The product launched on 29 September 2026. No status page, OpenAPI file, SDK library or published rate limits were found, and the starter credit needs a card.\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### Agent 37 Cloud\n\n1. Send the key as `Authorization: Bearer` to api.agent37.com and as `X-Agent37-Key` to the instance URL. The Bearer form on instance URLs is deprecated\n2. Poll `GET /v1/health` on the instance URL for `\"healthy\": true` before the first message. `status: running` only means the machine is up\n3. Check whether `error` is a string before reading `error.code`. Transport errors are flat strings, and a failed turn returns 200 with `status: \"failed\"`\n4. Don't blindly retry an exec that timed out after 13 minutes. The command keeps running, so a retry starts a second copy\n5. Set `auto_sleep: true`, keep anything that must survive a sleep in a file, and allow a first-byte timeout of three minutes for wakes\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, Agent 37 Cloud or SPACE?\n\nSPACE scores 56.2 (C) on agent readiness against Agent 37 Cloud's 46.1 (D), and leads in 6 of 7 scored categories. Agent 37 Cloud leads on maintenance \u0026 community.\n\n### Do Agent 37 Cloud and SPACE need an API key?\n\nAgent 37 Cloud needs an API key. SPACE takes an API key or an OAuth sign-in.\n\n### Can an agent call Agent 37 Cloud and SPACE without installing anything?\n\nAgent 37 Cloud has a hosted endpoint at https://api.agent37.com/v1. No hosted endpoint is listed for SPACE.\n\n### Are Agent 37 Cloud and SPACE open source?\n\nNo open-source release is listed for Agent 37 Cloud. SPACE is open source (Apache-2.0).\n\n\n## For agents\n\n- This comparison as JSON: https://www.anchorterminal.com/compare/agent37-vs-perplexity-space.json, and with the fewest tokens: https://www.anchorterminal.com/compare/agent37-vs-perplexity-space.min.md\n- Over MCP at https://www.anchorterminal.com/mcp (no key): `compare_tools {\"a\": \"agent37\", \"b\": \"perplexity-space\"}`.
