Marketplace coverage varies by country. Australia currently has the widest live marketplace coverage, with additional markets being added progressively.
Trust through transparency
Clear inputs, visible assumptions and conservative labels—without invented sales data or promises of profit.
Each market uses its own eBay listings and currency. Australia also has fully modelled local selling fees.
Live eBay active listings come through the official eBay Browse API. Asking prices are never presented as sold prices.
See how fees, postage and costs shape estimated profit, ROI, downside and the maximum price to pay.
Identity checks separate the target product from compatible accessories, parts, empty boxes and unrelated listings before valuation.
Your saved deals, photos and settings are protected by account-level data controls.
How it works
Add the item title, condition, purchase price, where you found it, intended selling platform and an optional photo.
Valnexi checks relevant live eBay asking prices in your market, filters mismatched products and applies the selling channel's fees and costs.
See estimated resale, profit, ROI, risk, maximum buy price and Deal Score, with confidence and assumptions made clear.
