Function Compute:Public Access

Start and access a service

TypeScript example:

import { Sandbox } from "e2b";

const sandbox = await Sandbox.create("code-interpreter-v1", {
  apiKey: process.env.E2B_API_KEY,
  apiUrl: process.env.E2B_API_URL,
  domain: process.env.E2B_DOMAIN,
});

try {
  const process = await sandbox.commands.run("python3 -m http.server 8000", {
    background: true,
  });

  const host = sandbox.getHost(8000);
  const url = `https://${host}`;
  console.log(url);

  const response = await fetch(url);
  console.log(await response.text());

  await process.kill();
} finally {
  await sandbox.kill();
}

Python example:

import os
import urllib.request

from e2b import Sandbox

sandbox = Sandbox.create(
    template="code-interpreter-v1",
    api_key=os.environ["E2B_API_KEY"],
    api_url=os.environ["E2B_API_URL"],
    domain=os.environ["E2B_DOMAIN"],
)

try:
    process = sandbox.commands.run(
        "python3 -m http.server 8000",
        background=True,
    )

    host = sandbox.get_host(8000)
    url = f"https://{host}"
    print(url)

    with urllib.request.urlopen(url, timeout=10) as response:
        print(response.read().decode())

    process.kill()
finally:
    sandbox.kill()

Notes

• Before calling getHost(port), make sure a service inside the sandbox is already listening on that port.

• getHost(port) returns a host value, so you usually need to prepend https:// when constructing the URL.

• Background services do not stop automatically. Stop the process or terminate the sandbox when the task finishes.

• Do not expose sensitive data, internal debugging interfaces, or long-lived credentials through unauthenticated port services.
