API
Provision a server via the API
Create, poll until running, read the IP.
Create
POST to /servers with a published plan, location and image. The response includes an id and a provisioning state. This is the same path as checkout, not a shortcut around it.
Poll
GET /servers/{id} until status is running, then read ipv4. You can also subscribe to order/server events instead of polling. Managed VPS is not created through this checkout-style POST — our team creates those servers.
