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
- Make sure the official x402 skill is installed (it handles automatic payment on 402 responses).
- 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.
