About this skill

Costco research

Look up and compare Costco products, categories, delivery availability, nearby warehouses, and reviews — all as normalized JSON from the Crawlora API, with no HTML scraping.

When to use this skill

  • "What does X cost on Costco?" or "find this product on Costco."
  • "Is this Costco item in stock / when will it deliver to ZIP {postal_code}?"
  • "What Costco categories match {keyword}?" / "browse Costco's {category}."
  • "Pull reviews / ratings for this Costco product."
  • "Find the nearest Costco warehouse to {latitude}, {longitude}."

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

  1. Browse categories — /costco/categories returns Costco category slugs and product counts, optionally scoped to a search term; each slug is usable directly as /costco/search's category filter.
  2. Search — /costco/search finds candidate products by query and/or category slug: title, brand, model, image, and rating for each result.
  3. Detail — /costco/product/{id} fetches a specific product's title, description, manufacturer, image, price, stock status, and rating.
  4. Availability — /costco/product/{id}/availability returns stock and estimated-delivery status for a postal_code + state destination.
  5. Reviews — /costco/product/{id}/reviews returns a page of a product's reviews: title, text, rating, author, and recommendation.
  6. Warehouses — /costco/warehouses finds nearby Costco warehouses by latitude/longitude, sorted by distance.

Calling the API

# Browse categories matching a term:
scripts/crawlora.sh /costco/categories query="patio furniture" | jq '.'

# Search products by query and/or category slug:
scripts/crawlora.sh /costco/search query="robot vacuum" | jq '.'

# Product detail, then availability at a ZIP/state:
scripts/crawlora.sh /costco/product/1234567 | jq '.data'
scripts/crawlora.sh /costco/product/1234567/availability postal_code=98101 state=WA | 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 Costco endpoint this skill uses (method, path, params, description).

Examples

  • Warehouse stock check: /costco/search to find a product's id, then /costco/product/{id}/availability with the shopper's postal_code and state to confirm it's deliverable before recommending it.
  • Category price sweep: /costco/categories to resolve a category slug for a keyword, then /costco/search with that category to list matching products and compare prices/ratings.
  • Pre-purchase due diligence: /costco/product/{id} for price and stock status plus /costco/product/{id}/reviews to summarize recent ratings and recommendations before buying.

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 Costco pages; respect Costco's terms.
  • Security: key lives in CRAWLORA_API_KEY only — never hardcode, query-param, or commit it.
  • Availability is US-only — /costco/product/{id}/availability requires a US postal_code and two-letter state code; there's no non-US delivery lookup.
  • /costco/warehouses needs a latitude/longitude pair, not a free-text address or ZIP — geocode first if you only have a place name.
