API

Every page on this site is also JSON: same path, /api in front. No key. CORS is open. Responses are cached at the edge for an hour, so cache on your side too.

Endpoints

GET /api/index
    Every handgun, handgun+light pair and maker with live fit data, plus totals.
    Use it to discover slugs.

GET /api/holsters-for/{firearm}
GET /api/holsters-for/{firearm}/with/{light}
GET /api/holsters-for/{firearm}/no-light
    Holsters for that handgun. Each holster carries its fits (one per light),
    the grade, the maker's quoted text, the source URL and the date last seen.

GET /api/makers/{maker}
    One maker: the handguns it covers and its holsters with stated fits.

Grades

confirmed: the maker names the exact model (and exact light, when one was requested).
probable: the maker lists it with wording the matcher scored under 0.9. Show the quote.
likely: matched through the base model or base light.

If you show this data to people, show the grade and the quote with it. That is the whole point.
