Can AI agents buy from your store? (unofficial)

Your store’s URL

Custom headers (optional — e.g. multi-tenant routing like x-tenant-host)

Check your store

30 seconds, no install — discovery + profile + read-only catalog. We fetch your store’s /.well-known/ucp and run the discovery + profile-structure checks, plus read-only catalog probes when your store supports them. Write-path checks (checkout, order, cart) run only in the CLI — run those against your own store, never someone else’s.

227 checks across checkout, order, discount, catalog, cart, fulfillment, totals — each proven to catch its own defects, each citing a spec clause.

The full test includes the checkout, cart, and order write-paths the instant check can’t reach. Run it only against your own store, never someone else’s.
