waveium 0.4.0

Official Python SDK for the Waveium API

Waveium Python SDK

Official Python client library for the Waveium API. Build and run RF propagation simulations on top of a real environment model, stream progress via Server-Sent Events, and read the parquet results straight into a pandas DataFrame.

New here? Start with the step-by-step walkthrough at docs/getting_started.md.

Features

• Full coverage of the Environment -> Scene -> Execution workflow.
• Synchronous (waveium.Client) and asynchronous (waveium.AsyncClient) clients.
• Built-in SSE progress streaming with blocking wait() helpers and a create_and_run() convenience for the common case.
• read_parquet() streams result files straight into pandas without writing to disk; structured=True merges xyz triplets and complex re/im pairs for immediate analysis.
• Pydantic v2 models throughout for type safety.
• .env auto-loaded via python-dotenv.
• Typed exception hierarchy for precise error handling.

Installation

pip install "waveium[parquet]"

The [parquet] extra pulls in pandas and pyarrow, which client.executions.read_parquet() requires. Drop it if you only need to drive simulations without reading results in-process.

Python 3.9 or newer. Tested up to 3.13.

Quick start

import waveium

client = waveium.init()  # reads WAVEIUM_API_KEY from env / .env

# 1. Create an environment (outdoor, route-based).
env_resp = client.environments.create(
    name="Stockholm Route",
    environment_type="outdoor",
    route={
        "start": "Stockholm Central Station",
        "end": "Gamla Stan",
        "area": "Stockholm, Sweden",
    },
    stations={"BS1": [59.3293, 18.0686, 25.0]},
)
env = client.environments.wait(
    env_resp.environment.environment_id, timeout=900
)

# 2. Create and generate a scene.
scene = client.scenes.create(
    environment_id=env.environment_id,
    name="Default Scene",
    parameters={
        "stations": {"BS1": [59.3293, 18.0686, 25.0]},
        "station_radio_config": {
            "BS1": {"tx_power_dbm": 20.0, "noise_floor_dbm": -100.0}
        },
    },
)
client.scenes.generate(scene.scene_id)
client.scenes.wait(scene.scene_id, timeout=3600)

# 3. Run an execution and stream progress.
execution = client.scenes.create_and_run(
    scene.scene_id,
    execution_name="Quick Start",
    timeout=3600,
)

# 4. Read the parquet results into a DataFrame.
df = client.executions.read_parquet(
    execution.execution_id, structured=True
)
print(df.columns)
client.close()

Authentication

The SDK reads the API key from the WAVEIUM_API_KEY (or WAVEIUM_SDK_TOKEN) environment variable. Create keys at https://app.waveium.io.

Using a .env file (recommended)

WAVEIUM_API_KEY=wvx_paste_your_key_here

import waveium
client = waveium.init()  # .env auto-loaded

Passing the key explicitly

client = waveium.init(api_key="wvx_...")

Firebase JWT exchange

If you already have a signed-in Firebase user, exchange the JWT for a long-lived API key in one call:

client = waveium.auth(
    firebase_token="eyJ...",      # or set FIREBASE_TOKEN
    token_name="My Python App",
    expires_days=30,
)

Under the hood this POSTs the Firebase JWT to /auth/tokens with Authorization: Bearer <jwt> and returns a Client bound to the new wvx_ key.

Async usage

The AsyncClient mirrors the sync client one-for-one and works as an async context manager:

import asyncio
import waveium


async def main() -> None:
    async with waveium.AsyncClient() as client:
        execution = await client.scenes.create_and_run(
            "scn_xxx",
            execution_name="Async run",
            timeout=3600,
        )
        df = await client.executions.read_parquet(
            execution.execution_id, structured=True
        )
        print(df.head())


asyncio.run(main())

See examples/async_streaming_usage.py for the full set of async streaming patterns.

Available resources

Resource	Purpose

Error handling

All SDK errors inherit from waveium.WaveiumError:

from waveium import (
    WaveiumError,           # Base class
    AuthenticationError,    # 401
    AuthorizationError,     # 403
    NotFoundError,          # 404
    ConflictError,          # 409 (e.g. scene not completed yet)
    ValidationError,        # 400
    RateLimitError,         # 429
    APIError,               # 5xx
    NetworkError,           # connection / DNS / timeout
    FileUploadError,
    FileDownloadError,
    ConfigurationError,
    StreamError,
    StreamTimeoutError,
    StreamReconnectError,
    ExecutionFailedError,   # terminal "failed" SSE event
)

try:
    client.scenes.create_and_run(scene_id, timeout=3600)
except ExecutionFailedError as e:
    print(f"Execution {e.execution_id} failed: {e.error_message}")
except ConflictError:
    print("Scene is not in completed state yet")
except WaveiumError as e:
    print(f"SDK error: {e}")

Configuration

Variable	Meaning	Default
WAVEIUM_API_KEY	API key (starts with wvx_)	--
WAVEIUM_SDK_TOKEN	Alias for WAVEIUM_API_KEY	--
FIREBASE_TOKEN	Firebase JWT for waveium.auth()	--
WAVEIUM_BASE_URL	API base URL	https://api.waveium.io
WAVEIUM_TIMEOUT	HTTP timeout in seconds	60
WAVEIUM_MAX_RETRIES	Retry budget for idempotent requests	3

Override programmatically:

client = waveium.init(
    api_key="wvx_...",
    base_url="https://api.waveium.io",
    timeout=120.0,
    max_retries=5,
)

Examples

See the examples/ directory for runnable scripts. Each reads WAVEIUM_API_KEY from the environment (or a .env file).

Script	What it shows
basic_usage.py	Full Env -> Scene -> Execution pipeline, synchronous.
streaming_usage.py	Four tiers of SSE streaming (raw stream, blocking wait, create-and-run, environment wait).
async_usage.py	Async environment creation.
async_streaming_usage.py	Async counterparts of the streaming tiers.
load_and_plot.py	Minimal results-only script: point it at an execution_id to plot channel power and CIR.
helsinki_usage.py	Full outdoor Helsinki route: run the sim, download the parquet, and plot a 2D PDP.
helsinki_track_usage.py	Outdoor bbox variant: generate/upload a GPX track with timestamps as the UE trajectory, run the sim, download the parquet, and plot a 2D PDP.
upload_download.py	Scene file upload and execution result download.
underground_workflow.py	Complex underground scenario driven by JSON tunnel graph and CSV stations/UE, using polling.
underground_workflow_sse.py	Same scenario using SSE streaming instead of polling.
verify_sdk.py	Quick smoke test: init, users.me(), list environments.
