How this endpoint behaves

Returns the price chart Bring a Trailer draws for a make or a model: how much its completed auctions sold for, over time. It is a different view from bringatrailer-results, which pages through individual auctions.

Exactly one of make and model_id is required (Bring a Trailer only draws the chart for one of them). make is a make name from bringatrailer-makes and model_id a numeric models[].model_id from the same endpoint. The other filters of bringatrailer-results narrow the chart: q, exclude, category, era, origin, country, type, recency, min_year, max_year and max_bid (see bringatrailer-filters for the values). result and sort are not accepted: the chart always returns both the sold and the reserve-not-met series so the two can be compared.

type is premium or noreserve. recency is the closing window: 7D, 30D, 1Y, 2Y or 5Y (omit for all time).

points_limit is how many of the most recent auctions to list in points, 0 to 1000 (default 100). 0 returns only the summaries and the yearly table.

Notable response behavior:

• sold and reserve_not_met each give count, min, median, mean and max of the final bids in USD (for a reserve-not-met auction the final bid is the high bid that failed to meet the reserve). All figures are computed over every auction in the chart, not just the listed points.
• sold_by_year is the same summary for sold auctions grouped by closing year, newest year first.
• points are the most recent auctions, newest first, each with id, title, url, amount, date (RFC 3339 UTC) and status (sold or reserve_not_met). Pass url to bringatrailer-listing for detail.
• Bring a Trailer returns at most the most recent 10,000 auctions. When a filter matches more, truncated is true, the summaries cover only the window between window_start and window_end, and a narrower filter (a model, a recency or a year range) returns the whole history. Porsche, for example, is truncated.
• A filter that matches no auctions returns zero counts and empty lists, not an error. An invalid country returns 400.
• Large makes are computed on demand upstream and can take up to about 50 seconds, and the upstream body is 2 to 4.5 MB. A model is typically fast. The route allows 55 seconds.
