Verification: cloud examples on alicloud-express (2026-10-13)

Real Sandbox.create runs of the Python SDK examples that had not been executed against the cloud. Provider is the built-in default alicloud-express (ABX_PROVIDER unset). No image was pushed to ACR. Credential values are omitted.

Credentials

• /workspace/.env does not define ABX_SANDBOX_API_KEY or E2B_API_KEY.
• python-sdk/.env still has E2B_API_KEY and does not have ABX_SANDBOX_API_KEY. The client reads ABX_SANDBOX_API_KEY. The runner copied that existing key into ABX_SANDBOX_API_KEY inside the test process only. .env was not rewritten.
• E2B_API_URL and E2B_DOMAIN in python-sdk/.env equal the client defaults (https://api.cn-hangzhou.e2b.fc.aliyuncs.com, cn-hangzhou.e2b.fc.aliyuncs.com), so the process did not set ABX_SANDBOX_BASE_URL or ABX_SANDBOX_DOMAIN.
• OPENAI_API_KEY was not exported. examples/agents/codex_agent.py can simulate without it. examples/agents/browser_automation.py does not read a model key. No paid model call was made.
• The examples already read ABX_SANDBOX_API_KEY. No example source change was required.

How they were run

Working directory: /workspace/python-sdk. Interpreter: Python 3.12.3. PYTHONPATH=client-sdk/src:server-sdk/src.

Each example was started as python <example>. A thin wrapper logged Sandbox.create / Sandbox.kill (id, provider, template, TTL, elapsed) and, on create failure, stopped that example with exit 2 before another sandbox was created. After each example, Sandbox.list was checked for those ids.

Every create that returned an id used provider alicloud-express. Every such sandbox logged KILL_OK and was absent from the follow-up list. TTL is the timeout= each example already passes to Sandbox.create (seconds).

Preflight (not an example): Sandbox.create(template="base", timeout=60) then kill.

• Result: pass
• Elapsed: 3.66 s (create 1.75 s, kill 0.33 s)
• Sandbox id: sbx-11aee2db-acb6-4c18-ac64-f0a6d5a73248

Results

No example was skipped. Both agent scripts can start without a paid model key, so they were run. codex_agent.py failed at create, before its simulation branch.

examples/quickstart/03_web_service.py — pass

Command: python examples/quickstart/03_web_service.py

Create 2.64 s, kill 0.92 s. Template node-web. A capability warning said node-web fell back to DEFAULT_CAPABILITIES. The example still computed a public URL and the in-sandbox curls succeeded. X-Access-Token was printed by the example and is redacted here.

examples/agents/codex_agent.py — fail

Command: python examples/agents/codex_agent.py

Create failed before a sandbox id existed. The runner stopped the example (exit 2). Error code E2001.

CREATE_FAIL template=codex ttl=600 elapsed=1.10s code=E2001 type=TemplateNotFoundError
message=[E2001] template not found
Suggestion: Run 'abx template list' to see available templates.

OPENAI_API_KEY was absent from the process, so the paid branch would not have run. The script's simulation branch was not reached because create failed first.

examples/agents/browser_automation.py — fail

Command: python examples/agents/browser_automation.py

Create succeeded (1.46 s), template base. pip install playwright completed. The next command, playwright install chromium --with-deps, did not return a failed result; commands.run raised EnvdRpcError E3006:

[E3006] envd RPC /process.Process/Start failed (HTTP 500): exec: "playwright": executable file not found in $PATH

async with still killed the sandbox (kill 0.84 s). Follow-up list: absent. Exit 1. This script does not read OPENAI_API_KEY.

Cleanup

24 sandboxes were created (1 preflight + 23 example sandboxes). Each logged KILL_OK. A Sandbox.list(limit=100) after each example reported CLEANUP_ABSENT for every id from that example. codex_agent.py created none.
