ASSESSMENT

updated 4h ago

Evidence-backed signals, not a single score. Click any chip for the proof. Measured values stay read-only; unknown is honest.

reliability 99.5%

uptime 24h: 100%
uptime 7d: 98%
uptime 30d: 99.5%
uptime 90d: 99.5%
response p95: 1364ms
avg response: 812ms
total checks: 2,084

Measured on the unpaid 402 handshake, not the paid call. A service can 402 correctly and still fail after payment.

compliance A (14/14)

14 of 14 x402 conformance checks pass. Full checklist below.

risk clean

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 24h 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.

price percentile in Data

site signals present (of 6)

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.

VOLUME (on-chain settlement, USD)

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.

DISTINCT BUYERS

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. Per-service buyer and transaction counts are shown whole (integers), not divided; only volume is attributed pro-quota. A declared convention, not an individually observed measure.
