Bring a Trailer Auctions Scraper

🚀 Bring a Trailer Auctions Scraper

Easily extract completed auction results from Bring a Trailer (BaT). The Bring a Trailer Auctions Scraper collects sale prices, high bids, auction outcomes, end dates and vehicle specs for any make or model, which is useful for collector-car comps, dealer pricing and market research.

✨ Features

• 🏁 Auction outcomes, not just prices: every result is labelled as sold at auction, sold after the auction, reserve not met or withdrawn, with the sale price and the high bid kept in separate fields.
• 🔍 Keyword search: search completed auctions by keyword (porsche 911, bmw m3, ford bronco) and filter for sold or unsold results only.
• 📅 Date range: limit results to auctions that ended between two dates. This is useful for weekly or monthly comps.
• 🚗 Vehicle specs: turn on details to add the bid count, lot number, make, model, era, category, mileage, listing details (engine, gearbox, colors, options), seller type (dealer or private party) and main photo.
• 🧩 Parts flagged: parts and memorabilia lots (manuals, wheels, signs) are marked isVehicle: false, so they don't skew your car comps.
• 🔗 Direct auction URLs: paste individual auction pages to get their full results.
• 📋 Run summary: every run saves a summary that shows how many auctions matched and why the run stopped. It also shows whether a search reached the site's result limit.

🛠️ How It Works

1. Enter keywords or auction URLs, for example porsche 911 or https://bringatrailer.com/listing/2017-porsche-911-carrera-coupe-40/.
2. Pick filters (optional): sold or unsold only, an end-date range, and whether to scrape full auction details.
3. Run the scraper: results come back newest first as structured JSON, CSV or Excel.

Good to know

• Sold after auction: a car can sell after the auction ends. When it does, the final bid and the sale price differ, e.g. a bid of $91,500 and a sale of $99,000. With details on, you get both numbers and the correct outcome. Without details, the outcome is sold and both amounts come from the search results.
• Reserve not met means the high bid did not meet the seller's reserve. soldPrice is empty and highBid holds the last bid.
• Amounts are auction results as reported by Bring a Trailer. They do not include the buyer's fee, taxes or shipping.
• Search limit: Bring a Trailer shows about 10,000 results per search. When a search is larger, the run summary says truncated: true. Use a narrower keyword or a date range to reach older auctions.
• Mileage is kept exactly as listed ("68k Miles Shown", "42k Miles Shown, TMU").

💰 Pricing

Event	Price
Auction result (from search)	$0.001
Auction result with details	$0.005

If the details for an auction can't be loaded, you still get the search result, charged as a plain auction result.
