This page explains what the tables measure, where the inputs come from, what is missing, and how to request a correction.
Published prices, calculated comparisons, and active probes are kept separate. A missing field stays missing; it is not turned into a score.
Price order answers a price question only. It is not a guarantee of model authenticity, uptime, billing accuracy, or support quality.
Official API prices use vendor-published USD prices without currency conversion. Relay prices use publicly reachable model and group data. The comparable value is model_ratio × group_ratio × $2/M; expression-based billing is excluded instead of guessed.
Subscription listings come from publicly reachable shop pages. Terms are normalized to 30 days when the duration is readable. Deposits and balance-payment listings are excluded because the sticker price is not the full product price.
Coverage includes only sources that can be collected and mapped to a known site, model, group, or subscription form. It is not a claim to cover the whole market.
The relevant pages show site count, quote count, probe coverage, and unreachable shops. A source that cannot be reached is reported as missing, not silently treated as zero.
Each published snapshot carries collection timestamps. Pages display the oldest relevant successful collection time so the reader can judge the age of the visible data.
A briefly cached page does not make an old source fresh. The source timestamp shown with the data is the freshness signal.
Quality probes are reported separately from price collection. If probe coverage is zero, the site says so and does not invent a quality score.
The online checker uses the temporary test key supplied for that run. The key is not persisted or logged and should be a disposable key.
