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**Together Code Sandbox.** Two public OpenAPI documents, MIT clients for Python and TypeScript, cursor pagination and built-in retries make the surface easy for an agent to drive. Access is the limit. Together enables the SDK per organisation on request, publishes no rate limits or SLA, and neither status page names the sandbox service.\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### Together Code Sandbox\n\n1. Confirm the organisation is on Together's allowlist before installing. A valid `TOGETHER_API_KEY` alone is not enough\n2. Build a snapshot first with `snapshots.create`. No default image exists, and every sandbox needs `snapshot_id` or `snapshot_alias`\n3. Set `ttl` at creation or call `terminate()`. Nothing stops a sandbox otherwise, and closing the Python client leaves it running\n4. Store the snapshot alias, not the sandbox ID. A terminated sandbox can't restart, and its state lives at `sandbox:\u003cid\u003e`\n5. Exclude `snapshots.create` from retries with `should_retry`, and set `experimental.network_policy` before serving anything private on a port\n\n## Questions\n\n### Which is better for AI agents, Agent 37 Cloud or Together Code Sandbox?\n\nTogether Code Sandbox scores 53.6 (D) on agent readiness against Agent 37 Cloud's 46.1 (D), and leads in 4 of 7 scored categories.\n\n### Do Agent 37 Cloud and Together Code Sandbox need an API key?\n\nBoth need an API key.\n\n### Can an agent call Agent 37 Cloud and Together Code Sandbox without installing anything?\n\nYes. Agent 37 Cloud has a hosted endpoint at https://api.agent37.com/v1 and Together Code Sandbox at https://api.bartender.codesandbox.io.\n\n\n## For agents\n\n- This comparison as JSON: https://www.anchorterminal.com/compare/agent37-vs-together-code-sandbox.json, and with the fewest tokens: https://www.anchorterminal.com/compare/agent37-vs-together-code-sandbox.min.md\n- Over MCP at https://www.anchorterminal.com/mcp (no key): `compare_tools {\"a\": \"agent37\", \"b\": \"together-code-sandbox\"}`.
