E-commerce — Product Listing

Category/search URL or keyword + filters → paginated product list (URL, name, price, image, rating per item)

Language

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

Objective

Extract a structured list of products from any e-commerce category, search results, or keyword search page, with support for price/brand/rating filters and multi-page pagination.

Prerequisites

  • Target browser is open and connected
  • No login required for public listing pages

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 page. JS code is encapsulated in Python files under the scripts/ directory, invoked via eval "$(python scripts/xxx.py {params})". Use the bash tool for execution.

DOM: Extract product list from current page

Navigate to the listing/search page first, then extract:

eval "$(python scripts/extract-listing.py --max-results 20)"

Parameters:

  • --max-results: max items to return per page, default 20

Output example:

{
  "count": 20,
  "items": [
    {
      "url": "https://www.amazon.com/dp/B09WNK39JN",
      "name": "Amazon Echo Pop",
      "price": 39.99,
      "currency": "USD",
      "image": "https://m.media-amazon.com/images/I/...jpg",
      "rating": 4.7,
      "review_count": 103789,
      "asin": "B09WNK39JN"
    }
  ]
}

DOM: Get next page URL

After extracting a page, get the URL to navigate to for the next page:

eval "$(python scripts/extract-listing-next-page.py)"

Output example:

{"next_url": "https://www.amazon.com/s?k=headphones&page=2", "has_next": true, "method": "amazon"}

When has_next is false, pagination is complete.

Composite: Keyword search with filters → product list

Step 1 — Build search URL with filters:

Construct the URL based on target site and desired filters using the patterns below, then navigate:

Amazon (amazon.com):

https://www.amazon.com/s?k={keyword_urlencoded}&s={sort}&rh={filter_params}
  • Sort (s): price-asc-rank | price-desc-rank | review-rank | date-desc-rank (omit for relevance)
  • Price filter: append p36:{mincents}-{maxcents} to rh (dollars × 100, e.g. $50–$200 → p36:5000-20000)
  • Rating filter: append avgcustomerreview:four-and-above | three-and-above | two-and-above to rh
  • In-stock: append pnavailability:1248801011 to rh
  • Multiple rh values: comma-separate (e.g. rh=p36:5000-20000,avgcustomer_review:four-and-above)

eBay (ebay.com):

https://www.ebay.com/sch/i.html?_nkw={keyword_urlencoded}&_udlo={min_price}&_udhi={max_price}&_sop={sort_num}
  • Sort: 12=BestMatch | 15=PriceLow | 16=PriceHigh | 24=NewlyListed

Walmart (walmart.com):

https://www.walmart.com/search?q={keyword_urlencoded}&min_price={min}&max_price={max}&sort={sort}
  • Sort: bestmatch | pricelow | pricehigh | ratinghigh

Google Shopping (cross-site, no --site):

https://www.google.com/search?tbm=shop&q={keyword_urlencoded}&tbs=p_ord:{sort}
  • Sort: rv=relevance | pd=price ascending | prd=price descending

Any site with --site (generic):

https://{site}/search?q={keyword_urlencoded}

Step 2 — Navigate and extract:

  1. navigate {constructed_url} → wait stable
  2. eval "$(python scripts/extract-listing.py --max-results {n})"

Step 3 — Paginate (repeat until done):

  1. eval "$(python scripts/extract-listing-next-page.py)"
  2. If hasnext is true: navigate {nexturl} → wait stable → re-run extract-listing.py
  3. If has_next is false: stop

Pagination

URL Pagination: extract-listing-next-page.py detects rel=next link, platform-specific pagination controls, and URL page parameters. Returns next_url for navigation.

DOM Pagination: For sites with load-more buttons (some Shopify themes):

  1. state to find "Load more" or "Show more" button
  2. click → wait stable → re-run extract-listing.py
  3. Termination: button no longer present, or item count stops increasing

Success Criteria

result.count >= 1 AND items[0].url != null

Known Limitations

  • Amazon: direct navigation may trigger bot detection on fresh sessions — navigate from https://www.amazon.com first
  • eBay listing pages may require navigating from https://www.ebay.com first
  • Google Shopping results have complex SPA structure and may have reduced accuracy; prefer direct site search when --site is specified
  • Filter URL parameters are site-specific; unsupported filter parameters are silently ignored by some sites
  • Shopify themes vary widely; if the generic DOM strategies miss items, check if the page has JSON-LD ItemList or Product array in page source

Execution Efficiency

  • Batch orchestration: Loop through pages serially within a single session; add 1–2 second intervals between page navigations
  • Test before batch execution: Test with 1 page before running multi-page extraction
  • Error resumption: Record page number; on failure, resume from the last successful page
