Quick Start

Get Market Information

import asyncio
from pacifica_sdk.async_.info import Info

async def main():
    info = Info()
    markets = await info.get_market_info()
    for market in markets:
        print(market.symbol, market.max_leverage)
    await info.close()

asyncio.run(main())

Create a Limit Order

import asyncio
from pacifica_sdk.async_.exchange import Exchange
from pacifica_sdk.models.requests import CreateLimitOrder, Side, TIF

PRIVATE_KEY = "YOUR_PRIVATE_KEY"

async def main():
    exchange = Exchange(private_key=PRIVATE_KEY)
    order = CreateLimitOrder(
        symbol="BTCUSDT",
        price="30000",
        amount="0.01",
        side=Side.BID,
        tif=TIF.GTC,
    )
    response = await exchange.create_order(order)
    print("Order ID:", response.data.order_id)
    await exchange.close()

asyncio.run(main())

Subscribe to Price Stream via WebSocket

import asyncio
from pacifica_sdk.async_.websocket_manager import WebsocketManager
from pacifica_sdk.models.ws_subscribe import WSPricesSubscribe

async def on_prices_update(data):
    print("Prices update:", data)

async def main():
    ws_manager = WebsocketManager()
    params = WSPricesSubscribe()
    await ws_manager.subscribe(params, on_prices_update)
    await asyncio.sleep(60)
    await ws_manager.close()

asyncio.run(main())

---

Error Handling

The SDK raises custom exceptions:

• ApiError — for API errors (4xx)
• ServerError — for server errors (5xx)

from pacifica_sdk.utils.error import ApiError, ServerError

try:
    # Your code here
    ...
except ApiError as e:
    print("API error:", e)
except ServerError as e:
    print("Server error:", e)

---

Package Structure

• pacifica_sdk.async_ — asynchronous clients (API, Exchange, Info, WebSocket)
• pacifica_sdk.models — Pydantic models for requests, responses, and streams
• pacifica_sdk.utils — utilities, error handling, message signing
• pacifica_sdk.enums — enums for statuses, order types, etc.
• pacifica_sdk.constants — constants (URLs, etc.)

---

Documentation

• API Reference
• WebSocket Reference

Roadmap / Upcoming Features

The following features are planned for future releases:

• Trading operations via WebSocket:
  Place, modify, and cancel orders in real time using the WebSocket API.

• Comprehensive docstrings:
  All public classes and functions will include detailed docstrings for better developer experience and IDE support.

• More usage examples:
  The documentation and repository will include more practical code samples for common SDK use cases.

• Price and order size rounding utilities:
  Helper functions for correct rounding of prices and order sizes according to market requirements.

• Synchronous client:
  (Planned) Support for synchronous (non-async) usage for simpler integration in legacy projects.

• Extensive test coverage:
  More unit and integration tests to ensure reliability and stability.

• Type hints and static analysis improvements:
  Even stricter type checking and mypy compatibility.

• Logging in all modules:
  Consistent and configurable logging will be added across all SDK modules for better debugging and monitoring.
