eBay Sold History & Sales Spy – velocity, daily revenue and price trends on any eBay listing

eBay quietly removed the public “View sales history” link in 2023 – but the data is still there. This extension by Chedgzoy adds a one-click “Sold Spy” tab to every eBay listing and overlays a clean panel showing total sold, daily revenue, 7- and 30-day velocity, top variation and price trend – everything a reseller, dropshipper or buyer actually needs to see.

Add to Chrome Coming soon Or use the web tool – no install needed.

Everything you need to research a listing in one click

Calculated locally in your browser from eBay’s own data. No third-party servers, no Chedgzoy account, no tracking.

Daily revenue

Quantity sold and gross revenue for every day in the listing’s history. Spot hot days, slow days and seasonal patterns at a glance.

Sales velocity

Last 7 days and last 30 days – sales count, revenue and per-day average. Know how fast something actually moves before you stock it.

Price trend

Rising, falling or stable – calculated from the oldest 25% of sales vs the newest 25%. See if the market is moving for or against you.

Price range

Lowest and highest realised sale prices with the average. Price your own listing competitively without guesswork.

Top variation

For multi-variation listings, the size, colour or option that’s actually selling. Find the winning SKU before you commit stock.

UK & US support

Detects ebay.co.uk and ebay.com automatically and switches currency. The web tool here works for any eBay country domain.

How it works

  1. Browse any eBay listing as you normally would. The extension adds a small “Sold Spy” tab to the right edge of the page.
  2. Click the tab. eBay’s own legacy sold-history page opens in a new tab. If you are not already signed in to eBay, it will prompt you.
  3. Read the panel. A slide-in panel summarises total sold, revenue, average price, 7- and 30-day velocity, the top variation, the price trend and a daily breakdown.

About the eBay Sold History & Sales Spy extension

eBay Sold History & Sales Spy is a free Chrome and Edge browser extension by Chedgzoy. It adds a small “Sold Spy” tab to every eBay listing and, with a single click, opens a slide-in panel that summarises the full sold-item history of that listing – total sold, total revenue, average price, recent velocity, top variation and a price trend indicator. All the maths runs locally in your browser, and nothing is sent to a third-party server. You do need to be signed in to eBay for the underlying sold-history page to load, the same as for any logged-in eBay feature.

What is the eBay sold items history?

Every eBay listing quietly builds up a record of every time it sells – date, price, quantity and a masked buyer username. This record is what sellers and buyers call the sold items history or sale history, and it’s the single most useful dataset on eBay for understanding what something actually trades for.

Until early 2023, eBay displayed a “View sales history” link on every item page and anyone could click through and browse the data. In March 2023, eBay removed that link from public view. The data itself still exists – eBay’s own systems use it internally – and the endpoint that serves it is still reachable. The extension and the web tool above just construct the correct URL so you can see it again.

No data passes through this website. The web tool builds an eBay URL for the item you enter and sends you straight to eBay. The extension reads the table that eBay has already loaded into your browser and computes the statistics locally. Nothing about your queries is logged on this site.

What sales metrics does the extension calculate?

  • Total sold and total revenue across the entire history of the listing.
  • Average sale price – useful when prices shift across best-offer accepted sales.
  • Lowest and highest sale price in the visible history.
  • Sales velocity – sales count and revenue for the last 7 days and last 30 days, with implied per-day rates.
  • Top variation – the size, colour or option that has sold most.
  • Daily breakdown – quantity and revenue for every day with at least one sale, newest first.
  • Trend indicator – Rising, Falling or Stable based on the oldest 25% of sales versus the newest 25%, with a 5% threshold to avoid noise.

Why check eBay price history?

Seeing what an item has actually sold for – not what sellers are currently asking – is the most reliable way to gauge its real value. A few of the more common reasons people look up eBay sold history:

  • Reselling. Before listing something, check what identical items have sold for in the last few months. This tells you what to price yours at, and whether it’s even worth listing.
  • Buying smart. Before accepting a “Buy It Now” price, check the history. If recent sales are 30% lower, you’re about to overpay.
  • Collectibles and vintage. Rare items can fluctuate wildly. Sold history shows real market values rather than wishful-thinking asking prices.
  • Sourcing decisions. If you’re picking up stock to resell, sold history tells you which items move and which sit. Volume matters more than one lucky sale.
  • Seller research. For multi-quantity listings, sold history reveals whether a seller genuinely moves a lot of stock or is a low-volume hobbyist.
  • Spotting trends. Prices clustered around a recent date may signal new interest (a viral mention, a film release, a reissued model). Older-only sales may signal a product that’s fading.

How to find an eBay item number

The item number (also called the item ID) is the 12-digit number at the end of every eBay listing URL. It uniquely identifies the listing.

  • On a full URL: look for the segment after /itm/. Example: https://www.ebay.co.uk/itm/143153698452?var=642512036099 – the item number is 143153698452, everything before or after can be ignored.
  • On a shared short URL: open it once in a browser; eBay will redirect to the full URL and you can copy the item number from there.
  • From the listing page: scroll to the bottom; the item number is printed underneath the listing description.

Frequently asked questions

Who makes the eBay Sold History & Sales Spy extension?
It’s built and maintained by Chris Chedgzoy, the same author as the rest of the free tools on this site. Published under the “Chedgzoy” publisher name on the Chrome Web Store.
Is the extension free?
Yes. Free to install, free to use, no premium tier, no ads, no subscriptions. If it saves you time and you’d like to support it, there’s a Buy Me a Coffee link in the footer.
Does the extension send any of my data to a server?
No. It reads the sales table that eBay loads into your browser once you are signed in, and calculates the statistics locally. There are no analytics, no remote API calls and no Chedgzoy account. The full privacy policy is here.
How far back does the eBay sold items history go?
eBay’s sold history endpoint typically returns every recorded sale while the listing remains active, and for a period after it ends. Multi-quantity “always on” listings can therefore show months or years of sales. eBay doesn’t publicly commit to a retention period, so the exact amount varies per listing.
Does this work for ended listings?
Yes, as long as eBay still has the history for that item number. Very old listings can return empty results or redirect to the main item page.
Why isn’t eBay’s sold history shown on the item page any more?
eBay removed the public “View sales history” link from item pages in March 2023. The stated reason at the time was a broader refresh of the buyer interface. The underlying data and endpoint still exist.
Do I need an eBay account to use this?
Yes. eBay’s purchase history page requires you to be signed in to your eBay account before it will show the sales. This tool just builds the correct link for the item you enter; you’ll be prompted to sign in (or it will load straight away if you’re already signed in) when the page opens.
Is it legal to check eBay sold history this way?
Yes. Neither the extension nor the web tool scrapes, bypasses a login or accesses private data. They both link to eBay’s own sold-history page using the item number you provide, and eBay then asks you to sign in (if you are not already) and serves the data directly to your browser.
The page I get from eBay is empty. What does that mean?
An empty sold-history page usually means the listing has had no recorded sales yet, or the item number is for a listing that’s very new, very old, or has been restricted by eBay. Double-check the item number and try again.
Will eBay break this in future?
It’s possible. The legacy sold-history endpoint has been around for many years but eBay can change anything at any time. If they remove or restrict it, both the extension and the web tool would stop working until I find another route.
