agent-sandbox E2B SDK patch — one-line switch to use Agent Sandbox via the E2B Python SDK

agent-sandbox-e2b

A one-line patch that redirects the E2B Python SDK to a self-hosted Agent Sandbox deployment — no code changes to your existing E2B workflows required.

Agent Sandbox is a Kubernetes-native sandbox service for agentic AI scenarios (reasoning evaluation, training rollouts, code execution). It exposes an E2B-compatible API so you can reuse the E2B SDK while running on your own infrastructure.

Installation

pip install e2b agent-sandbox-e2b

Quick Start

Call patch_e2b() before importing Sandbox. It redirects all SDK requests to your Agent Sandbox cluster.

import os

os.environ["E2B_API_KEY"] = "agbx_your_api_key"

from agent_sandbox_e2b import patch_e2b
patch_e2b()  # zero-argument: uses default in-cluster addresses

from e2b import Sandbox

sandbox = Sandbox.create("POOL_NAME", timeout=3600, secure=False)
sandbox.commands.run("echo hello")
sandbox.kill()

Note: patch_e2b() must be called before any e2b import; otherwise the SDK connects to the official E2B service.

Cross-Cluster Usage

Prefix the pool name with a cluster ID to route requests across clusters:

sandbox = Sandbox.create("CLUSTER_ID::POOL_NAME", timeout=3600, secure=False)

Custom Image Override

Override the pool's default image at creation time:

# Using metadata key
sandbox = Sandbox.create(
    "POOL_NAME",
    timeout=3600,
    secure=False,
    metadata={"agentbox.scitix.ai/image": "registry.example.com/my-env:v2"},
)

# Shorthand syntax
sandbox = Sandbox.create(
    "CLUSTER_ID::POOL_NAME//registry.example.com/my-env:v2",
    timeout=3600,
    secure=False,
)

Configuration

patch_e2b() accepts optional arguments to override the target addresses:

Parameter	Default (in-cluster)	Description
domain	agent-sandbox-data-plane.agentbox-system.svc.cluster.local	Data-plane Envoy gateway address
api_url	http://agent-sandbox-e2b-api.agentbox-system.svc.cluster.local	E2B-compatible API URL
https	False	Use HTTPS for the data plane

Priority: explicit argument > E2B_DOMAIN / E2B_API_URL environment variables > built-in defaults.

# Local debugging via port-forward
patch_e2b(https=False, domain="localhost:9081", api_url="http://localhost:9082")

# Via environment variables (CI/CD)
# export E2B_DOMAIN=agent-sandbox-data-plane.agentbox-system.svc.cluster.local
# export E2B_API_URL=http://agent-sandbox-e2b-api.agentbox-system.svc.cluster.local
# export E2B_API_KEY=agbx_your_key
patch_e2b()

When using the Helm chart in a namespace other than agentbox-system, pass the installed namespace explicitly:

from agent_sandbox_e2b import patch_e2b

patch_e2b(
    domain="agent-sandbox-data-plane.my-namespace.svc.cluster.local",
    api_url="http://agent-sandbox-e2b-api.my-namespace.svc.cluster.local",
)

Compatibility

Release builds verify the patch against the latest E2B SDK from PyPI before publishing. After patching, all standard E2B SDK operations work unchanged:

sandbox.commands.run("python --version")
sandbox.commands.run("id", user="root")
sandbox.files.write("/tmp/hello.py", b"print('hello')\n")
sandbox.files.read("/tmp/hello.py")
sandbox.set_timeout(1800)   # extend idle timeout dynamically
sandbox.kill()
