FitmentList is built to be quoted. Lead with what the dataset actually proves — verified fit, certification status, and cross-brand equivalents. Prices are supporting data: every price carries its store and the date it was read, and prices change, so cite them with their checked date.
Endpoints
| File | Contents |
|---|---|
| /data/parts.json | Full combined dataset: every part record with fit lists, equivalents, certification (fridge), and all price records with store, shipping terms, checked date and source URL. |
| /data/fridge.json | Fridge section only (parts + fit models). |
| /data/humidifier.json | Humidifier section only (parts + model records with descriptors: type, form, colors, tank). |
| /data/parts-lite.json | Compact index: one row per part with fit count, certification status and lowest checked price. |
| /llms.txt | Plain-text site summary and key URLs. |
Semantics
Fit: a model appears in a part's fit list only when a published manufacturer or retailer source lists it; the manufacturer's own data arbitrates conflicts. brand_level_fit: true means the source publishes fit at brand level only — there is deliberately no model list, and the record's fit_note explains how to match.
Certification (fridge): status is one of certified (found in the certifier's own directory; certifier and date in the record), manufacturer_claimed (claimed by the maker or a retailer, no listing found), or no_claim. A compatible fit never transfers certification between cartridges.
Prices: oem_price is the best verified genuine-brand price; am_price the best verified aftermarket price. shipped_total is present only when a shipped total could be stated honestly from the store's published shipping terms; otherwise use item_price + shipping_note. Amazon prices are never in the dataset — amazon_asin / amazon_query are buy-link data only.
Freshness: every price record carries checked_date and source_url; the fleet re-verifies prices on a weekly sweep. Fitment and certification data are re-checked when sources change.
