One engineered core — catalog, prices, inventory and idempotent checkout — reachable over MCP, ACP, UCP and REST. No commerce backend to build, no signup to try. A retried request never charges twice.
Not a mockup — the demo's own output. complete_checkout_session is called, then called again with the same session.
The demo runs offline with no key and exits 0 only if one order came back. Run it yourself →
See it run — no signup
Press run: your browser issues a read-only sandbox key and reads the live demo catalog from api.ordercore.ai. No account, no credentials — the same API your agent will call.
Want to prove the retry guarantee itself? Ask the same endpoint for {"mode":"write"} and you get your own isolated tenant: create an order with an idempotency_key, send it again, and the same order comes back — a changed payload is refused with 409. Three curl calls, still no account. Worked example →
# Press "Run" — this makes a REAL call to the live API.
POST /bootstrap/sandbox-key # no signup, no key of your own
GET /v1/products # read the live demo catalogReal response, executed in your browser. Read-only. Rate-limited.
The part most agent-commerce gets wrong
Agents retry on a timeout, a rate limit, or a restarted loop. With naive checkout code, a retry is a second order and a second charge on a real card. OrderCore returns the same order on replay — and 409 conflict if the same key arrives with a different payload.
One interface
The same idempotent checkout core answers MCP, the ACP 2026-04-17 adapter, UCP and plain REST. Write it once — your agent talks to OrderCore however it already speaks. Same request, same guarantee.
// Any MCP client — Claude, Cursor, your agent loop
await mcp.callTool("checkout.complete", {
session: "cs_7P2",
idempotency_key: "order-abc-001" // retry-safe
});
// → 200 { order: "OC-2026-0001", status: "paid" } (same on replay)New / Transaction Trace
Inspect one purchase from order creation through status changes and every webhook attempt. Transaction Trace gives support and engineering one tenant-safe timeline without exposing raw webhook payloads.
Start in seconds
Point Claude, Cursor or any MCP client at OrderCore. No key needed — it runs a read-only sandbox. The public MCP server lives in cmd/ordercore-mcp.

Health, UCP discovery, the direct-AI tool manifest at /direct-ai/tooling and an independently-probed conformance report — inspect them yourself, anytime.
Same completion call returns the same order; same key + different payload returns 409. It's the product's core guarantee.
MIT examples + SDKs, an OpenAPI 3.1 spec you can import, Shopify App Store-listed, GDPR webhooks. No lock-in to try.

Hosted agent commerce gateway with a 3-day live trial.
A fixed-scope technical decision before you fund the implementation.
A scoped implementation sprint for one production order path.
Builder cancels through Stripe and access is suspended if renewal remains unpaid. Review and sprint begin only after written scope acceptance and payment.
Scan your current public surface first. If discovery is missing, the free report shows the first gaps. If the transaction model fits and your team can integrate an API, buy Builder. The USD 499 Agent Commerce Readiness Review is for the authenticated risks a public scan cannot prove.
No signup to see it work. A full key when you're ready.
