This registry is published as data, not only as pages. 260 venues across 4 countries, 78 of them with a price read off the venue's own rates page and quoted verbatim. Free to use, attribution asked, no key required.
A link is proposed by machine and promoted by a person; no script may mark a venue verified. A price is only published when it was read on the venue's own rates page, and every amount must appear verbatim in the evidence quote stored beside it, or the build fails rather than degrade.
So the honest limits: coverage is deliberately narrow and grows by hand. A page we could not reach is recorded as unreachable, never as a changed price. Where a venue prints two prices in one cell we publish neither as a machine-readable offer, because nothing here says which one applies.
Every venue has a permanent name of the form officiallink:country/slug. It is a name, not an address: a venue moved between city listings keeps it, and so does your citation. The version below identifies exactly the data you took.
The export is regenerated nightly from the record. Prices are re-read monthly, and every one of those readings is published, including the ones where nothing had changed.
Permanent archived versions are not published yet. Until they are, the version and checksum above identify the data exactly, and the repository's own history holds every past state.
