Returns each vendor offer's daily price for one GPU model over an inclusive UTC date window, as step series built from every completed price scrape. A day's point is the offer's last price observed that day. Days with no change are still emitted, so a series can be drawn as steps: a day on which no scrape read the vendor carries its last price forward. A day is omitted while the offer is not listed (before the vendor first listed it, or after a scrape found it withdrawn), and days after the current UTC date are never emitted.

An offer is identified by its vendor-published fields, the same vocabulary as /v1/gpu-prices/current; no two offers in one response share all of them. The window spans at most 92 days (400 otherwise), and an empty window is an empty offers array.

Requires the gpu-prices entitlement family; requests without it return 404 not_found.
