We sell the hardware first. The software came second.
ING Listing Engine is built by Nick Squires at ING Mining LLC in Hanson, Massachusetts — an eBay seller since November 2009. Everything on this site is written from that account.
Most eBay software is written by software people who studied the problem. This one was written by the person with the pallet in the driveway. ING Mining buys, tests, repairs and resells ASIC mining hardware — plus industrial automation parts, telecom power gear, servers and graphics cards — and getting a few hundred tested machines onto eBay accurately turned out to be its own full-time problem. The app exists because that problem was ours before it was anyone else's.
That is the only real claim this site makes, so here is the evidence for it rather than an adjective.
The seller account, as eBay reports it
Read off ebay.com/str/ingmining on 29 July 2026. You can check every line of this yourself in about ten seconds, which is the point of putting it here:
| Seller | ingmining — ING Mining, United States |
|---|---|
| Member since | 30 November 2009 |
| Status | Top Rated Seller |
| Feedback | 100% positive |
| Items sold | 5.5K |
| Followers | 726 |
Two notes on that table, because the alternative is quietly rounding things up. The 5.5K is eBay's own rounding, not a precise figure — eBay displays it that way and we are not going to invent a decimal it does not publish. And ING Mining's own about page currently shows a follower counter reading 40,000+, which does not match what eBay reports; every figure in the table above is the one eBay itself showed on the date given, and where our own marketing and the source disagree, the source wins.
What is actually in the store
The store's own eBay categories are Computers/Tablets & Networking (components, enterprise servers, power protection), Business & Industrial (industrial automation & motion controls), and Coins & Paper Money (virtual currency — where ASIC miners live). Live listings on it as this page was written include:
- ASIC miners and their parts — Antminer S19 95TH and 110TH on VNish and Braiins firmware, S19k Pro 115TH, a Bitmain KS5 Pro Kaspa miner, S19 XP Pro and S19 Pro hashboards sold as tested-working and as AS-IS, APW12 power supplies, and a Lot of 20 — Antminer S19 110TH/s.
- Bench and repair tooling — universal Antminer test fixtures, hashboard testers with EEPROM editing, a BM1366 chip tester, APW12 PSU testers. The fixtures we sell are the fixtures we test on.
- Industrial automation — a Genuine OEM FANUC A05B-2301-C315 teach pendant, an Allen-Bradley PowerFlex 525 (25B-D6P0N104) and a PowerFlex 4M (22F-D2P5N103), both listed as tested.
- Telecom and datacentre — an Ericsson RBS 6000 baseband unit with radio modules, an Eltek LP DC power system with rectifiers and battery backup, a 24-port PoE+ managed switch, an NVIDIA Quadro P2000.
That mix is why the guides here lean towards heavy, technical, hard-to-price items. It is also the honest limit of what we know: we are not apparel sellers, and a page on this site will tell you so rather than pretend otherwise.
How the guides get written
Every guide on this site has to clear one bar before it ships: it must contain something you cannot get from any other page on the same search result — a number from our own sold-comp database, a real unedited screenshot of the app, or something that happened on this account.
The sold-comp database
We keep a local database of roughly 864,000 completed eBay sales, collected through 17 July 2026, because eBay's own public sold filter stops at 90 days. When a page here quotes a median, it is computed from that table and the query is printed so you can disagree with it. The demonstration that made the method worth trusting is on the AI listing guide: a 500-row pull for antminer s19 has a raw median of $69.00, which rises to $290.00 once accessories, hashboards and power supplies are stripped out — and 22 of those 500 "matches" were not Antminers at all, but mini-split air conditioners, earbuds, a robot-vacuum battery and a pair of Vans. A search for a Dell PowerEdge R740 returned 30,289 matches and not one actual server.
The app is pointed at our own account first
New features get run against this store before they get a page. The first Inventory Health scan covered 87 active listings with a median age of 199 days — and its first answer was wrong in a way worth publishing: it wanted $105 off each of 80 remaining units of a 138-day listing that had already sold 44 units and had 64 watchers. That is $8,400 of margin off a listing that was working. Fixing it moved the headline stale-capital figure on the same inventory from $260,218 to $185,664.
Screenshots are real or they are not used
Every screenshot on this site is captured from the running app and resized, never retouched, never mocked up. Where a screen is empty because there is no data behind it, it is captioned as an empty state instead of being filled with invented numbers. The capture tool never photographs the settings, licence or log screens, because those can render API keys.
What this site will not do
- No invented statistics. If a number is not reproducible from our data or checkable at a source we link, it does not go on the page.
- No fake reviews or testimonials. The feedback quoted anywhere on our properties is real eBay feedback from real buyers.
- No AI-generated images used as eBay listing photos, ever. Illustrations like the one at the top of this page are marketing art. Putting a generated image on a live listing is fabrication and it breaks eBay policy.
- Competitors get credited when they are better. Vendoo beats this product on five things outright — ten marketplaces to our zero, sale detection and auto-delist, iOS and Android apps against a Windows-only desktop, support seven days a week against one person, and a place in eBay's own third-party provider directory that we do not have. That is written down on our own product guide, not buried in a footnote.
- We publish faults in our own product. The app's default eBay final value fee was set to 13.25% when the real rate has been 13.6% since February 2025 — it flatters every pre-sale estimate by about $3.50 per $1,000. We published that instead of quietly patching it.
What the software costs, precisely
The app is free during the public beta. There is no card, no trial clock, and nothing behind a paywall. That is not a positioning statement — it is what the code does, and the code is public.
The beta licence key ING-BETA-2025 is compiled into the app and activates itself on install, so every feature is unlocked the moment it runs (LicenseService.cs). The server-side feature gate is a no-op — it returns nothing at all, under a comment reading "Freeware — no restrictions" (Program.cs). And if our licence server is unreachable, the app deliberately keeps working rather than locking you out of your own listings.
The honest caveats, in the order they will affect you:
- The AI is not free — it just isn't ours to charge for. You supply your own Anthropic Claude API key, and Anthropic bills that key directly at their rates. We add no markup and take no per-listing fee, but this is a real cost line and it is yours.
- eBay's API takes a few days to open. You need your own eBay developer account, and new accounts start sandbox-only. Production access is a support ticket that eBay typically turns around in one to three business days. Nothing we can speed up.
- Windows 10 or 11 only. No Mac build, no phone app, and the app targets eBay US. If you are on a Mac or you sell mainly on ebay.co.uk, this is not your tool today.
- It does not cross-list. It exports files for Facebook Marketplace, Amazon and Mercari; it posts to none of them, and it detects no sales on them, which means it cannot delist an item you have just sold somewhere else. If cross-listing is your bottleneck, pay Vendoo or List Perfectly.
- There is unused subscription code in the repository. It has never been switched on and cannot charge anyone: it needs a payment key that is not shipped in any build, and the endpoint refuses without one. We are not going to pretend it isn't there — you can read it — but no build that exists today can take your money.
- We have not decided what happens after the beta. No price has been set and none has been announced. Anyone telling you a free beta is guaranteed free forever is guessing; when there is a decision, it will be stated here and on the changelog before anything changes.
- The download lags the source. The installer on this site is version 2.3.1.0, built 24 July 2026. Features merged after that date — the cross-listing exporter among them — are in the code but not in the file you would download today. The changelog splits the two lists on purpose.
- It is one person. There is no support team and no seven-day phone line for the software. Bug reports go to GitHub issues, where they are tracked in public, or to the email below.
