piaa-sdk (Official Python SDK)

Official, production-grade Python SDK for the PIA Market Intelligence & Realtime Financial Platform.

Designed for institutional quantitative trading bots, financial analytics, fintech backends, and data science workflows.

Key Features

• Simple, Intuitive API: Start fetching market data in under 3 lines of code with zero unnecessary ceremony.
• Cross-Platform Realtime Streaming: Resilient WebSocket client featuring In-Band Message Authentication, ping/pong keep-alives, auto-reconnect, and dynamic symbol subscriptions.
• Typed Exception Hierarchy: Actionable exceptions (AuthenticationError, RateLimitError, TimeoutError, ValidationError, NetworkError) with detailed quota telemetry attributes.
• Zero Sensitive Data Leaks: Automatic regex redaction of wi_live_... API keys and Bearer tokens in error strings and logs.
• Dual Sync & Async Support: Both synchronous (PiaClient) and modern asyncio (AsyncPiaClient) interfaces available.
• Type Hinting: Fully typed with PEP 561 py.typed marker for flawless IDE autocompletion and MyPy verification.

Installation

pip install piaa-sdk

Quickstart

1. Synchronous REST API

from pia import PiaClient, RateLimitError, AuthenticationError

# Automatically picks up os.environ["PIA_API_KEY"] if omitted
client = PiaClient(api_key="wi_live_your_key")

try:
    # 1. Fetch live multi-asset snapshot (105+ symbols)
    prices = client.market.get_prices()
    print(f"Total instruments tracked: {prices.total}")

    for item in prices.items[:5]:
        print(f"[{item.symbol}] ${item.price:.2f} (bid: {item.bid}, ask: {item.ask})")

    # 2. Fetch historical candlestick bars
    candles = client.market.get_candles("XAUUSD", timeframe="1h", limit=100)
    print(f"Fetched {candles.count} candles for {candles.symbol}")

    # 3. Check rate limit telemetry
    quota = client.get_rate_limit_info()
    print(f"Remaining daily requests: {quota.daily_remaining}/{quota.daily_limit}")

except AuthenticationError:
    print("Invalid or expired API key.")
except RateLimitError as e:
    print(f"Rate limited! Retry after {e.retry_after_seconds} seconds.")
except Exception as e:
    print(f"Unexpected error: {e}")
finally:
    client.close()

2. Asynchronous REST API (asyncio / FastAPI)

import asyncio
from pia import AsyncPiaClient

async def main():
    async with AsyncPiaClient(api_key="wi_live_...") as client:
        prices = await client.market.get_prices()
        print(f"Total instruments: {prices.total}")

asyncio.run(main())

3. Realtime WebSocket Streaming (In-Band Message Auth)

Cross-platform streaming without URL query-token leaks.

Asynchronous Streaming (Async Generator):

import asyncio
from pia import AsyncPiaClient

async def stream_prices():
    async with AsyncPiaClient(api_key="wi_live_...") as client:
        print("Connecting to live ticker feed...")
        async for tick in client.realtime.stream(["XAUUSD", "BTCUSDT"]):
            print(f"[TICK] {tick.symbol} -> ${tick.price:.2f} (bid: {tick.bid}, ask: {tick.ask})")

asyncio.run(stream_prices())

Synchronous / Callback-based (Background Thread):

from pia import PiaClient

client = PiaClient(api_key="wi_live_...")

# Register event callbacks
client.realtime.on("connect", lambda: print("WebSocket TCP connected."))
client.realtime.on("authenticated", lambda info: print("Authenticated successfully:", info))
client.realtime.on("tick", lambda tick: print(f"[TICK] {tick.symbol} -> {tick.price}"))
client.realtime.on("error", lambda err: print(f"Error: {err}"))

# Subscribe to target instruments
client.realtime.subscribe(["XAUUSD", "BTCUSDT"])

# Run in foreground (or call client.realtime.start() for non-blocking background thread)
client.realtime.run_forever()

Configuration Reference

from pia import PiaClient

client = PiaClient(
    # API key (defaults to os.environ["PIA_API_KEY"])
    api_key="wi_live_...",

    # Unified REST gateway (Default: "https://api-engine.wign.dev")
    base_url="https://api-engine.wign.dev",

    # Realtime WebSocket stream (Default: "wss://api-engine.wign.dev/api/v1/ws")
    ws_url="wss://api-engine.wign.dev/api/v1/ws",

    # Request timeout in seconds (Default: 15.0)
    timeout=10.0,

    # Maximum retry attempts on 5xx / 429 errors (Default: 3)
    max_retries=3,

    # Base retry delay for exponential backoff (Default: 0.5s)
    retry_delay=0.5,

    # Custom headers injected into all requests
    headers={"X-Trader-Id": "bot-algo-alpha"},

    # Enable debug logging (Default: False)
    debug=False,
)

Typed Exception Hierarchy

All exceptions thrown by the SDK inherit from PiaError:
