No deterministic risk flag. Risk fires only on an exact blocklist match, or a reserved-brand name with a mismatched verified payTo. Never from low uptime, a high price, or a model guess.

Attributed pro-quota: this payout address is shared, so volume is the operator-level figure divided by the services sharing it, while buyer and transaction counts stay whole. A declared convention, not an individually observed measure, and still a conservative undercount.
Currently sharing this payout address with Apple App Store Search, Reviews & App Data, Atlas Market Data, CoinGecko Crypto Price & Data (x402 Atlas), Crypto Perp Signals, DefiLlama Data API (x402 Atlas), DNS & WHOIS Domain Lookup, Email Auth Check (SPF/DMARC/DKIM), GDELT News Search and Timeline, Google Trends SEO Keyword Data, HTTP Security Headers Check, Hyperliquid Account Intelligence, Hyperliquid Market Data, Hyperliquid Prediction Markets Data (x402 Atlas), Image Optimizer & WebP Converter, Places & Local Business Search, Twitter/X Advanced Tweet Search, URL Unwrap / Redirect Tracer, Web Search, News & Page Reader, X (Twitter) Media Downloader.
Top buyer share is a concentration signal, not part of the ranking score.

] OVER TIME
All charts use the 30d selector; each series spans only the dates it has data for. Every series is also served as JSON at /api/v1/services/wikipedia-article-summary-mrtoqzsc-0/price, /scores, /volume and /buyers. On-chain volume and distinct buyers are measured over the service's settlement address and are a conservative undercount (only settlements that reach a measured facilitator are counted). The on-chain series roll up hourly, so the latest day can be up to about an hour behind; distinct buyers are counted per payout address, so a service that settles to more than one address is an upper bound.
checklist grew 11->14 on 2026-07-28; a step here is a metric change, not a regression
Measured site and economics pillars from the assessment history, so the latest value shown elsewhere on this page reads as a point on a trend rather than a permanent state.
Shared payout address (19 other services). These bars are the full shared address (operator-level), so do not sum them across the services that share it. Where a per-service figure is attributed, the assessment block and the ranking, it is the address total divided pro-quota by the 20 services sharing it: a declared convention, not an individually observed measure.
