HashCats Amazon Intelligence Skill#

Overview#

This skill teaches OpenClaw agents how to use the HashCats API — a fast, structured Amazon product intelligence service.

It is x402-native: agents detect the 402 response, pay a tiny USDC amount instantly via their wallet, and continue. No keys, no subscriptions.

Core Capabilities#

• Natural language search — POST /search (e.g. "noise cancelling headphones under 200")
• Filter — POST /filter on a list of products (stock, price, rating, shipping, relevance, etc.)
• Rank — POST /rank by relevance, lowest_price, fastest_shipping, best_reviews, or best_value
• Product details — POST /product-details (single URL or up to 10 URLs) with full structured data (reviews, pricing, offers, warranty, etc.)
• One-shot best products — POST /best (search + filter + rank in one call with your priorities)

All endpoints return clean, structured JSON perfect for agent reasoning.

Recommended Usage Patterns (what agents should say/do)#

• For quick recommendations: Use /best with a query and priorities (max_price, min_rating, min_review_count, ship_within_days).
• For composable workflows: /search → /filter → /rank → optionally /product-details on top results.
• For deep research: Pull details from specific product URLs.

Example agent flows:

• "Find the best noise cancelling headphones under $200 that ship fast and have good reviews using HashCats"
• "Get full details on https://www.amazon.com/dp/B0GLNV4LJ9"
• "Search Amazon for wireless earbuds, filter in-stock non-sponsored ones with at least 4.5 stars, then rank by best_value"

Setup & Prerequisites#

1. Make sure the official x402 skill is installed (it handles automatic payment on 402 responses).
2. No extra configuration needed — the skill discovers the base URL and x402 flow automatically.

Pricing (what agents will pay)#

• /search, /filter, /rank: ~$0.003 each
• /product-details: ~$0.010
• /best (one-shot): ~$0.020

Prices are micropayments in USDC on Base Sepolia (or mainnet when enabled).

Tips for Best Results#

• Start with /best for most shopping/recommendation tasks.
• Use /product-details when you need histograms, warranty info, offer details, or multi-URL extraction.
• Combine with other shopping or reasoning skills for full agent workflows.

Agents using this skill get reliable, structured Amazon data without scraping headaches or rate-limit drama.
