I Let an AI Agent Browse Auction Sites While I Slept — Here's What It Found
One thing I hear a lot: "How do you keep up with all the auction sites without spending hours every day?"
Here's exactly what I've been running this week.
I set up an AI agent that browses Troostwijk, Surplex, Klaravik, and NetBid every morning, filters for my core brands and product types, scores each lot, and sends me a ranked report before I've had my first coffee.
This is what yesterday's report looked like:
The top find: a 430-lot industrial electrical auction in Zonhoven, Belgium (Troostwijk A1-43714). One company's entire inventory going under the hammer — 60 Siemens lots, 62 ABB lots, 14 Schneider lots, plus sensors, contactors, relays, and cables. Lots starting from €50. The agent flagged this as 10/10 and it closes Friday. I would have missed this entirely if I was browsing manually.
Other standouts from the same report:
- 50x Siemens SIMATIC ET200 I/O modules (Surplex, Netherlands) — starting price €10. Zero bids at time of scan. These sell for €15–40 each on eBay.
- 2 lots of 5x Danfoss VLT FC-302 frequency converters (Surplex, Netherlands) — €100 start per lot, no bids. FC-302s go for €150–400+ each depending on spec.
- Siemens S7 CPU + I/O modules lot (Surplex, Germany) — €100 start, complete set including power supply. CPU alone sells for €200–500+ on eBay.
- Batch of Siemens + Allen-Bradley PLC modules (Troostwijk, Belgium) — already 12 bids at €210. Demand confirmed.
The agent also found a Danish pallet box of electrical components on Klaravik in Vejen — 0 DKK start, no reserve, Danish pickup. Low risk, low cost.
10 ranked lots. Total browsing time for me: 4 minutes.
The scoring logic is built around my actual inventory — Siemens, Omron, SICK, ABB, Danfoss, Allen-Bradley, Festo — and prioritizes bulk lots over single items. Every lot in the report includes current bid, closing time, location, and a direct link.
This isn't theory. That Troostwijk Belgium auction is real, it closes in two days, and I'd never have found it without the agent running overnight.
If you're selling industrial automation on eBay and you're still manually browsing auction sites — you're leaving deals on the table.
