VERDICT

ranking generation 3

solid 81/100 #71 of 113 in Verification by measured score

What the score read on this service: status online, 99.9% uptime 30d, 929ms response p95, x402 compliance 14 of 14, $2 price against the category, on-chain traction measured. Each of those is measured, and each is published in full below.

The score comes from our own monitoring, never from reviews, operator claims, or a language model: reliability, x402 compliance, price against the category, a deterministic risk flag, and a small on-chain traction term, weighted by ranking generation 3. It is not placement anyone can buy: the paid verify tier is reported beside it and is not one of its inputs. Every component below stays published and read-only.

It is a score inside Verification, and only there: price and speed are scored against the whole category field, every listing in it that carries no danger flag, the scored service included, which here means 113 listings, this one among them. That set is wider than the 113 the position above is counted against, because a listing we have measured too little of to rank still sits in the field the price and the speed are normalized over. The same service in a different field would read differently. The same engine answers GET /api/v1/best, and asked for a different pool (the whole directory, or another filter) it returns a different number for this service under this same ranking generation. Neither is more correct: they answer different questions, and the methodology states which is which.

Bands on the 0 to 100 measured score: strong at 93 and above, solid from 75, mixed from 55, weak below 55. Price and speed are scored against the whole category field, every listing in it that carries no danger flag, the scored service included, so the score places a service in its own field.

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 AeroCheck, AgriPulse, CascadeWatch, ComputePulse, ConsumerPulse, CopperheadAI, CrownBlock, CyclePulse, DeFiRisk, DocEdge, Floyd Coding Agent, FundingRates, GovEdge, GridPulse, IndustrialMetals, LaborPulse, LatAmPulse, LeaseEdge, LoneStarOracle ChainScout, LoneStarOracle ContractCheck, LoneStarOracle EarningsCalendar, LoneStarOracle EquityScope, LoneStarOracle GeoPulse, LoneStarOracle InsiderFlow, LoneStarOracle Liquidations, LoneStarOracle MacroPulse, LoneStarOracle NewsSentiment, LoneStarOracle OptionsFlow, LoneStarOracle PortfolioRisk, LoneStarOracle TokenLaunch, LoneStarOracle TokenScope, LoneStarOracle WealthPulse, LoneStarOracle WeatherOracle, LoneStarOracle WhaleAlert, OpenInterest, RattlerAI, RealEstatePulse, RWA Risk, StablePulse, StakeEdge, StrategicMaterials, SupplyChainPulse, TechAnalysis, TradePulse, WalletRisk.

Top buyer share is part of the ranking score: a higher share lowers the traction part of the score, by up to half when one address holds all 30d volume.

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/cottonmouthai/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.

PILLARS OVER TIME (measured)

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 (45 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 46 services sharing it: a declared convention, not an individually observed measure.

Shared payout address (45 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.
