Python SDK for AgentTier — isolated, persistent Kubernetes sandboxes for humans and AI agents

AgentTier Python SDK

Programmatic client for AgentTier — manage isolated, persistent Kubernetes sandboxes for humans and AI agents from Python.

pip install agenttier

Synchronous quick start

from agenttier import AgentTierClient

with AgentTierClient(api_url="https://agenttier.company.com") as client:
    sandbox = client.create_sandbox(template="general-coding", name="demo")
    sandbox.wait_until_running()

    result = sandbox.exec("echo 'hello from AgentTier'")
    print(result.stdout, "exit", result.exit_code)

    port = sandbox.forward_port(8080)
    print("Forwarded:", port.preview_url or port.internal_url)

    sandbox.terminate()

Async

import asyncio
from agenttier import AsyncAgentTierClient

async def main():
    async with AsyncAgentTierClient(api_url="https://agenttier.company.com") as client:
        sandbox = await client.create_sandbox(template="general-coding", name="demo")
        await sandbox.wait_until_running()
        result = await sandbox.exec("uname -a")
        print(result.stdout)
        await sandbox.terminate()

asyncio.run(main())

Authentication

The SDK auto-detects credentials in this order:

1. AGENTTIER_API_KEY — sent as X-API-Key.
2. AGENTTIER_TOKEN — sent as Authorization: Bearer <token> (OIDC JWT).
3. In-cluster ServiceAccount token at /var/run/secrets/kubernetes.io/serviceaccount/token.
4. Unauthenticated (accepted only in the Router's dev mode).

Or pass an explicit provider:

from agenttier import AgentTierClient, APIKeyAuth, BearerTokenAuth

client = AgentTierClient(
    api_url="https://agenttier.company.com",
    auth=APIKeyAuth("sk_live_..."),
)

Error handling

Every error inherits from AgentTierError so you can catch them all at once. The common subclasses you'll want to handle individually:

Exception	When
AuthenticationError	401 — token / API key missing or invalid
AuthorizationError	403 — authenticated but not permitted
PolicyViolationError	403 with governance body; exposes .violations
NotFoundError	404 — resource doesn't exist
ConflictError	409 — operation invalid for current state
SandboxTimeoutError	wait_until_running timed out
SandboxErrorState	sandbox entered the Error phase while waiting
APIError	anything else; carries .status_code and .body

Supported API surface (v0.1.1)

Only endpoints that the Router server implements in v0.1.0 are exposed:

• Sandboxes — create_sandbox, list_sandboxes, get_sandbox, stop, resume, terminate, exec, wait_until_running, status.
• Port forwarding — forward_port, list_ports, remove_port.
• Templates — list_templates, get_template.
• Identity — current_user.

Endpoints that are not yet implemented on the server (file transfer, sharing, cloning, WebSocket terminal from Python) are not exposed by the SDK and will be added in a future release once the server ships them.

Supported Python versions

3.10, 3.11, 3.12, 3.13. Runtime dependencies: httpx and pydantic.
