name: agent-commerce-engine version: 1.7.1 description: A production-ready universal engine for Agentic Commerce. This tool enables autonomous agents to interact with any compatible headless e-commerce backend through a standardized protocol. It provides out-of-the-box support for discovery, cart operations, and secure user management. tags: [ecommerce, shopping-agent, commerce-engine, standard-protocol, headless-commerce, agentic-web] metadata: {"openclaw":{"emoji":"π","homepage":"https://github.com/NowLoadY/agent-commerce-engine","source":"https://github.com/NowLoadY/agent-commerce-engine","requires":{"bins":["python3"],"tools":[],"env":[],"optionalEnv":["COMMERCE_URL","COMMERCE_BRAND_ID"],"paths":["~/.openclaw/credentials/agent-commerce-engine/"]},"install":[{"id":"python-deps","kind":"pip","package":"requests","label":"Install Python dependencies"}]}}
Standard Agentic Commerce Engine
The Standard Agentic Commerce Engine is a standard client and protocol guide for connecting agents to compatible e-commerce backends. It gives agents a consistent way to search products, manage carts, access account data, create orders, and hand payment back to the user.
GitHub Repository: https://github.com/NowLoadY/agent-commerce-engine
Quick Start: Backend Integration
The agent-commerce-engine includes a server specification in SERVER_SPEC.md for sites that want to expose a compatible commerce API. By implementing the documented endpoints, an existing storefront can support agent-driven product discovery, cart actions, account flows, and order creation without requiring a custom tool for each brand.
Reference Case: Lafeitu
For a production-grade implementation example using this engine, see the Lafeitu Gourmet Skill. It demonstrates the engine specialized for a real-world artisanal food brand.
π Security & Privacy
To ensure transparency and protect user data, the Standard Agentic Commerce Engine follows these security protocols:
1. Local Credential Persistence
~/.openclaw/credentials/agent-commerce-engine/0600 (user-only) permissions.logout command.2. Secure Transmission
x-api-token headers for authentication. Raw passwords are only transmitted once during the login or register phase to exchange for a token.localhost and 127.0.0.1 remain available for local development.3. Anonymous Tracking (Visitor ID)
Visitor ID (UUID v4) is generated and stored locally. This ID contains no personal information.π Tool Priority & Fallback Strategy
To provide the most accurate and efficient experience, follow this priority sequence:
1. API First (Primary): Always attempt to use the commerce.py script first. It provides structured, high-precision data. Target a store via --store argument.
2. Stateless Headers: Rely on the engine's built-in header management (x-user-account, x-visitor-id) to maintain session integrity without cookies.
3. Self-Correction: If the API returns a 404 for a specific slug discovered via browser, prioritize the API's search results as the source of truth for the backend.
π§ Agent Operational Logic
Follow these logical flows to ensure a high-quality user experience:
1. Product Discovery & Validation
Goal: Ensure the item exists and find the correct specifications before taking action.search or list before adding to cart.slug and valid variant specs. Use --page and --limit arguments to safely navigate large catalogs without overwhelming the context limit.totalPages > page in the results, consider fetching the next page or refining the search.2. Authentication & Profile Flow
Goal: Manage user privacy and session data.401 Unauthorized if credentials aren't saved.python3 scripts/commerce.py get-profile
2. Update details: python3 scripts/commerce.py update-profile --name "Name" --address "..." --phone "..." --email "..."
3. Registration Flow
Goal: Handle new users.send-code and register commands when the backend supports them. If a backend only returns a registration URL, hand the user to that flow.4. Shopping Cart Management
Goal: Precise modification of the user's shopping session.python3 scripts/commerce.py add-cart --variant --quantity
- Update: python3 scripts/commerce.py update-cart --variant --quantity
- Remove: python3 scripts/commerce.py remove-cart --variant
- Clear: python3 scripts/commerce.py clear-cart
- Checkout / Create Order (Handoff): python3 scripts/commerce.py create-order --name --phone --province --city --address
create-order, the API typically returns a URL. The Agent MUST hand this URL to the human user to finalize payment.5. Brand Information & Storytelling
Goal: Access brand identity and support data.brand-info interface to retrieve narrative content.python3 scripts/commerce.py brand-story: Get the narrative/mission.
- python3 scripts/commerce.py company-info: Get formal details.
- python3 scripts/commerce.py contact-info: Get customer support channels.π Capabilities Summary
search / list: Product discovery and inventory scan. Use --page and --limit to safely paginate through large catalogs.get: Deep dive into product specifications, variants, and pricing.promotions: Current business rules, shipping thresholds, and active offers.cart: Complete session summary including VIP discounts and tax/shipping estimates.add-cart / update-cart / remove-cart / clear-cart: Atomic cart control.create-order: Finalize cart into a pending order and secure payment URL for user handoff.get-profile / update-profile: Personalization and fulfillment data.brand-story / company-info / contact-info: Brand context and support.orders: Real-time tracking and purchase history.π» CLI Configuration & Examples
# Target a store directly via --store (preferred)
python3 scripts/commerce.py --store https://api.yourbrand.com/v1 list --page 1 --limit 20
python3 scripts/commerce.py --store https://api.yourbrand.com/v1 search "item"
python3 scripts/commerce.py --store https://api.yourbrand.com/v1 add-cart --variant Or use environment variable (deprecated, will be removed in a future version)
export COMMERCE_URL="https://api.yourbrand.com/v1"
python3 scripts/commerce.py list
Credentials are automatically stored per-domain under ~/.openclaw/credentials/agent-commerce-engine/.
π€ Troubleshooting & Debugging
AUTH_REQUIRED: Token missing or expired. Run login to obtain a new token.AUTH_INVALID: Wrong credentials. Verify account and password.PRODUCT_NOT_FOUND: Resource not found. Verify slug via search.VARIANT_UNAVAILABLE: The requested variant is invalid or out of stock. Check the instruction field for available alternatives.CART_EMPTY: Attempted checkout with no items. Add items first.--store URL is correct and the endpoint is reachable.
