolls are separate charges and a spending allowance permits spending within limits. Missing: exact mechanics of x402 endpoint interaction or fee calculation, but core definition and separation are covered.
Sub-claim "What are Keryx citation rewards and how do they work?": 90% covered by S1 — S1 explains citation rewards are separate payments after answer writing and evidence checking, with qualification conditions (marker in answer, synthesis declaration, validated quotation support >=0.4), allocation from citation pool using integer micro-USDC, and unspent pool if no qualifying citation. S2 adds reward eligibility depends on content cited and payment evidence. Missing: exact payout authority details beyond 'source's authoritative payment terms', but overall mechanism well covered.
Sub-claim "What published source material provides concrete examples of…": 60% covered by S1, S2 — S1 and S2 are published source material (GitHub engineering doc and Keryx terms of service) that describe access tolls, but they provide definitions and operational context rather than a specific concrete example with numbers or a named source. No explicit example of a particular toll amount or transaction is given.
Sub-claim "What published source material provides concrete examples of…": 60% covered by S1 — S1 is published source material describing citation rewards and their allocation, but again no concrete example with specific reward amounts or a named rewarded creator. It explains the mechanism but lacks a concrete instance.
Sub-claim "How do access tolls and citation rewards compare in a concre…": 50% covered by S1 — S1 explicitly contrasts access tolls and citation rewards: toll purchases a read, reward is separate after evidence check; cached content avoids toll but can still earn reward; paid read does not guarantee reward; unspent citation pool remains while tolls stay paid. However, no concrete example with specific figures or a named source is provided, so the comparison is conceptual rather than instantiated.
The gathered sources provide strong conceptual coverage of access tolls and citation rewards, but the question specifically asks for a concrete example using published source material. The current sources describe mechanisms without specific instances. The skipped source 'Keryx owner release notes — first-party validation — Keryx v0.27.63' is a first-party Keryx publication that may contain concrete examples or operational details, and its price (0.005) fits within the remaining budget (0.025). Other skipped sources are either irrelevant to Keryx or generic academic material unlikely to provide Keryx-specific concrete examples. Buying this one source is a frugal attempt to fill the concrete example gap.
Filling gap — reused cached Keryx owner release notes — first-party validation — Keryx v0.27.63 (free) — S3

Final coverage assessment — The gathered sources provide first-party documentation and terms of service for Keryx. S1 explicitly defines access tolls and citation rewards, their separation, and the conditions for citation rewards. S2 confirms that access tolls and citation rewards are separate charges and that reward eligibility depends on cited content. S3 is a release note with no concrete examples. No source provides a concrete published example with specific amounts or a worked comparison; the question asks for a concrete example using published source material, which is not present. The assessment does not establish a complete supported answer for every requested part.
Synthesizing a grounded answer from 3 source(s)…

Source-matched public excerpt (no creator reward) — S1, research target 2, proposed support 100% (estimate, not entailment): “A citation reward is a separate payment considered after the answer is written and its evidence checked.”

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.
Recorded purchase outcomes
Did the exact article versions bought for this answer appear in its citations? This view scores retained BUY decisions against payment observations recorded in the same dispatch trace.
Recorded settlement bookkeeping only; Circle and chain settlement have not been independently rechecked here.
This is a partial retained trace sample, not a full payment ledger. An absent matching payment does not prove that no payment occurred; excluded and unconfirmed costs remain unknown.
