No REST API, and the JavaScript and Go SDKs are beta.\n\n**SPACE.** Once deployed, SPACE's native API has a public OpenAPI 3.1 contract, stable error codes with a retryable flag and 24-hour idempotency keys, and egress and credential controls sit outside the VM. A person must first deploy it on a Linux x86_64 host with KVM and Kubernetes. Version 0.8.0 has no tagged release, changelog or public container images.\n\n## Before you call either\n\n### Modal Sandboxes\n\n1. Pass `timeout=` when you create a sandbox. The default lifetime is 5 minutes\n2. Set `block_network=True` or a `cidr_allowlist` for untrusted code\n3. Give a sandbox a `name` so a retried create raises `AlreadyExistsError` instead of starting a second one\n4. Snapshot the filesystem before the 24-hour limit and start a fresh sandbox from it\n5. Catch `ResourceExhaustedError` from `Sandbox.create()` on SDK 1.6.0 and later\n\n### SPACE\n\n1. Ask your operator for the API base URL (before `/v1`, or `/api/v1` on shared hosts), the data-plane URL and a bearer token before planning any call\n2. Poll the returned operation until it succeeds and the sandbox is `running` before creating a command. A 202 response is not readiness\n3. Attach to the command's events URL with its session token to start the process, decode base64 output, and treat only `process_exited` as completion\n4. Send an `Idempotency-Key` on creates, lifecycle calls and commands, and retry only when `retryable` is true, after any `Retry-After`\n5. Save output as it arrives. Reconnecting with `Last-Event-ID` returns `resync_required`, not the missed output\n\n## Questions\n\n### Which is better for AI agents, Modal Sandboxes or SPACE?\n\nModal Sandboxes scores 75.5 (BB) on agent readiness against SPACE's 56.2 (C), and leads in 6 of 7 scored categories.
