Standards are words and talk is cheap. A standard's success is measured by adoption, which is earned by solving right problems, with the right primitives, and running code. Universal Commerce Protocol has been a rocket ship. We chiseled it out of decades of shared experience running the world's largest commerce and consumer platforms, and it struck a chord, pulling contributors and adoption from across the agentic ecosystem. Case in point, the 04-08 release packed a punch. We landed support for: catalog for product discovery, cart building, post-order operations, context & intent for personalization, trust signals, and eligibility claims. Today the 🚀 trajectory accelerates. We're welcoming @amazon, @Meta, @Microsoft, @salesforce, and @stripe to the UCP Tech Council 🎉, working alongside @Google, @Shopify, @Etsy, @Target, and @Wayfair. Combined, these platforms touch billions of users, millions of merchants, and trillions of dollars in annual transactions — all rallying behind UCP as the one open protocol for the agentic era.

UCP 2026-04-08 is out 🎉 and it's a step function upgrade for agentic commerce 🦾 TL;DR: we've landed support for product discovery, cart building, personalization and eligibility claims across the full discovery→ cart→checkout journey, plus order tracking. UCP now covers the full purchase journey. 1/ 🔍 Catalog capability — enables product discovery via search query, lookup by ID, and get-product for fine-grained variant and option resolution. 2/ 🛒 Cart capability — enables basket building with live totals, discounts, and seamless handoff to checkout. Bonus: transport binding for embedded flows alongside MCP & REST. 3/ 🗒️ Order capability — new endpoint to retrieve order status by ID, complementing the existing webhook spec for real-time updates. 4/ 🙋 Context & intent fields — agents can now signal user intent and context so merchants can tailor results, offers, and experiences across catalog, cart, and checkout. 5/ 🔐 Signals — structured input for agents to pass authorization and abuse-prevention data to merchants. Trust negotiation, built into the protocol. 6/ 🪪 Eligibility claims — agents can assert verifiable claims (loyalty tier, membership, etc.) that merchants evaluate for conditional offers and discounts. 7/ ⚙️ And a *long* tail of other improvements: structured error model, request & response signing, version negotiation, disclosure messages for legal compliance, new delegation methods for embedded transport... the list goes on. Spec: ucp.dev/2026-04-08/specifica… Changelog, for the curious: github.com/Universal-Commerc… p.s. we're in the final stretch of polishing the Shopify implementation for all of the above - coming soon to every Shopify-powered storefront near you 😎.
