Claim-aware portfolio selected 1/1 positive proposal(s): 1 cached + 0 fresh, predicting 1/1 claim(s) above the evidence floor with $0.000000/$0.002500 fetch USDC reserved.
Free-preview pre-check maps an actionable source to every sub-claim (1/1); paid reading may proceed within the budget.
First-party Keryx engineering notes are the most direct source on what Keryx actually provides (citation rewards, evidence checks, buyer recovery, USDC/x402 research flow). Already cached, full text, cheapest tier, and the only candidate whose preview speaks to Keryx's own data/behavior. — selected for the claim-aware evidence portfolio (targets claim 1; 0 fetch USDC, 1 attention slot).
Stablecoin Ledger's abstract is about USDC onchain settlement speed, not about what data Keryx provides; only tangential context and low past citation rate (22%).
Agent Economy Weekly covers the x402 payment rail generally, not Keryx's data offering; useful background at best and redundant with the first-party note.
Micropayment/nanopayment floor discussion is about settlement economics, not Keryx's provided data; no direct link to the subclaim.
Idempotency keys in distributed systems is unrelated to what data Keryx provides; prior read on this subject was never cited.
Gardening content, wholly off-topic for Keryx data.
Retro console repair, wholly off-topic.
Stripe fraud data at AI startups concerns payments risk, not Keryx's data offering; no target support.
Ethereum Foundation AI-agent triage post is about protocol security work, not Keryx data; tangential at best.
New York crypto-mining moratorium news is unrelated to what data Keryx provides.
Latent.Space on ontologies for agents is about agent design, not Keryx's data; no direct support for the subclaim.
Metadata-only Simon Willison post on Anthropic model adoption; no text and off-topic for Keryx data.
Metadata-only Hugging Face post on agent memory; no preview text and unrelated to Keryx's data.
Metadata-only Vitalik post on low-risk DeFi; no text and not about Keryx data.
Coinbase response to WSJ is about proprietary trading allegations, not Keryx data.
Decrypt Russia crypto-law piece is unrelated to what data Keryx provides; Decrypt has never been cited on this subject.
CoinDesk dollar-vs-euro onchain gap is stablecoin market analysis, not Keryx's data offering.
Esoteric soul cosmology, wholly off-topic.
Conzit piece on SpaceX AI data centers is unrelated to Keryx data; prior read on this subject was never cited.
Arc x402 settlement latency benchmarks are about settlement performance, not what data Keryx provides; never cited here before.

Reused cached Keryx Engineering (first-party) — Recovering a Keryx paid research job (free) — S1
Sub-claim "What data does Keryx provide?": 10% covered by S1 — S1 describes the Keryx buyer client's workflow (quoting, buying, recovering a research job; treasury payee; all-in price ceiling; caller-funded wallet) and mentions inspecting 'the research result and its economics,' but it never specifies what data Keryx actually provides. It references a research-package.ts file and buyer-agent.md, but the passages do not enumerate or describe the data contents. This is topical context about the buyer process, not an answer to what data Keryx provides.
Coverage for the sole sub-claim is below 0.5, but none of the skipped sources address what data Keryx provides—they cover unrelated topics (USDC settlement, x402, nanopayments, idempotency, gardening, retro hardware, fraud stats, Ethereum triage, mining bans, ontologies, AI models, agent memory, DeFi, Coinbase, Russian crypto law, euro stablecoins, esoteric cosmology, SpaceX data centers, x402 latency). No affordable skipped source would fill the gap, so no purchase is recommended.
Final check — "What data does Keryx provide?": 10% assessed by S1
Final coverage assessment — The only supplied source is a first-party engineering note about recovering a Keryx paid research job. It describes buyer-side mechanics (quoting, buying, recovering, treasury payee, price ceiling, wallet usage) and mentions that buyers should inspect the research result and its economics, but it does not state what data Keryx provides. No passage enumerates or describes the data delivered by Keryx. The assessment does not establish a complete supported answer for every requested part.
Synthesizing a grounded answer from 1 source(s)…
Relevance review returned; only checked excerpts can retain support, and review cannot raise it.
Below reward gate — S1 supports claim 1 at 0%: “Buyers should inspect both the research result and its economics before judging the outcome.”
Below reward gate — S1 supports claim 1 at 20%: “The independent Keryx buyer client separates quoting, buying and recovering a research job.”
Rejected 0 invalid evidence span(s) and 1 unsupported citation marker(s); rejected markers cannot receive citation rewards.
No citation passed the evidence gate — the $0.002500 citation pool stays unspent; settled access tolls still stand.

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 supplied source does not describe the specific data that Keryx provides. It only indicates that a Keryx buyer client handles a "research job" and that buyers should inspect "both the research result and its economics". The passages do not enumerate the contents, fields, or format of the data Keryx delivers, so that part of the question remains unanswered.
