The verification ledger
Every figure on this site traces to a stored fact with an official source URL and a verification date. This page is the ledger of that store: 371 cited facts —223 about 27 providers, 148 about 26 markets — of which 371 carry the source's own wording verbatim. The whole dataset is downloadable at /facts.json.
Verification dates range from 2026-07-11 (oldest claim still standing) to2026-07-30 (most recent re-confirmation).
What "verified" means here
A fact enters the store with three parts: our one-line summary, the exact URL it was read from, and — wherever the page yields one — the source's own sentence, stored verbatim. A checker then re-reads each cited URL and searches the live page (visible text first, then the raw document for figures that live in data islands) for that stored wording. Only an exact match moves the verification date forward; the checker never rewrites a value. A fact whose wording has vanished from its source is flagged as drifted and re-sourced or dropped by a human pass — it does not keep a fresh date it no longer earns.
Pages display the OLDEST verification date among the facts they cite — "nothing here is older than this" — rather than the newest, which would over-claim. The same rule orders this page's range above.

Using the dataset
/facts.json carries every row of this ledger with a stableid, so a consumer can diff runs instead of scraping prose. Values are strings end to end — a withdrawal fee of 0.00000237 survives the round trip. Fee MOVEMENTS between reads are a separate, append-only surface:/changes with feeds at /changes.jsonand /changes.xml. The rules every published page must pass are described on the methodology page.
