UCP Solved the Transaction Protocol. DaaX LAKEer Solves the Trust Problem.
AI agents can now discover, check out, and transact on your customers' behalf through the Universal Commerce Protocol (UCP). But when an agent gets an answer wrong — a price, a warranty, a compatibility claim — it doesn't just answer wrong. It buys wrong.
DaaX LAKEer is the trust layer for agentic commerce: every product answer grounded in a knowledge graph and verified before your agent acts on it.
- Verified answers before checkout commits
- DaaX eCommerce Cartridge built on the GoodRelations ontology
There is no additional charge to use this Cartridge; to use it, merely activate it during LAKEer setup.
- Exposed as an MCP tool — UCP agents call LAKEer directly
- Works across catalogs, contracts, policies, and compliance docs
One Wrong Answer, One Wrong Transaction
UCP was launched in January 2026 with industry leaders including Google, Shopify, Etsy, Wayfair, Target, and Walmart, and endorsed by more than 20 others across the ecosystem — Adyen, American Express, Best Buy, Flipkart, Macy's Inc., Mastercard, Stripe, The Home Depot, Visa, and Zalando. It establishes a common language for AI agents to transact across the full shopping journey: discovery, checkout, and post-purchase support.
UCP solves the transaction protocol. It says nothing about whether the answers agents transact on are true.
The agent's query:
"Find a compatible charging dock for the ProBook X4 and order 200 units at our contract price."
Flat catalog lookup
Keyword-matches "ProBook dock" against product titles. Returns the X3 dock — the bestseller. Applies list price, not contract price. The agent orders 200 wrong units at the wrong price.
LAKEer verified answer
Traverses typed compatibility relationships (gr:QualitativeValue) in the DaaX 3D Graph: the X4 requires the Gen-2 dock. Validates the buyer's contract tier against gr:PriceSpecification. Verifies the answer, then returns it. The agent orders the right dock at the right price.
The difference isn't retrieval quality. It's that LAKEer reasons over structured knowledge and verifies before your agent acts — the category shift from eCommerce AI that retrieves and presents, to eCommerce AI you can let transact.
What LAKEer Does in the UCP Stack
The Truth Layer UCP Doesn't Have
UCP gives agents the ability to transact. DaaX GoodRelations gives those transactions semantic meaning. LAKEer gives them factual grounding and makes them verifiable. Plug the DaaX eCommerce Cartridge into LAKEer at setup, connect via MCP, and every agent answer is checked against your knowledge graph before it's returned.
UCP Catalog Capability Server
UCP's Catalog capability exposes product details to shopping agents — but a typical Catalog endpoint returns flat key-value attributes. Essentially a spreadsheet lookup. LAKEer answers from graph traversal and semantic search instead: gr:Offering, gr:PriceSpecification, and gr:WarrantyPromise are typed vertices in the DaaX 3D Graph, so agents asking for "compatible accessories" or "acceptable substitutes" get reasoned answers, not keyword hits.
Pre-Authorization Verification
UCP agents commit purchases on behalf of humans — and the current UCP stack doesn't verify that the price, warranty, or loyalty offer is factually accurate at the moment of transaction. LAKEer sits between your agents and checkout as a pre-authorization verification layer: Does the presented price match gr:PriceSpecification? Is the warranty claim consistent with actual gr:WarrantyPromise terms? Is loyalty eligibility real, or stale? Only verified transactions proceed.
Beyond the Storefront
The same cartridge powers the document-heavy back office of commerce. Query seller agreements and listing requirements for marketplace onboarding. Cross-reference recall notices against affected SKU lists and notification obligations. Resolve region-specific VAT and import rules for cross-border sales. Search carrier agreements and delivery SLAs in plain language — all exposed as MCP tools for internal teams and AI agents.
How It Works
Connect via MCP
Agents built on UCP — or any MCP-capable stack — call LAKEer directly. No custom integration.
Reason over the graph
LAKEer decomposes the query and traverses the DaaX 3D Graph, guided by the eCommerce Cartridge's typed relationships.
Verify, then answer
Every answer passes multi-stage verification before it returns. Your agent transacts on the truth.
Transact with confidence
LAKEer returns grounded, verified answers so your UCP agent can complete the purchase.
Why GoodRelations
GoodRelations is a formal OWL DL ontology authored by Martin Hepp to describe commercial transactions on the web. Since 2012 it has been substantially absorbed into Schema.org, making it the de facto eCommerce data model for structured web data — the same vocabulary behind rich snippets for product listings, pricing, and availability.
That ancestry matters. GoodRelations is not a data-management schema retrofitted for AI; it is a genuine domain ontology with typed classes, typed properties, and explicit domain/range constraints. Building on it means agents reason in the same vocabulary the open web already uses to describe offers, prices, warranties, and delivery.
And nearly every enterprise already has documents in this space — datasheets, vendor quotes, purchase orders, price lists, supplier agreements, warranty schedules. A procurement document corpus is essentially a GoodRelations knowledge base waiting to be extracted.
