How the score works
What the score read on this service: status offline, 98% uptime 30d, 216ms response p95, x402 compliance 14 of 14, $0.001 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 Other, 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 50 listings, this one among them: the same 50 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 openx402 ($14.55, 18 tx) and coinbase ($1.59, 9 tx). Traction is a conservative undercount; first settlement seen 2026-09-07.
All measured facts
What it does
96 pay-per-call x402 services on Base USDC (x402 v2, exact scheme): DNS/SSL/security headers/domain checks, mainland-China vantage reachability probes, x402/A2A compliance audits, KYA trust registries, agent-commerce evidence packs, document and code generation APIs, free advisory APIs (Jevons pricing insight, compliance scans), original K-12 animated lecture packs, business landing-page delivery.
Verigrace x402 Store is a listed x402 Other 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 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.
