purch-api

What This Skill Does

The purch-api skill is a powerful commerce engine that enables AI agents to search for products across Amazon and Shopify, and securely process payments using USDC on Solana or Base blockchains. This skill abstracts the complexity of e-commerce, allowing the agent to perform natural language product discovery and handle the backend logic for transaction generation. By connecting to https://api.purch.xyz, the agent can retrieve structured data including pricing, ratings, and source information, and act as a digital procurement assistant.

Installation

You can install the skill using the OpenClaw CLI by executing the following command in your terminal: clawhub install openclaw/skills/skills/purch-agent/agentic-commerce

Use Cases

1. Automated Shopping Assistants: Build custom chatbots that help users find products, compare prices across platforms, and complete purchases without leaving the chat interface.
2. Smart Procurement: Automate recurring product orders based on specific criteria or price thresholds using integrated crypto wallets.
3. Marketplace Aggregation: Centralize product search from diverse retailers like Amazon and Shopify into a single, unified interface for easier consumer decision-making.

Example Prompts

1. "Find me the best-rated mechanical keyboards under $150 and provide the direct purchase link."
2. "I need to buy a high-performance office chair. Find options on Shopify, compare them with Amazon, and prepare the payment transaction for the best one."
3. "Search for ergonomic standing desks, list the top 3 by rating, and guide me through a checkout using my Solana wallet."

Tips & Limitations

• Rate Limiting: The API is restricted to 60 requests per minute per IP. Monitor your X-RateLimit headers to prevent service interruptions during high-traffic tasks.
• Transaction Signing: Always verify the transaction details returned by the /buy endpoint before signing. Ensure your wallet has sufficient USDC balance on the correct network (Solana or Base) to avoid transaction failure.
• Scope: The skill defaults to USD currency. If you are browsing items internationally, ensure your checkout process accommodates the currency conversion or regional requirements of the merchant platform.
