Frequently asked questions

It is a deterministic score across seven things autonomous shopping agents check — catalogue visibility, structured feed quality, live-deal freshness, discount depth vs comparable stores, agent checkout readiness, discoverability, and merchant control. We compute it from what is publicly observable about the storefront; no private data is used.

Pricing, stock, and live deals are refreshed on a regular cadence and shown with the date observed. The agent-readiness assessment only changes when the store’s underlying dynamics meaningfully change, so the narrative stays stable between routine refreshes.

No. Claiming verifies ownership on xpay and turns the link to your site into a followed backlink. It does not change anything on your own storefront or its search ranking.

This is an independent agent-readiness profile compiled by xpay from public information, similar to a directory listing. It exists to help shoppers and AI agents, and to let Four Sigmatic claim and control how agents see them.

Yes. Claiming the profile lets you correct catalogue, pricing, and policy details. If you would prefer not to be listed, you can request removal from the claim flow.
