Actors are a software tools running on the Apify platform, for all kinds of web data extraction and automation use cases. In Batch mode, an Actor accepts a well-defined JSON input, performs an action which can take anything from a few seconds to a few hours, and optionally produces a well-defined JSON output, datasets with results, or files in key-value store. In Standby mode, an Actor provides a web server which can be used as a website, API, or an MCP server. Actors are written with capital "A". ## How to integrate an Actor? If asked about integration, you help developers integrate Actors into their projects. You adapt to their stack and deliver integrations that are safe, well-documented, and production-ready. The best way to integrate Actors is as follows. In JavaScript/TypeScript projects, use official [JavaScript/TypeScript client](https://docs.apify.com/api/client/js.md): ```bash npm install apify-client ``` In Python projects, use official [Python client library](https://docs.apify.com/api/client/python.md): ```bash pip install apify-client ``` In shell scripts, use [Apify CLI](https://docs.apify.com/cli/docs.md): ````bash # MacOS / Linux curl -fsSL https://apify.com/install-cli.sh | bash # Windows irm https://apify.com/install-cli.ps1 | iex ```bash In AI frameworks, you might use the [Apify MCP server](https://docs.apify.com/platform/integrations/mcp.md). If your project is in a different language, use the [REST API](https://docs.apify.com/api/v2.md). For usage examples, see the [API](#api) section below. For more details, see Apify documentation as [Markdown index](https://docs.apify.com/llms.txt) and [Markdown full-text](https://docs.apify.com/llms-full.txt). # README ## 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?"** ### What you get per item ```json { "query": "Game Boy Micro", "valuation": { "marketplace": "ebay.es", "median": 218.69, "n": 183, "confidence": "high", "currency": "EUR" }, "deals": [ { "source": "vinted", "title": "Game Boy micro en perfecto estado", "price": 100, "url": "https://www.vinted.es/items/...", "economics": { "estBuyTotal": 108.7, "estResaleNet": 162.92, "resaleShipping": 27.34, "estProfit": 54.22, "estMarginPct": 49.65, "verdict": "deal" } } ], "meta": { "listingsScanned": 67, "candidatesAfterFilters": 13, "filteredOut": { "titleMismatch": 21, "accessory": 3, "junk": 2, "suspiciouslyCheap": 5 } } } ```` 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. ### Input | Field | Description | |---|---| | `query` | Item to watch, e.g. `"Game Boy Micro"` — use a canonical product name | | `country` | `ES` (default), `FR`, `DE`, `IT`, `UK` — sets Vinted domain, eBay site and proxy country | | `items` | Watchlist mode: up to 20 items per run with per-item overrides | | `sources` | `vinted`, `milanuncios`, `wallapop` (all by default) | | `marketplaceForComps` | eBay site for valuation (default `ebay.es`) | | `marginMinPct` | Minimum estimated profit margin to report a deal (default 25) | | `priceMax` | Ignore live listings above this price | | `minTitleMatch` | Title relevance threshold 0-1 (default 0.75) | | `priceSanityMinPct` | Listings below this % of median = different product (default 10) | | `economics` | Override fee/shipping assumptions | ### Use with AI agents (MCP) This Actor is exposed as a tool on the [Apify MCP Server](https://mcp.apify.com): ```json { "mcpServers": { "deal-scanner-es": { "url": "https://mcp.apify.com?tools=jdepablos/second-hand-deal-scanner-es", "headers": { "Authorization": "Bearer " } } } } ``` Pairs well with [eBay Sold Price Appraiser](https://apify.com/jdepablos/ebay-sold-price-appraiser) — same valuation engine, standalone appraisals. ### 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`. ### More data tools by this developer - [eBay Sold Price Appraiser — real market value from confirmed sales](https://apify.com/jdepablos/ebay-sold-price-appraiser) - [Spanish Company Feed (BORME) — daily registry acts as JSON](https://apify.com/jdepablos/borme-company-feed) - [Spain Public Auctions (BOE) — judicial auctions with market comparison](https://apify.com/jdepablos/spain-boe-auctions) - [Trademark Watch (TMview) — new filings & opposition deadlines](https://apify.com/jdepablos/trademark-watch-tmview) # Actor input Schema ## `query` (type: `string`): Item you want deals for, e.g. 'Game Boy Micro'. Use a canonical product name — it drives both the source search and the eBay valuation. For multiple items use 'items'. ## `items` (type: `array`): Up to 20 items per run. Each entry: {"query": "..."} plus any per-item overrides (priceMax, marginMinPct, sources, ...). ## `country` (type: `string`): Market to scan. Determines the Vinted domain, the default eBay site for valuation and the proxy country. Wallapop & Milanuncios are Spain-only and are skipped elsewhere. ## `sources` (type: `array`): Marketplaces to scan for live listings. Non-Spanish countries support Vinted only (others are skipped). ## `marketplaceForComps` (type: `string`): Where resale value is computed from sold listings. Defaults to the eBay site of the selected country (keeps currencies consistent). ## `marginMinPct` (type: `integer`): Only report listings whose estimated profit margin (vs estimated buy total) reaches this percentage. ## `priceMax` (type: `integer`): Ignore live listings above this price (EUR). ## `condition` (type: `string`): Restrict the eBay sold comps used for valuation. ## `minTitleMatch` (type: `string`): 0-1: fraction of query words that must appear in a listing title (source search relevance is loose — this kills false positives). Default 0.75. ## `priceSanityMinPct` (type: `integer`): Listings priced below this % of the resale median are treated as a different product (accessory, single game, empty box), not a deal. Default 10. ## `maxListingsPerSource` (type: `integer`): How many live listings to pull from each source per item. ## `strictClean` (type: `boolean`): Drop lots/bundles/for-parts/repro listings on both sides (valuation comps AND live candidates). Recommended. ## `economics` (type: `object`): Optional cost model overrides: {"resaleFeePct": 13, "vintedBuyerFeePct": 5, "vintedShippingEst": 3.5, "milanunciosShippingEst": 0, "wallapopBuyerFeePct": 5, "wallapopShippingEst": 4}. ## `proxy` (type: `object`): Sources use DataDome — residential ES proxy is strongly recommended (default). ## Actor input object example ```json { "query": "Game Boy Micro", "country": "ES", "marginMinPct": 25, "condition": "any", "minTitleMatch": "0.75", "priceSanityMinPct": 10, "maxListingsPerSource": 40, "strictClean": true, "proxy": { "useApifyProxy": true, "apifyProxyGroups": [ "RESIDENTIAL" ], "apifyProxyCountry": "ES" } } ``` # API You can run this Actor programmatically using our API.
