Sub-claim "How does volatile-token risk affect spending-cap design deci…": 10% covered — No supplied passage addresses volatile-token risk or its effect on spending-cap design. S1 describes x402 payment rails and S2 describes USDC's stable settlement, which is topical context (a stablecoin avoids volatility) but neither discusses volatility risk nor cap design. S3 covers quoting, buying, recovery, ceilings, and reconciliation for a paid research job, but never mentions token volatility or how it should shape a cap.

Sub-claim "How should spending caps for an agent be designed when the t…": 10% covered — No passage gives any procedure for designing caps under token volatility. S3 mentions an 'all-in ceiling' including service fee and creator budget and checks against a creator cap, but does not address volatile tokens, price fluctuation, or cap-adjustment mechanics. S1 and S2 are about payment rails and stablecoin settlement, not cap design under volatility.

Both sub-claims are essentially uncovered (0.1 each): the gathered sources explain payment rails, stablecoin settlement, and a paid-job lifecycle, but none addresses volatile-token risk or how it should affect spending-cap design. Several affordable skipped sources are topically relevant to agent payment mechanics and could partially fill the gap: 'Onchain Micropayments Digest — Nanopayments and the $0.000001 floor' ($0.005) and 'Arc Settlement Benchmarks — Measuring x402 settlement latency on Arc' ($0.003). Both fit the remaining $0.015 budget. Other skipped items (idempotency keys, Stripe Link AI spending, stablecoin adoption surveys, x402 finalization overview) are less directly on-point for volatility-driven cap design, so they are not prioritized. Note: even these purchases may not fully answer the volatility/cap-design question, since none is explicitly about volatile-token risk and cap sizing.

Final coverage assessment — The gathered sources describe payment rails, stablecoin settlement, a buyer client's spending-cap mechanics, and nanopayment batching, but none directly addresses how volatile-token risk should shape spending-cap design for a paid research agent. S3 is the closest: it mentions an 'all-in ceiling' including service fee and creator budget, and checks a payment policy before buying, but it does not discuss token volatility, price fluctuation, or how volatility should affect cap design. S2 notes USDC is a dollar stablecoin, which is topical context for avoiding volatility, but does not answer the design question. S1 and S4 cover payment rails and micropayment floors without volatility or cap design. Thus both sub-claims lack a direct answer. The assessment does not establish a complete supported answer for every requested part.

Below reward gate — S1 supports claim 1 at 0%: “Agents can therefore pay per request with no accounts or API keys, discovering and purchasing data autonomously at runtime.”

Below reward gate — S3 supports claim 2 at 0%: “The independent Keryx buyer client separates quoting, buying and recovering a research job.”

Below reward gate — S3 supports claim 2 at 30%: “The all-in ceiling includes both the service fee and creator budget.”

Below reward gate — S3 supports claim 2 at 20%: “The client uses the caller's already-funded wallet; it does not automatically fund or deposit for it.”

Below reward gate — S3 supports claim 2 at 30%: “The buy command obtains a fresh quote, checks the payment policy again, writes a durable job journal, signs once and submits once.”
