# eBay — Sold Listings Search

> Keyword + filters → paginated list of items that actually sold on eBay, with final price, sold date, condition, listing format, shipping, seller, and images.

## Language

All process output to user (progress updates, process notifications) follows the user's language.

## Objective

Given one or more search keywords, fetch real sold (completed) listings from a chosen eBay marketplace with a user-defined filter set (category, price range, item condition, item location, sort order, completed-listings toggle), paginate up to the desired result count per keyword, and return one structured record per confirmed sale.

## Prerequisites

- Target eBay marketplace search page reachable in the browser: e.g. `https://www.ebay.com/sch/i.html?_nkw={keyword}&LH_Sold=1`. No login required.
- Ability to run `python`, `browser-act`, and `bash` (for `eval "$(python ...)"`).

## Pre-execution Checks

### 1. Tool Readiness

If browser-act has been confirmed available in the current session → skip this step.

Invoke `browser-act` via Skill tool to load usage. If installation or configuration issues arise, follow its guidance to resolve then retry.

## Capability Components

> This Skill's operational boundary = what the user can manually do in their browser. It only reads data already displayed to the user on the search results page, never bypassing authentication or access controls. Its role is equivalent to copy-pasting on the user's behalf — the sold data is already on screen, automation merely saves time. JS code is encapsulated in Python files under the `scripts/` directory, invoked via `eval "$(python scripts/xxx.py {params})"`. `$(...)` is bash syntax; use the bash tool for execution.

Below are all atomic capabilities discovered and verified during exploration. Combine freely as needed.

### URL Builder: assemble a sold-listings search URL for any of the 8 marketplaces

`URL=$(python scripts/build-url.py '{keyword}' --ebaySite {ebaySite} --sortOrder {sortOrder} --categoryId {categoryId} --subcategoryId {subcategoryId} --itemLocation {itemLocation} --itemCondition {itemCondition} --minPrice {minPrice} --maxPrice {maxPrice} --includeCompletedListings {true|false} --ipg {60|120|240} --page {pageNumber})`

The script prints one URL to stdout — capture into a bash variable and pass to `navigate`.

Parameters:
- `{keyword}` (positional, required): search term. 1–6 terms should each be run through a separate call.
- `--ebaySite`: `ebay.com` (default) · `ebay.co.uk` · `ebay.de` · `ebay.fr` · `ebay.it` · `ebay.es` · `ebay.ca` · `ebay.com.au`
- `--sortOrder`: `endedRecently` (default, `_sop=13`) · `timeNewlyListed` (`_sop=10`) · `pricePlusPostageLowest` (`_sop=15`) · `pricePlusPostageHighest` (`_sop=16`) · `distanceNearest` (`_sop=7`)
- `--categoryId`: main category filter (`_sacat`); default `0` (All Categories). Common IDs: see "Enum Parameters" section.
- `--subcategoryId`: subcategory ID; when set, overrides `--categoryId`.
- `--itemLocation`: `default` (`LH_PrefLoc=98`) · `domestic` (`LH_PrefLoc=1`, US Only on ebay.com) · `worldwide` (`LH_PrefLoc=2`)
- `--itemCondition`: `any` (no filter) · `new` (`LH_ItemCondition=1000`) · `used` (`LH_ItemCondition=3000`) · or pass any numeric eBay condition id (e.g. `1500` for Open Box, `2010` for Excellent Refurbished, `7000` for Parts). See enum section.
- `--minPrice` / `--maxPrice`: numeric filters `_udlo` / `_udhi`.
- `--includeCompletedListings`: `true` (default, adds `LH_Complete=1` — Best-Offer-Accepted detection works) or `false` (BOA appears as plain `buy_it_now`).
- `--ipg`: items per page — `60` (default), `120`, or `240`. Larger `ipg` fetches more per page but pages get heavier.
- `--page`: page number for pagination (`_pgn`), default `1`.

Output: a single fully-qualified URL string on stdout.

### DOM: extract sold-listing cards from the current eBay search results page

Prerequisite: browser is currently on an eBay sold-listings search URL and the results have rendered.

1. `navigate "$URL"` (using URL from build-url.py)
2. `wait --selector "li.s-card" --state visible --timeout 30000` (eBay may show a splash challenge before the results page; the splash resolves itself and `li.s-card` appears)
3. `eval "$(python scripts/extract-page.py --keyword '{keyword}')"`

Parameters of `extract-page.py`:
- `--keyword`: pass-through tag written to each item's `keyword` field so multi-keyword batches can be regrouped later. Optional; empty by default.

The extractor filters out eBay's promotional "Shop on eBay" placeholder cards automatically, only keeping cards with a real `data-listingid`.

Output example (top-level shape):
```json
{
  "error": false,
  "pageUrl": "https://www.ebay.com/sch/i.html?_nkw=iphone+15&LH_Sold=1&LH_Complete=1&_ipg=60&_pgn=1&_sop=13",
  "heading": "17,000+ results for iphone 15",   // total count string as shown on the page; may say "10,000+" for very large sets
  "categoryId": null,                            // _sacat from URL, null if All Categories
  "category": "Cell Phones & Smartphones",       // label from the eBay category dropdown
  "itemCount": 60,                               // number of real items (excludes promo cards)
  "hasNextPage": true,                           // whether a "Next" pagination link exists
  "nextUrl": "https://www.ebay.com/sch/...&_pgn=2", // href of the Next link, if present
  "items": [ /* array of item records */ ]
}
```

Per-item record example:
```json
{
  "itemId": "198484429340",                                   // eBay item ID
  "url": "https://www.ebay.com/itm/198484429340",             // canonical item URL (query stripped)
  "title": "Apple iPhone 15 Pro 128GB Blue A2848 Triple ...", // localized card title
  "condition": "Pre-Owned",                                    // localized condition label as displayed (Pre-Owned, Gebraucht, Neuf, Nuovo, Usado, Open Box, etc.); null when not shown
  "conditionId": 3000,                                         // best
