No hosted API. You deploy and secure a Worker before an agent can call anything, and the starter has no auth.\n\n**Maritime.** Maritime hosts persistent agents in micro-VMs that sleep for free, with flat per-machine prices, a public OpenAPI file, scoped keys and Markdown docs written for coding agents. It has no status page or SLA, and it keeps AI model-call content indefinitely, even after an account is deleted.\n\n## Before you call either\n\n### Cloudflare Sandbox SDK\n\n1. Derive the sandbox ID from the authenticated user, as the docs advise. IDs aren't secrets\n2. Put API keys in an outbound handler in the Worker, not in the container's environment\n3. Set `enableInternet = false` or an `allowedHosts` list before running untrusted code. Internet access is on by default\n4. Check that a restored backup has every directory you expect. Backups of 10 MB or more have open bugs\n5. Start new projects on 1.0. The 0.x library only gets fixes until 31 December 2026\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## Questions\n\n### Which is better for AI agents, Cloudflare Sandbox SDK or Maritime?\n\nCloudflare Sandbox SDK scores 67.5 (B) on agent readiness against Maritime's 66.5 (B), and leads in 3 of 7 scored categories. Maritime leads on schema \u0026 documentation, agent ergonomics, payments \u0026 pricing and maintenance \u0026 community.\n\n### Can an agent call Cloudflare Sandbox SDK and Maritime without installing anything?\n\nNo hosted endpoint is listed for Cloudflare Sandbox SDK. Maritime has a hosted endpoint at https://mcp.maritime.sh/mcp.\n\n### Are Cloudflare Sandbox SDK and Maritime open source?\n\nCloudflare Sandbox SDK is open source (Apache-2.0).
