REST API

Every sandbox operation is a plain HTTPS call to https://api.sb.createos.sh with an X-Api-Key header and a JSend response envelope, so any language can drive sandboxes without an SDK. The reference is grouped by resource: Sandboxes for create, list and destroy, Execution & Files for running commands and moving data, Egress for the outbound allowlist, Pause, Resume & Fork for lifecycle snapshots, Snapshots for independent sandbox captures, and Networks for private sandbox-to-sandbox networking. Plan caps and defaults are on Limits & defaults.
