Agentic Commerce

Agentic commerce refers to AI agents — ChatGPT, Perplexity, Google AI Mode — autonomously discovering, evaluating, and purchasing products on behalf of users.

Why it matters

Traditional SEO optimizes for humans using search engines. Agentic commerce optimizes for AI agents that:

Don’t use web browsers — they query structured APIs
Make purchase decisions based on product data quality
Prefer stores with machine-readable catalogs and checkout APIs

A store without UCP support is invisible to these agents.

The agent flow

User tells an AI agent: “Buy me running shoes under $100”
Agent queries stores it knows about via their UCP manifests
Agent searches catalogs, compares products, picks the best match
Agent initiates a checkout session
Agent presents the continue_url to the user to complete payment

What makes a store agent-ready

Signal	Why agents care
UCP manifest at `/.well-known/ucp`	Discoverability — agents can find you
Rich product descriptions	Decision-making — agents understand your products
Correct pricing in minor units	Accuracy — no rounding or currency confusion
Working checkout API	Conversion — agent can initiate purchase
Structured data (JSON-LD)	Trust — cross-references catalog with web schema
