Open data

What the service holds, how fresh it is, how often it is right, and who uses it

Two kinds of number. The first block is read live from the same endpoints anyone can call. The second is typed in by hand on the date shown, in the manner of healthchecks.io's about page, because a one-person service earns trust by publishing the numbers it would rather round up.

Live from the API

organization-to-domain pairs in the warehouse (/stats)
distinct organizations named in OV/EV certificates
distinct registrable domains

Warehouse data as of (the date of the newest certificate in it; the sync itself runs daily). The research refresh that rebuilds the notes, the answer pages and the JSON below runs weekly.

From the weekly research refresh

Read from coverage.json and vendor_customers_profile.json, the same files the notes are built from.

MeasureValueMeaning
Period observedcontiguous months in the warehouse; the first and the current month are partial
Certificates in the last complete monthdistinct certificates (one fingerprint counted once, however many of the log sources carried it)
Gold pairs (Wikidata LEI ↔ domain)the set resolution is scored against; skews to large listed companies
  absent from the OV/EV warehousecoverage, not error: the domain has no organization-validated certificate
  present, name matches the gold LEI exactlythe resolution the product makes
  present, name matches looselycontainment only; note 1 counts it as weaker evidence and never assigns an LEI on it
  present, LEI missing from this GLEIF snapshotthe gold LEI is no longer in the register snapshot the run used; usually a merger or a lapsed registration
  present, certificate names something elsea registered-name disagreement, not an error rate: note 1 decomposes it, and most are the owner's own group or a vendor's certificate on the owner's domain
Confirmed vendorsvendors whose customers note 3 profiles
Customer domains across themdomains carrying a confirmed vendor's certificate without its brand
  resolved to one legal entitythe rows that carry an LEI

By hand, as of 2026-09-07

Counted from the service's own tables and the verification set on that date. Updated when something changes, with the date moved.

What is deliberately not here

Per-key or per-customer detail, query contents, and anything from a source that is not public. The privacy section says what is logged and for how long; the research notes say how each measure is defined and where it fails.
