Bring a Trailer Vehicle Auction Comps

Analyze recent completed vehicle auctions for exact Bring a Trailer model pages. Get sold-price quartiles, separately counted unsuccessful auctions, and auditable comparable links for acquisition and pricing decisions.

Price: $0.05 per successful model report (vehicle-model-analyzed).

Input

Provide modelUrls with 1–5 public HTTPS model URLs, such as https://bringatrailer.com/acura/legend/. Search, listing, member, account and query URLs are not accepted. lookbackDays defaults to 365; currency defaults to USD. Optional yearMin and yearMax narrow vehicle years. maxComps defaults to 20 evidence links per report; maxItems caps model reports at 5. Duplicate model URLs are analyzed once.

Output

One row per successfully analyzed model: modelUrl, modelName, currency, status, soldCount, unsoldCount, excludedCount, priceSummary (median, p25, p75, minimum, maximum), comparables, coverage, filters, reason, and fetchedAt. Comparable fields are auction ID, source URL, vehicle year, sold date, amount and currency. Quartiles use linear interpolation at (n-1)*p. Statistics include all qualifying chart records in the selected period, not merely the returned evidence links.

Parts-only auctions, unclear vehicle identities and other currencies are excluded. Unsuccessful high bids are never counted as sold prices. Fewer than three qualifying sales returns insufficient_comps with null quartiles and median; min/max remain available for one or two sales. Zero qualifying sales returns no_matching_sales and null price statistics with an explanation. Sold prices are displayed auction outcomes and exclude buyer fees, taxes, shipping and verified settlement. The model category may mix trims and conditions; no mileage or condition adjustment is claimed. Coverage describes only records available in the source chart, not the entire vehicle market. No market-wide sell-through estimate is produced.

Pricing

$0.05 per successful model report, charged once as vehicle-model-analyzed. A valid report explaining no matching sales is a successful analysis and is billable. Comparable links and unsuccessful-auction counts add no charge. Retrieval, parsing and authentication failures produce no billable report. The example input requests one model report and uses the same event against any available Apify credit; it does not promise a zero-dollar run or apply a customer-plan restriction. maxItems and the available event budget limit fetched and emitted reports before work begins. A later source failure does not undo earlier completed reports or their charges.

Limits

At most five model-page requests, no retries, concurrency one, at least two seconds between requests, 8 MB maximum response and 180 seconds per run, using 256 MB memory without a browser or paid external API. A 401/403/challenge is an access failure, 429 is a rate-limit failure, timeouts fail explicitly, and missing or inconsistent chart structure is a parser error. A zero result is valid only after the source structure and model identity were verified. Runtime requests are limited to prechecked model paths; robots are rechecked in the release process. Source URLs are restricted to the exact permitted host and redirects are not automatically followed.

Privacy

No seller or bidder identities, addresses, VINs, coordinates, comments, listing descriptions, images or raw auction titles are output or persisted. Source titles are examined transiently only to recognize vehicles and filter parts. Output is an allowlist of factual auction values and source links.
