Cointelegraph.com News has moderate citation rate (29%) and reputation (12/100); cached and covers Binance's Agent OS for agent discovery of crypto services. — 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 low citation rate (14%) but high weight (1.0) and reputation (14/100); cached and covers ontologies for agent systems, relevant to evaluation via metadata/schema. — 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.
Simon Willison's Weblog is about local model running, not agent data source discovery/evaluation; low relevance and not cached, so not worth buying.
Hugging Face Blog covers Gradio workflows for ML, not agent discovery of paid data sources; not cached and low topical fit.
Vitalik Buterin's site covers low-risk DeFi, not agent data source discovery; not cached and off-topic.
Coinbase Blog has zero citations for this subject; cached but covers user protection, not agent discovery; low relevance.
CoinDesk has low citation rate (29%) and reputation (15/100); cached but covers crypto policy, not directly agent discovery; low topical fit. — the free-preview coverage check could not connect this source to any sub-claim, so no toll is authorized.
Inner Axiom is esoteric/occult content, completely off-topic for agent data source discovery; not cached.
Conzit Labs covers robotics data generation, not agent discovery of paid data sources; not cached and low relevance.
Arc Settlement Benchmarks has low citation rate (17%) and reputation (5/100); cached and covers x402 settlement latency, relevant to evaluation of payment integration options. — 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 has low citation rate (13%) and reputation (3/100); cached but covers x402 timing, marginally relevant to payment evaluation. — cached bytes are free, but this read does not clear the attention gate (EV 0.30, minimum 0.45, with a required claim target).
Distributed Systems Notes covers idempotency keys, which is technical infrastructure for reliable agent payments, but cached and tangentially relevant to payment integration. — cached bytes are free, but this read does not clear the attention gate (EV 0.40, minimum 0.45, with a required claim target).
Retro Game Hardware is about console repair, completely off-topic; cached but not relevant.

Final coverage assessment — The gathered sources focus on payment infrastructure and mechanisms for autonomous agents (e.g., x402, stablecoins, nanopayments) but do not address how agents discover or evaluate paid data sources. None of the sources mention data marketplaces, API directories, metadata analysis, test queries, licensing, rate limits, or related topics. Therefore, the sub-claims are not covered.

The supplied sources do not describe a general workflow for discovering and evaluating paid data sources (e.g., searching marketplaces, inspecting metadata, running test queries, checking licensing). Instead, they describe a runtime discovery-and-payment mechanism: x402 turns HTTP 402 into a payment rail where a server responds with machine-readable payment requirements, the client signs a payment authorization and retries, letting agents "pay per request with no accounts or API keys, discovering and purchasing data autonomously at runtime." For evaluating whether to pay, the sources emphasize preconditions for sound spending: agents need a stable unit of account—"Dollar stablecoins like USDC let an agent price expected value against cost in stable terms, which is a precondition for rational spending decisions" —and nanopayment rails so that very small costs are viable, as "many micro-authorizations settle together" making "paying a creator a fraction of a cent per citation actually viable" . Subclaims about metadata, sample data, user reviews, automated test queries, licensing terms, and rate limits are not supported by these sources.
Evidence ledger — quotes verified before rewards
Autonomous agents discover paid data sources by searching data marketplaces, API directories, and web indexes for relevant datasets.
