This is the open, sourced dataset behind everything on the site — and the foundation for natural-language queries. Browse it below, filter by category and data tier, and see exactly where every number comes from.
The whole dataset is open and reproducible. Download it, or cite the headline figure like you would CPI.

✓ Verified = price web-checked against its source. ⏳ Pending = a best-known objective figure already tagged to its official source, awaiting per-item verification (only verified items feed the game and the headline index). We're verifying down the list Tier 1 first. Click a column header to sort.
Every figure runs through an automated audit: a statistical outlier check (does this item's implied inflation diverge sharply from comparable goods in its category?), basic sanity checks, real-data-overlay coverage, and — where available — an independent second source for the current price. The dot reflects the result. This is the opposite of a black box: the rule is open (scripts/verify.js) and every flag is shown on hover.
