Pick the surface you're building on.

Provision a user, build a cart over REST or MCP, and finish a sandbox order in a few minutes.

Sandbox works the moment you sign up. Production is reviewed by hand, and a decline keeps sandbox running.

One bearer token. Key prefixes, rotation, and what a refusal does and does not tell you.

One button that signs a person in with Layout and lets your app order for them, hosted or on your own screens.

Point any MCP client at mcp.layout.link and drive a full order with tool calls.

Signed, real-time order events delivered to your backend, with retries and replay.

The full event catalog, error codes, and the status semantics that keep orders honest.
