Second-hand Deal Scanner EU — Vinted, Wallapop & Milanuncios vs Real eBay Sold Prices

One call = one item watched. Give it any item ("Game Boy Micro") and a country (Spain, France, Germany, Italy or the UK): it scans live Vinted listings (plus Wallapop & Milanuncios in Spain), values the item from confirmed eBay sold prices on the local eBay site, and returns only the listings you can actually profit from — ranked by estimated net profit.

Most marketplace scrapers dump every listing on you. This Actor answers the question resellers actually have: "Which of these is a real deal, and how much would I make?"

Real example above: 40 live listings scanned, 3 genuine deals found — a working console at €100 versus a €218.69 median of 183 confirmed sales.

Why the deals are trustworthy

• Valued against SOLD prices, not asking prices — the resale value comes from confirmed eBay sales (median of up to 240 recent comps, cleaned of lots/for-parts/repro junk).
• False-positive killers built in: listings for a different product in the same family ("FIFA 2006 for GBA" when you watch a Game Boy Micro), accessories ("stand for...", "case for..."), and too-cheap-to-be-true mismatches (below 10% of median) are filtered out — each rejection is counted in meta.filteredOut so you can audit it.
• Honest economics: buy side includes Vinted buyer protection (~5% + €0.70) and shipping; sell side deducts marketplace fees (~13%) and real median shipping from the comps. All rates are overridable.
• Per-source resilience: if one source blocks or changes, you still get deals from the others, with the failure documented in meta.sourceErrors.

Use cases

• Resellers / flippers: watch your 20 best-known items, run daily, buy only what clears your margin threshold.
• AI agents: one tool call = ranked arbitrage opportunities with the math already done.
• Collectors: get alerted when your grail shows up underpriced on Spanish second-hand markets.

Pricing

Pay per event: one flat fee per watched item scanned — all sources, valuation and deal math included. Failed items are never charged.

FAQ

Why did my scan return 0 deals? That's the product working: most live listings are fairly priced. Lower marginMinPct to see borderline candidates, and check meta.filteredOut to see what was rejected and why.

Are the profit numbers guaranteed? They're estimates: median resale minus realistic fees and shipping. Condition, completeness (box/charger) and negotiation move the final number. The comps and their URLs are in the valuation so you can verify before buying.

Does it work outside Spain? Yes — set country to FR, DE, IT or UK to scan the local Vinted against the local eBay sold prices. Wallapop and Milanuncios are Spain-only extras. Cross-country arbitrage (buy FR, sell DE) works by combining country with an explicit marketplaceForComps.
