feat(code-interpreter): route Jupyter requests through the unified sandbox endpoint by devin-ai-integration[bot] · Pull Request #1963 · e2b-dev/E2B

devin-ai-integration · 2026-10-08T17:17:55Z

Summary

Code Interpreter Jupyter requests (/execute, /contexts…) now go through the unified sandbox endpoint (https://sandbox.<domain>) on supported domains, the same way the base SDK sends envd traffic. Routing relies on the E2b-Sandbox-Id / E2b-Sandbox-Port: 49999 headers these requests already sent.

JS: jupyterUrl calls connectionConfig.getSandboxUrl(...) instead of getSandboxDirectUrl(...). Browsers still use the per-port host (49999-<id>.<domain>) because of the existing CORS restriction in getSandboxUrl.
Python SDK: ConnectionConfig.get_sandbox_url / get_sandbox_direct_url take an optional port (defaults to the envd port), matching the port option JS getSandboxUrl / getSandboxDirectUrl already have.
```
def get_sandbox_url(self, sandbox_id: str, sandbox_domain: str, port: Optional[int] = None) -> str
```
Python Code Interpreter: sync and async _jupyter_url return connection_config.get_sandbox_url(sandbox_id, sandbox_domain, port=JUPYTER_PORT). Its e2b floor moves to >=2.55.0, the next minor given the pending changesets. The dedicated HTTP/1.1 Jupyter transport is unchanged.

User code doesn't change. Only the host the requests go to does:

sbx = Sandbox.create()        # E2B_DOMAIN=e2b.app
sbx.run_code("print(1)")      # before: POST https://49999-<id>.e2b.app/execute
                              # after:  POST https://sandbox.e2b.app/execute  (E2b-Sandbox-Id: <id>, E2b-Sandbox-Port: 49999)

Tested against prod (e2b.app): the full Code Interpreter JS (41) and Python (83) suites pass. run_code with streaming and the context create/list/restart/remove calls succeed through sandbox.e2b.app (sync and async).

LGTM — straightforward, well-tested routing change. Reviewed the jupyterUrl/_jupyter_url getters in all three implementations (JS, Python sync, Python async) against the base SDK's existing getSandboxUrl/get_sandbox_url pattern — they're logically equivalent, including the debug, sandbox_url-override, sandbox_domain-preference, and browser-CORS-fallback branches. The new/updated test suites (sandboxUrl.test.ts, test_sandbox_url.py) exercise each of those branches for both domains support and no-support cases.

Extended reasoning...

Small, self-contained change (6 files) that routes Jupyter/Code-Interpreter HTTP requests through the same sandbox.<domain> gateway the rest of the SDK already uses, falling back to the legacy per-port host on unsupported domains or in browsers. No auth/crypto logic is touched; the only security-relevant surface is which hostname the client connects to, and that logic mirrors the already-shipped ConnectionConfig.getSandboxUrl/get_sandbox_url implementations verified by reading connectionConfig.ts and connection_config.py. JS and both Python (sync/async) variants were changed in parallel and stayed logically equivalent, each with matching new tests, and a changeset was added.

This review covers commit 5337b3c, which is no longer the latest commit on this pull request; later commits are not covered by it.

On it. I'm switching to the base-SDK fix:

ConnectionConfig.get_sandbox_url / get_sandbox_direct_url get an optional port argument (defaults to the envd port, minor changeset for @e2b/python-sdk).
Code Interpreter calls get_sandbox_url(..., port=JUPYTER_PORT), and its own urls.py helper is removed.
The Code Interpreter e2b floor moves to >=2.55.0, the next minor given the pending changesets.

…quire e2b>=2.55.1 (#1967) ## Summary Hotfix: `e2b-code-interpreter` 2.10.4 on PyPI is broken. It requires `e2b>=2.55.0` and calls `connection_config.get_sandbox_url(..., port=JUPYTER_PORT)`, but the `port` argument from #1963 isn't in the published e2b 2.55.0. e2b 2.55.0 shipped at 09:34, and #1963 merged after that without a python-sdk changeset. Reproduced on a clean install against prod: ``` pip install e2b-code-interpreter==2.10.4 # resolves e2b 2.55.0 Sandbox.create().run_code("print(1)") # TypeError: ConnectionConfig.get_sandbox_url() got an unexpected keyword argument 'port' ``` The release then failed while trying to republish e2b 2.55.0 from the changed source: PyPI rejected it because `Local file and index file do not match` ([run](https://github.com/e2b-dev/E2B/actions/runs/37941620569/job/113858112984)). This PR: - adds a `@e2b/python-sdk` patch changeset, so `get_sandbox_url(..., port=)` ships as e2b 2.55.1 - adds a `@e2b/code-interpreter-python` patch changeset and raises its floor to `e2b>=2.55.1`, so `pip install -U e2b-code-interpreter` can't keep e2b 2.55.0 (2.10.5) `uv lock` in `packages/code-interpreter-python` produces no diff because uv ignores the specifier on workspace sources. After merging, run Release. Consider yanking `e2b-code-interpreter` 2.10.4 on PyPI.
