Claim-aware portfolio selected 3/6 positive proposal(s): 3 cached + 0 fresh, predicting 2/2 claim(s) above the evidence floor with $0.000000/$0.015000 fetch USDC reserved.
Free-preview pre-check maps an actionable source to every sub-claim (2/2); paid reading may proceed within the budget.
Agent Economy Weekly has the highest reputation (47/100) and past citation rate (56%) on this subject. Its x402 payment rail article is directly relevant to how agents discover and pay for data sources. Already cached, so no cost. — selected for the claim-aware evidence portfolio (targets claims 1, 2; 0 fetch USDC, 1 attention slot).
CoinDesk article on AI agents as crypto's next billion users, paying with stablecoins, is highly relevant to discovery and payment. Reputation is moderate (16/100), but it's cached and on-topic. — selected for the claim-aware evidence portfolio (targets claims 1, 2; 0 fetch USDC, 1 attention slot).
Cointelegraph's article on Binance opening crypto trading to AI agents shows real-world discovery mechanisms. Reputation is moderate (12/100), but it's cached and provides a concrete example. — selected for the claim-aware evidence portfolio (targets claims 1, 2; 0 fetch USDC, 1 attention slot).
Stablecoin Ledger has strong reputation (30/100) and citation history (47%) on agent payments. Stablecoins are key for agent transactions. Already cached, reusing for free. — the claim-aware portfolio chose a stronger, less redundant set inside the 4-source attention and $0.015000 fetch-budget caps, so this proposal stays unspent.
Stripe Blog article on agents paying is topically perfect but has low reputation (2/100) and citation rate (5%). However, it's cached and cheap; the content matches the subclaim about evaluating payment methods. Worth reusing. — the claim-aware portfolio chose a stronger, less redundant set inside the 4-source attention and $0.015000 fetch-budget caps, so this proposal stays unspent.
Latent.Space has high reputation (22/100) and top weight (1.0). The ontologies article relates to how agents discover structured data sources. Already cached, high value for free. — the claim-aware portfolio chose a stronger, less redundant set inside the 4-source attention and $0.015000 fetch-budget caps, so this proposal stays unspent.
Arc Settlement Benchmarks has low reputation (10/100) but the x402 latency article is technical and relevant to evaluating payment source reliability. Already cached. — cached bytes are free, but this read does not clear the attention gate (EV 0.40, minimum 0.45, with a required claim target).
Web Payments Review's x402 finality article helps agents evaluate payment source speed. Reputation is low (6/100), but it's cached and supports the evaluation subclaim. — cached bytes are free, but this read does not clear the attention gate (EV 0.40, minimum 0.45, with a required claim target).
Distributed Systems Notes on idempotency keys is tangentially relevant to preventing double-spends in agent payments, but not core to discovery/evaluation. Cached, low opportunity cost. — cached bytes are free, but this read does not clear the attention gate (EV 0.30, minimum 0.45, with a required claim target).
Coinbase Cloud platform article is about developer tools, not directly about agent discovery/evaluation. Cached but low relevance. — the free-preview coverage check could not connect this source to any sub-claim, so no toll is authorized.
Ethereum Foundation Blog has zero citations on this subject and low relevance to agent discovery/evaluation. Although cached, not worth using time on.
Simon Willison's Weblog on AI model pricing is about cost competition, not agent discovery of data sources. Not cached, not worth purchasing.
Hugging Face blog on AI tutoring is completely off-topic. Not cached, skip.
Vitalik's DeFi article is about Ethereum's utility, not agent discovery of paid sources. Not cached, skip.
Decrypt article on crypto swap APIs has some relevance to payment methods but low reputation (9/100) and not cached. Not worth the $0.002 when better sources are available.
Inner Axiom article on ancient Greek rituals is completely off-topic. Cached but skip.
Conzit Labs RAG article is about document retrieval, not agent discovery of paid data sources. Not cached, not worth buying.
Retro Game Hardware article is off-topic. Cached but skip.
Gardening article is off-topic. Cached but skip.

Sub-claim "Autonomous agents discover paid data sources through automat…": 30% covered by S1, S3 — S1 mentions agents discovering and purchasing data autonomously at runtime via x402 HTTP 402 with machine-readable payment requirements. S3 indicates AI agents can access market data through Binance Agent OS. However, none of the gathered sources describe automated search of data marketplaces, APIs, or web directories, nor do they mention query languages or metadata standards.
Sub-claim "They evaluate paid data sources by automatically testing dat…": 10% covered by S1 — The gathered content focuses on payment rails and agent access, not on evaluation. S1's machine-readable payment requirements could be seen as a lightweight price/requirement check, but there is no evidence of data-quality testing, licensing checks, price comparison, or provider-reliability/reputation/trial assessment.
Coverage is low for both sub-claims. Only 'Latent.Space — Ontologies Are So Back' appears both affordable and relevant to the discovery gap, specifically regarding metadata standards and query languages. No skipped source directly addresses the evaluation gap, so only that one source is recommended to remain frugal.

Final coverage assessment — The gathered sources focus on agent payments, market data access, and ontologies, but they do not substantively explain how autonomous agents discover paid data sources or how they evaluate them for quality, licensing, price, or reliability.

Autonomous agents discover paid data sources through mechanisms like HTTP 402 status codes, which allow them to autonomously pay per request at runtime without needing accounts or API keys. They evaluate these sources by using ontologies to understand data structures and relationships, which provide logical guardrails for agentic systems.
Evidence ledger — quotes verified before rewards
Autonomous agents discover paid data sources through automated search of data marketplaces, APIs, and web directories, often using query languages and metadata standards.
