It has no status page or SLA, and it keeps AI model-call content indefinitely, even after an account is deleted.\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### Maritime\n\n1. Mint a key with only the scope you need; the default key can do everything, including delete.\n2. Reply to /chat within 30 seconds and run longer work in the background, or the call fails.\n3. Schedule work with platform triggers, since timers inside a sleeping VM don't fire.\n4. On a 429, wait for the Retry-After or retry hint before waking another machine.\n5. Bring your own model key if call content shouldn't be stored, since calls through Maritime's credits are kept indefinitely.\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, Maritime or SPACE?\n\nMaritime scores 66.5 (B) on agent readiness against SPACE's 56.2 (C), and leads in 4 of 7 scored categories. SPACE leads on security \u0026 auth, payments \u0026 pricing and transparency \u0026 trust.\n\n### Do Maritime and SPACE need an API key?\n\nMaritime needs an API key. SPACE takes an API key or an OAuth sign-in.\n\n### Can an agent call Maritime and SPACE without installing anything?\n\nMaritime has a hosted endpoint at https://mcp.maritime.sh/mcp. No hosted endpoint is listed for SPACE.\n\n### Are Maritime and SPACE open source?\n\nNo open-source release is listed for Maritime. SPACE is open source (Apache-2.0).\n\n\n## For agents\n\n- This comparison as JSON: https://www.anchorterminal.com/compare/maritime-vs-perplexity-space.json, and with the fewest tokens: https://www.anchorterminal.com/compare/maritime-vs-perplexity-space.min.md\n- Over MCP at https://www.anchorterminal.com/mcp (no key): `compare_tools {\"a\": \"maritime\", \"b\": \"perplexity-space\"}`.
