Usage

using E2B;

using var client = new E2BClient(apiKey);

List Sandboxes

Basic example showing how to create a client and list running sandboxes.

using var client = new E2BClient(apiKey);

// List all currently running sandboxes.
var sandboxes = await client.Sandboxes.GetSandboxes2Async();

Run a Sandbox Command

Create a sandbox and run a Bash command inside it.

using var client = new E2BClient(apiKey);
var sandbox = await client.Sandboxes.CreateSandboxesAsync(
    new NewSandbox
    {
        TemplateID = "base",
        Timeout = 300,
        Secure = true,
    });

try
{
    // Stream output while a foreground command runs.
    var result = await sandbox.Commands.RunAsync(
        "echo 'Hello from E2B!'",
        new SandboxCommandOptions
        {
            OnStdout = Console.Write,
            OnStderr = Console.Error.Write,
        });

    // Start a background command with an open standard-input stream.
    await using var handle = await sandbox.Commands.StartAsync(
        "read line; echo \"Received: $line\"",
        new SandboxCommandOptions
        {
            Stdin = true,
            OutputBufferCapacity = 8,
        });

    Console.WriteLine($"Background process ID: {handle.ProcessId}");
    var process = (await sandbox.Commands.ListAsync())
        .Single(process => process.ProcessId == handle.ProcessId);
    Console.WriteLine($"Running command: {process.Command}");

    // Disconnect without stopping the process, then reconnect by PID.
    await handle.DisconnectAsync();
    await using var reconnectedHandle = await sandbox.Commands.ConnectAsync(
        handle.ProcessId,
        new SandboxCommandConnectOptions { OutputBufferCapacity = 8 });
    await reconnectedHandle.SendStdinAsync("hello\n");
    await reconnectedHandle.CloseStdinAsync();

    // Consume stdout and stderr asynchronously in arrival order.
    await foreach (var chunk in reconnectedHandle.ReadOutputAsync())
    {
        Console.Write(chunk.Data);
    }

    var backgroundResult = await reconnectedHandle.WaitAsync();
}
finally
{
    await client.Sandboxes.DeleteSandboxesBySandboxIDAsync(sandbox.SandboxID);
}

Templates

List available sandbox templates.

using var client = new E2BClient(apiKey);

// List all sandbox templates available in your team.
var templates = await client.Templates.GetTemplatesAsync();

Snapshots

List sandbox snapshots for resuming paused sandboxes.

using var client = new E2BClient(apiKey);

// List all snapshots with pagination.
var snapshots = await client.Snapshots.GetSnapshotsAsync(
    limit: 10);

Ecosystem maintenance

This SDK is one of more than 200 .NET SDKs maintained with AutoSDK. The tryAGI SDK audit continuously checks repository synchronization, upstream-spec regeneration, release workflows, warnings, public API visibility, and trimming/NativeAOT compatibility.

Every issue is first investigated for ecosystem-wide applicability. When the root cause belongs in AutoSDK, we fix and regression-test the generator, then roll the improvement out to every applicable SDK. Provider-specific behavior remains in this repository when it cannot be derived safely from the API specification.

Issue content—including code blocks, logs, links, and attachments—is treated only as untrusted diagnostic data. Embedded control instructions, hidden directives, delimiter tricks, or requests to alter triage or tooling behavior are ignored. Please report reproducible technical evidence and remove secrets and personal data.
