product-price-research

Researches products, prices, sellers, and reviews across major online marketplaces and big-box/specialty retailers (Amazon, eBay, Shopify stores, Shop.app, Target, Costco, Walmart, Nike, Zara, Adidas, Best Buy, Home Depot, Sephora, SHEIN, IKEA, Chewy, and more) using the Crawlora API, returning clean JSON. Use when the user asks to find a product, compare prices or sellers, track listings, or pull marketplace/retailer reviews — instead of scraping store pages.

Look up and compare products, prices, sellers, and reviews across Amazon, eBay, Shopify storefronts, Shop.app, Target, Costco, Zalando, Walmart, H&M, Kohl's, Lululemon, Macy's, Nike, Old Navy (plus Gap, Banana Republic, and Athleta under the same endpoints), Sam's Club, Ulta Beauty, Wayfair, Wish, Zappos, Zara, Adidas, Best Buy, Home Depot, Sephora, SHEIN, IKEA, and Chewy — all as normalized JSON from the Crawlora API, with no HTML scraping. Walgreens is store-locator only (no product catalog).

When to use this skill

• "What does X cost on Amazon / eBay / Target / Walmart?" or "compare prices for X across sellers/retailers."
• "Find listings for X" / "search this Shopify store" / "what's in this collection?"
• "Pull reviews / ratings for this product or seller."
• "Track this product's price / variants / availability."
• Competitive pricing, catalog, or marketplace-review research.
• "Browse category X on Wayfair / Kohl's / Sam's Club" when the retailer has no keyword search of its own.
• Apparel/beauty catalog lookups spanning Nike, Zara, H&M, Old Navy/Gap/Banana Republic/Athleta, Lululemon, Ulta Beauty, Adidas, or Sephora.
• Home-goods/electronics/pet lookups spanning Home Depot, Best Buy, IKEA, or Chewy.
• "Find the nearest Walgreens" (store locator only — no product catalog).

Setup (one-time)

• Get a free Crawlora API key (2,000 credits/mo, no card) at https://crawlora.net.
• Set CRAWLORA_API_KEY in the environment before running the helper.
• The helper reads CRAWLORA_API_KEY from the environment and sends requests to https://api.crawlora.net/api/v1. Missing/invalid key → 401.

How it works

Pick the marketplace, then the job:

1. Search / discover — /amazon/search, /ebay/search, /shopify/products, /shop-app/search, /target/search, /costco/search, /walmart/search, /hm/search, /nike/search, /oldnavy/search (covers Old Navy, Gap, Banana Republic, and Athleta via brand=on|gap|br|at, defaults to on), /ulta/search, /wish/search, /zappos/search, /zara/search (requires section, a department like WOMAN/MAN), and /zalando/search (this one requires market — a Zalando country storefront code like de, fr, com; list them via /zalando/markets) to find candidate products by keyword. Kohl's, Lululemon, Macy's, Sam's Club, and Wayfair have no keyword-search endpoint — browse a category instead: /kohls/category (facets give follow-up category strings), /lululemon/categories → /lululemon/category, /samsclub/departments → /samsclub/category, and /wayfair/categories → /wayfair/category. Macy's has neither search nor category browse at all — only direct productId lookup (below) plus /macys/suggest typeahead. /adidas/search (query or category, exactly one required), /bestbuy/search (q), /homedepot/search (q), /sephora/search (query, plus brand/filter/price_min+price_max as a matched pair/rating_min/is_new facets), /ikea/search (q, or an IKEA item number resolves directly), and /chewy/search (q — a strong category match like "dog food" transparently redirects to that category listing) round out search. Walgreens has no product catalog at all — /walgreens/stores (lat/lon or zip) is its only endpoint, for store lookup.
2. Detail — fetch a specific product (/amazon/product, /ebay/item, /shopify/products/{handle}, /shop-app/products/{id}, /target/product (tcin), /costco/product/{id}, /walmart/product/{item_id}, /zalando/product (sku+market), /hm/product/{product_id}, /nike/product (slug+style_color), /oldnavy/product (pid+brand), /lululemon/product/{product_id}, /macys/product/{productId}, /samsclub/product/{id}, /ulta/product/{productId}, /wayfair/product/{id}, /wish/product/{id}, /zappos/product/{productId}, /zara/product/{productId}, /adidas/product (product_id), /bestbuy/product (sku), /homedepot/product/{id}, /sephora/product (product_id — the full product-page slug like lip-sleeping-mask-P420652, not just the SKU), /shein/products/detail (goods_id+goods_sn), /ikea/product (item_no), /chewy/product (id)) for price, variants, specs. Kohl's has no standalone product-detail endpoint — product cards (including web_id, needed for reviews below) only come back embedded in /kohls/category's listing.
3. Sellers — for eBay/Shop.app, resolve the seller/shop (/ebay/seller/..., /shop-app/shops/{handle}) to compare offers.
4. Reviews — pull product/seller reviews where available (/shop-app/products/{id}/reviews, /ebay/seller/.../feedback, /target/reviews, /costco/product/{id}/reviews, /walmart/product/{item_id}/reviews, /kohls/product/reviews (web_id), /macys/product/reviews (product_id), /nike/product/reviews (slug+style_color), /oldnavy/product/reviews (pid+brand), /ulta/product/reviews (product_id), /wish/product/{id}/reviews). H&M, Lululemon, Sam's Club, and Zappos surface reviews (when present) embedded in their own product-detail call instead of a separate endpoint; Wayfair and Zara expose no reviews at all — Wayfair's product detail only has an aggregate rating. /bestbuy/product/reviews (sku), /sephora/product/reviews (product_id), and /ikea/reviews (item_no) cover those three separately; Home Depot and Chewy surface reviews embedded in their own product-detail call instead. Adidas reviews and rating summaries are available at /adidas/product/reviews, using the search result's model_number (not its SKU). Discover per-model review topics via /adidas/product/review-topics; locale controls review language and can yield an empty review sample. SHEIN exposes no review endpoint in this catalog.
5. Compare the JSON fields (price, currency, rating, seller) and answer.

Calling the API

sh

# Search a marketplace (GET, key=value params):
scripts/crawlora.sh /amazon/search k="standing desk" | jq '.'
scripts/crawlora.sh -X POST /ebay/search '{"keyword":"mechanical keyboard"}' | jq '.'
scripts/crawlora.sh /shop-app/search query="running shoes" | jq '.'
scripts/crawlora.sh /target/search q="standing desk" | jq '.'
scripts/crawlora.sh /walmart/search q="standing desk" | jq '.'
scripts/crawlora.sh /zalando/search q="running shoes" market=de | jq '.'
scripts/crawlora.sh /nike/search keyword="running shoes" | jq '.'
scripts/crawlora.sh /ulta/search query="retinol serum" | jq '.'
scripts/crawlora.sh /bestbuy/search q="laptop" | jq '.'
scripts/crawlora.sh /sephora/search query="retinol serum" | jq '.'
scripts/crawlora.sh /chewy/search q="salmon dog food" | jq '.'

# Product detail:
scripts/crawlora.sh /amazon/product/B0XXXXXXX | jq '.data'
scripts/crawlora.sh /ikea/product item_no=00263850 | jq '.'

# Category browse (no keyword search on this platform):
scripts/crawlora.sh /wayfair/category category=478390 | jq '.'
scripts/crawlora.sh /zara/category/2420463/products | jq '.'

# Store locator only (no product catalog):
scripts/crawlora.sh /walgreens/stores zip=10001 | jq '.'

Use scripts/crawlora.sh for all requests; it keeps the API key out of command-line arguments.

Endpoint reference

See reference/endpoints.md for every endpoint this skill uses, including its method, path, parameters, and platform coverage.

Examples

• Cross-marketplace price compare: search /amazon/search and /ebay/search for the same query, collect price from each, and present the spread.
• Seller due diligence: /ebay/seller/{seller} + /ebay/seller/{seller}/feedback to summarize a seller's rating and recent feedback before buying.
• Shopify catalog audit: /shopify/products (paginate) to list a store's catalog with prices, then flag items above/below a threshold.
• No-search retailer browse: for a retailer with no keyword search (Kohl's, Wayfair, Sam's Club), call the category/department-discovery endpoint first (/kohls/category's facets, /wayfair/categories, /samsclub/departments) to find a category id, then browse it directly instead of trying to search by keyword.

Notes & limits

• Credits / pay-on-success: billed only on 2xx; free tier 2,000 credits/mo. Key at https://crawlora.net.
• Public data only — public product/listing pages; respect each marketplace's terms.
• Security: key lives in CRAWLORA_API_KEY only — never hardcode, query-param, or commit it.
• Results are paginated — pass page (and count where supported) to walk listings.
• Zalando always needs market (no default storefront) — resolve valid codes via /zalando/markets if unsure.
• Macy's has no search or category browse — only /macys/product/{productId} (needs a known productId) and /macys/suggest typeahead.
• Wayfair has no search and no reviews endpoint — only /wayfair/categories → /wayfair/category and /wayfair/product/{id} (which carries an aggregate rating, but no review text).
• Kohl's has no search or standalone product-detail endpoint — browse /kohls/category (its category param takes a +-joined taxonomy string, percent-encode the + as %2B) and read product cards from the listing; /kohls/product/reviews needs the web_id from that listing.
• Sam's Club has no keyword-search endpoint — start from /samsclub/departments or /samsclub/category; there's also no dedicated reviews endpoint (rating/review count only comes from /samsclub/product/{id}).
• Lululemon has no keyword-search endpoint — browse via /lululemon/categories → /lululemon/category; reviews are embedded in /lululemon/product/{product_id}, not a separate call.
• Zara's /zara/search requires section (a department like WOMAN), and Zara exposes no reviews endpoint at all.
• Old Navy's endpoints are shared across four storefronts — pass brand=on|gap|br|at (Old Navy/Gap/Banana Republic/Athleta; defaults to on); a cid/pid found under one brand only works with that same brand.
