What it does

UCP is built by the industry, to enable seamless agentic experiences. It solves fragmented user journeys that lead to frustrated users and conversion drop off. Agentic commerce requires interoperability. UCP is built on industry standards — REST and JSON-RPC transports; Agent Payments Protocol (AP2) , Agent2Agent (A2A) , and Model Context Protocol (MCP) support built-in — so different systems can work together without custom integration.

  On January 11th, Google and Shopify announced the Universal Commerce Protocol (ucp.dev). It's an open standard that lets any application query products across e-commerce platforms without needing APIs, integrations, or middlemen. AskUCP is one of the first applications built on it. Right now, if you want to buy something online, you have to know which store sells it. You go to Amazon, or you go to a Shopify store, or you go to Etsy. Each one has its own search, its own interface, its own checkout. The experience is fragmented because the infrastructure is siloed. UCP changes this at the…

  isometric.nyc – giant isometric pixel art map of NYC▲1,325

  Hey HN! I wanted to share something I built over the last few weeks: isometric.nyc is a massive isometric pixel art map of NYC, built with nano banana and coding agents.

I wrote a deep dive on the workflow and some thoughts about the future of AI coding and creativity: http://cannoneyed.com/projects/isometric-nyc
