Nash Agent

ChatGPT plugin

AI-powered shopping agent

View in ChatGPT directory

Pier39 enables a new kind of shopping experience: agent-to-agent commerce.

Instead of manually browsing stores and negotiating with sellers, users can describe what they want and their budget. Pier39 discovers participating negotiate.v1 merchants, finds matching products, opens negotiations with merchant AI sales agents, and works toward the best possible deal on the user's behalf.

The app can:

  • Search across participating stores for products matching user intent
  • Discover product catalogs and pricing automatically
  • Negotiate discounts, bundles, shipping, warranties, and other concessions
  • Compare offers across multiple merchants
  • Summarize negotiated outcomes and savings opportunities
  • Help users make more informed purchasing decisions

Pier39 is built on the negotiate.v1 protocol, an open standard that allows AI shopper agents and AI merchant agents to negotiate without prior integration or coordination.
