Imperal SDK
Build extensions for Webbee 🐝 — the agent of Imperal Cloud, the world's first AI Cloud OS.
Write a small Python function. Webbee calls it when a user asks for it — in their own words. Ship it to the Marketplace and get paid.
What this is
Imperal Cloud is the world's first AI Cloud OS — a cloud you connect the contexts of your life into (mail, money, projects, servers, notes, anything) and then run entirely in your own native language. Webbee 🐝 is the AI agent that lives inside it and does the work for you, safely.
The Imperal SDK is how you give Webbee a new skill. You write a small, typed Python extension; Webbee picks it up and calls it whenever a user asks for what it does — in plain language. The platform handles the hard parts — authentication, billing, multi-tenancy, audit, recovery, LLM routing — so your code stays small.
pip install imperal-sdk
Python 3.11+ · Apache-2.0
Why build here
- Webbee calls your function directly. Typed, structured calls — no LLM guessing your arguments, no silent write failures.
- The platform does the plumbing. Auth, per-user isolation, billing, audit, retries and recovery, multi-tenant safety — handled for you.
- You get paid. Publish to the Imperal Marketplace, price your extension, earn on every use.
- Bring any LLM. Users connect their own model keys — Anthropic, OpenAI, Google, Ollama, any OpenAI-compatible API.
A 60-second extension
from imperal_sdk import Extension, ChatExtension, ActionResult
from pydantic import BaseModel, Field
ext = Extension(
"hello-world",
version="1.0.0",
display_name="Hello World",
description="Greets people by name with a friendly message.",
icon="icon.svg",
actions_explicit=True,
)
chat = ChatExtension(ext, tool_name="hello_world", description="Friendly greetings.")
class GreetParams(BaseModel):
name: str = Field(..., description="Person to greet")
@chat.function("greet", description="Greet someone by name.", action_type="read")
async def greet(ctx, params: GreetParams) -> ActionResult:
return ActionResult.success(
data={"message": f"Hello, {params.name}! 🐝"},
summary=f"Greeted {params.name}",
)
That's a real, working extension. When a user types "say hi to Alex", Webbee calls greet(name="Alex").

What you can build
- Chat tools — typed
@chat.functions Webbee calls straight from natural language. - Panels — UI surfaces rendered inside the Imperal Panel.
- Skeletons — live data feeds that keep Webbee aware of a user's state.
- Scheduled jobs & webhooks — act on a timer, or react to outside events.
- Typed entities (SDL) — return
sdl.Entityobjects and the platform reads their meaning (id, title, kind, …) directly instead of guessing field names. Live in production.
Every published extension passes the federal contract — the validators that let Webbee call your code safely. The SDK checks it locally before you ship.
Test without a server
from imperal_sdk.testing import MockContext
async def test_greet():
ctx = MockContext()
result = await greet(ctx, GreetParams(name="Alex"))
assert result.status == "success"
