How the score works

What the score read on this service: status online, 99.9% uptime 30d, 380ms response p95, x402 compliance 12 of 12, price not captured, no known payTo, so no on-chain traction to read. 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.

All measured facts

What it does

Pay-per-call API merchant selling web extraction, link checking, domain intelligence, web search, geoIP, and Nano blockchain data · all settled in Nano (XNO) via x402 protocol. Instant, feeless, green peer-to-peer payments on nano:mainnet.

Vend API Merchant is a listed x402 Data API. No payment network has been captured yet. 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.

Page rendered at 2026-10-10 16:58:46 UTC. This response time is separate from the observation and computation times attached to each measurement.

Latest endpoint observation: 2026-10-10 16:56:03 UTC. Latest price capture: 2026-09-21 11:08:59 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 11:33:02 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.
