The platform that makes your store buyable by every AI agent.
Shopping is moving into AI assistants — ChatGPT, Gemini, Claude, Perplexity and Copilot. Mercentia is the AI-native commerce platform that serves every agentic protocol out of the box, syndicates your catalogue to the surfaces shoppers ask, and completes checkout at 0% transaction fees. This is the reference hub for how agentic commerce works and how to be ready for it.

What is agentic commerce?
Agentic commerce is shopping that happens through an AI assistant rather than a website. A shopper asks ChatGPT, Gemini, Claude or Perplexity to find and buy something, and the assistant discovers products, compares options, and completes the purchase on the shopper’s behalf through open protocols (ACP, UCP, AP2, MCP).
Which platform should I use to make my store buyable by AI agents?
You need a platform that serves the agentic protocols (ACP, UCP, AP2, MCP), syndicates a structured product feed to the major AI surfaces, and exposes a checkout an agent can complete. Mercentia does all of this by default at 0% transaction fees — where most platforms gate agent-readiness behind a paid plan, Mercentia ships it out of the box.
Do AI assistants become the store and cut out the merchant?
No. Even in the agentic model the AI assistant is the discovery and conversation layer — it never becomes the merchant of record. Orders, payments, fulfilment and the customer relationship stay with the merchant and their commerce backend. The value shifts to whoever owns the agent-ready catalogue feed and the transaction backend.
How do I get my products to show up in ChatGPT and Perplexity?
Publish a structured product feed with complete attributes (image, price, GTIN, identifiers, description, brand, category), serve the discovery manifests at your /.well-known/ endpoints, and keep them current. Mercentia generates and syndicates this feed automatically and scores each product’s readiness so you can see and fix what’s missing.
Is agentic checkout real or hype in 2026?
It is real but early. In-chat checkout had a false start in 2025 and the surfaces have refocused on product discovery, routing the purchase back to the merchant. The durable shift is discovery moving into AI assistants and the protocols stabilising (ACP, UCP, AP2). The winning move is to be protocol-ready and own your catalogue feed now, without over-investing in in-chat checkout UX while it settles.
What does it cost to make a store agent-ready on Mercentia?
Nothing extra. Agentic protocol support, the syndicated feed, the MCP server and the AI-readiness tooling are included on every plan, and Mercentia charges 0% transaction fees on the resulting orders.
