AuctionSignalBot

AuctionSignalBot collects publicly available auction listing facts — lot titles, closing dates, current bids, locations and specifications — so that professional equipment buyers can find relevant lots without opening forty tabs every Monday morning.

What we do

• Honor robots.txt and Crawl-delay on every request.
• Honor 429 and Retry-After by permanently lowering our rate for that site.
• Use conditional requests (ETag / If-Modified-Since) so most visits transfer nothing.
• Identify ourselves consistently. We never rotate identities or disguise the crawler.
• Display factual metadata, a short excerpt, a permitted thumbnail, and a prominent link back to your listing.

What we never do

• Attempt logins, CAPTCHAs, paywalls, or geo-restrictions. Sites behind those are recorded as unsupported in our public coverage ledger.
• Bid on any lot, on anyone's behalf, ever.
• Republish complete descriptions, full galleries, or documents without permission.

Send us a feed instead

If you would rather send us a feed than be crawled, we would rather have the feed. It is faster, more accurate, and you control what we show. See the open AuctionFeed schema — it is free to implement.

Opt out

Email bot@auctionsignal.app from an address at your domain. We stop crawling within one business day, permanently, and your domain shows as opted out in the public ledger. If you would rather do it yourself, POST {"domain":"example.com","email":"you@example.com"} to /api/public/opt-out.
