How the score works

What the score read on this service: status online, 99.9% uptime 30d, 395ms response p95, x402 compliance 14 of 14, $0.01 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.

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.

It is a score inside Data, 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 362 listings, this one among them: the same 362 the position above is counted against. When the two differ, the field is the wider one, 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.

Settled via payAI ($2.62, 145 tx). Traction is a conservative undercount; first settlement seen 2026-09-20.

All measured facts

What it does

santyvv-data is a listed x402 Data API. Captured payment terms name Base. Monitoring and settlement figures below describe the observations available to this directory; an unpaid HTTP 402 check does not prove that a paid call will deliver.

Assessment computed at 2026-10-10 11:33:01 UTC. Latest service check observed at 2026-10-10 17:00:15 UTC. Service data JSON · Measurement methodology.

Page rendered at 2026-10-10 17:08:55 UTC. This response time is separate from the observation and computation times attached to each measurement.

Latest endpoint observation: 2026-10-10 17:00:15 UTC. Latest price capture: 2026-09-23 10:25:36 UTC. Prices are recorded quotes, not a promise of availability. Token assets and payment terms are listed separately. Endpoint data JSON · Price history JSON · Measurement methodology.

Assessment computed at 2026-10-10 11:33:01 UTC. Uptime uses the stated daily-rollup window; response times are in milliseconds, compliance is passed/evaluated checks, and traction is a measured settlement floor. The comparison score is out of 100 within this category. Assessment JSON · Measurement methodology.

Observed daily coverage: 2026-09-11 to 2026-10-10 UTC. Daily monitoring and settlement rollups do not expose their computation time; a bucket date is not an update timestamp. Latest settlement in the assessment: 2026-10-08 05:41:49 UTC. Uptime and response JSON · Volume JSON · Buyers JSON · Measurement methodology.

Ranked from the measured category pool, refreshed at most once a minute. The comparison has no persisted computation timestamp; the assessment time above belongs to this service only. Ranking API documentation · Ranking methodology.

Assessment volume uses the latest 30d assessment. Over time sums daily address snapshots, rounded to cents and refreshed separately. The two sources can differ in timing, precision and shared-address attribution. Amounts use cents for comparison; known sub-cent values keep up to 12 significant digits. The exact stored assessment value is shown above.

Conservative undercount: only USDC settlements via facilitators we measure are counted. A measured floor, not an estimate.

Top buyer share lowers the on-chain traction part of the ranking score behind this page's verdict and /best, by up to half when one address holds all 30d volume. The Recommended and Highest volume sorts of the services list do not use it; they use the Concentrated volume rule instead.

Scores: one day per column, 09-11 to 10-10*, on the columns of Response time. Uptime held below 100% on some days in this window, including any partial day. Daily readings remain in the Uptime strip and Values. The checklist grew from 11 to 14 checks on 2026-07-28, before this window. Pillar lines use their own low and high. Exact dated readings are available in each readout and in Values.

Each series spans only the dates it has data for. Every series is also served as JSON at /api/v1/services/santyvv-data/price, /scores, /volume and /buyers.

Values

* today so far, partial (UTC).

The uptime summary counts completed UTC days only. The strip, readouts and table retain today's partial reading.

Daily snapshot total, 30d: $2.62, peak $1.67 on 09-20. The visible 30d total in Traction comes from the latest assessment. These sources can differ in their window, refresh time, cent rounding and shared-address attribution.

Daily address snapshots: 2026-09-11 to 2026-10-10 UTC; * today so far, partial (UTC). Daily snapshots store cents. A recorded $0.00 with settlements cannot distinguish exact zero from volume rounded away. Lost precision is unavailable here.

Settlement volume uses the stored USD valuation of tracked payments; it is distinct from token quantities. USD-pegged assets are valued at 1 USD per token in these rollups. The measured settlement floor does not cover all payments to this service.

Assessment history last recorded at 2026-10-10 11:33:01 UTC. Each UTC day uses its last recorded run; missing readings stay unmeasured. Assessment history JSON · Measurement methodology.
