Primary Arms API and integration
Primary Arms syncs the smallest catalog Project Parabellum connects to, over a dealer API, and at that size the pass itself is a rounding error against the wait between passes: nearly all of the age showing on the sync clock is time spent waiting for the next scheduled poll rather than time spent working through rows. Practically, that means a figure on this page is either current or one interval old, with very little in between. A half-synced, still-in-flight state barely exists on a feed this narrow.
What Project Parabellum normalizes from Primary Arms
Project Parabellum normalizes every item in the Primary Arms feed — manufacturer, model, caliber, and category — into a shared vocabulary, so the same UPC carried by Primary Arms can be compared against the same UPC carried by any other distributor we sync, rather than compared only within Primary Arms's own naming. Dealers who connect their own Primary Arms credentials see account-specific availability on top of that; everyone else sees catalog breadth and stock presence.
