What its author says it does

Copied from the file, not written here

Researches products, prices, sellers, and reviews across major online marketplaces (Amazon, eBay, Shopify stores, and Shop.app) 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 reviews — instead of scraping store pages.

Product & price research

Look up and compare products, prices, sellers, and reviews across Amazon, eBay, Shopify storefronts, and Shop.app — all as normalized JSON from the Crawlora API, with no HTML scraping.

When to use this skill

  • "What does X cost on Amazon / eBay?" or "compare prices for X across sellers."
  • "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.

Setup (one-time)

  • Get a free Crawlora API key (2,000 credits/mo, no card) at https://crawlora.net.
  • export CRAWLORA_API_KEY=sk_your_key_here
  • All requests: x-api-key: $CRAWLORA_API_KEY against 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 to find candidate products by keyword.
  2. Detail — fetch a specific product (/amazon/product, /ebay/item, /shopify/products/{handle}, /shop-app/products/{id}) for price, variants, specs.
  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).
  5. Compare the JSON fields (price, currency, rating, seller) and answer.

Full endpoint list, methods, and params: reference/endpoints.md.

Calling the API

# Search a marketplace (GET, key=value params):
scripts/crawlora.sh /amazon/search k="standing desk" | jq '.'
scripts/crawlora.sh /ebay/search q="mechanical keyboard" | jq '.'
scripts/crawlora.sh /shop-app/search query="running shoes" | jq '.'

# Product detail:
scripts/crawlora.sh /amazon/product asin=B0XXXXXXX | jq '{title,price}'

Raw curl fallback:

curl -fsS -H "x-api-key: $CRAWLORA_API_KEY" \
  "https://api.crawlora.net/api/v1/amazon/search?k=laptop" | jq '.'

Endpoint reference

See reference/endpoints.md for every Amazon, eBay, Shopify, and Shop.app endpoint this skill uses (method, path, params, description).

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.

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.
