How the score works
What the score read on this service: status online, 100% uptime 30d, 194ms 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 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 170 listings, this one among them: the same 170 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 coinbase ($238.63, 177 tx). Traction is a conservative undercount; first settlement seen 2026-07-22.
All measured facts
What it does
scvd.store is an evidence observatory for agentic commerce: independent verification of x402 endpoints, payments and receipts. Before an agent pays an x402 endpoint, we check that it can be paid. After it pays, we check the signed receipt. Over time we watch endpoints and publish a dated, signed corpus. Sellers use it to prove a door works; buyers use it before spending. Every artifact is signed, expires, and names what we did not see. Not escrow, not a rating, not a guarantee. Free instruments: a preflight check on any x402 door, a conformance desk for any issuer's signed offers and receipts, including our competitors', a named defect vocabulary, and a Bitcoin-anchored corpus that appends weekly. Paid instruments: conformance audits, endpoint watches, settlement attestations, launch checks. Never a ranking, and never a verdict without its derivation and denominator beside it. Operated by Record Creative Co. LLC.
scvd.store · evidence observatory for the x402 economy is a listed x402 Verification API. Captured payment terms name Arbitrum One, Base, Polygon, Solana. 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.
Concentrated volume is one rule applied to every listed service: the 3 largest paying addresses hold at least 90% of 30d volume, with at least $10 of volume and 50 settlements in the same 30 days. While it applies, this service's volume counts as 0 in the Recommended and Highest volume sorts of the services list. The label says where the payments came from, not why.
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.
