RealMarketAPI Python SDK (Beta)

Official beta Python SDK for RealMarketAPI REST and WebSocket market data endpoints.

Website: https://realmarketapi.com/

Why use this SDK

• Thin Python wrapper for RealMarketAPI HTTP and streaming APIs.
• Simple class-based client for request/response usage.
• Async WebSocket streams with automatic reconnect behavior.
• Small dependency footprint (httpx, websockets).

Requirements

• Python 3.9+
• RealMarketAPI API key

Install

pip install realmarketapi-python-sdk-beta

Quick start

REST client

from realmarketapi_sdk import RealMarketApiClient

client = RealMarketApiClient(api_key="YOUR_API_KEY")

try:
    price = client.get_price("EURUSD", "M1")
    print("Close:", price.get("closePrice"))
finally:
    client.close()

WebSocket client

import asyncio
from realmarketapi_sdk import RealMarketApiWebSocket

ws = RealMarketApiWebSocket(api_key="YOUR_API_KEY")

async def main() -> None:
    async for tick in ws.stream_price("BTCUSDT", "M1"):
    print(tick)

asyncio.run(main())

REST API methods

All REST methods return a Python dict parsed from JSON and include your API key as query parameter.

get_price(symbol_code, time_frame)

Example:

price = client.get_price("EURUSD", "M1")

Example response payload:

{
    "symbolCode": "EURUSD",
    "timeFrame": "M1",
    "openPrice": 1.07874,
    "highPrice": 1.07882,
    "lowPrice": 1.07868,
    "closePrice": 1.07879,
    "openTime": "2026-05-21T09:12:00Z"
}

get_candles(symbol_code, time_frame)

Example:

candles = client.get_candles("BTCUSDT", "M5")

Example response payload:

{
    "symbolCode": "BTCUSDT",
    "timeFrame": "M5",
    "candles": [
        {
            "openTime": "2026-05-21T09:10:00Z",
            "openPrice": 68620.3,
            "highPrice": 68690.1,
            "lowPrice": 68588.7,
            "closePrice": 68655.8,
            "volume": 128.42
        }
    ]
}

get_history(symbol_code, start_time, end_time, page_number=1, page_size=20)

Example:

history = client.get_history(
    symbol_code="EURUSD",
    start_time="2026-05-20T00:00:00Z",
    end_time="2026-05-21T00:00:00Z",
    page_number=1,
    page_size=20,
)

Example response payload:

{
    "pageNumber": 1,
    "pageSize": 20,
    "totalPages": 14,
    "items": [
        {
            "openTime": "2026-05-20T00:00:00Z",
            "openPrice": 1.07913,
            "highPrice": 1.07942,
            "lowPrice": 1.07898,
            "closePrice": 1.07920,
            "volume": 241.11
        }
    ]
}

get_symbols()

Example:

symbols = client.get_symbols()

Example response payload:

{
    "symbols": ["EURUSD", "BTCUSDT", "XAUUSD"]
}

get_sma(symbol_code, time_frame, period=20)

Example:

sma = client.get_sma("EURUSD", "M15", period=50)

Example response payload:

{
    "symbolCode": "EURUSD",
    "timeFrame": "M15",
    "period": 50,
    "value": 1.08024,
    "openTime": "2026-05-21T09:00:00Z"
}

WebSocket streaming methods

The WebSocket client exposes async generators and reconnects after transient failures.

stream_price(symbol_code, time_frame)

Example:

async for event in ws.stream_price("EURUSD", "M1"):
    print(event)

Example message payload:

{
    "symbolCode": "EURUSD",
    "timeFrame": "M1",
    "closePrice": 1.07879,
    "openTime": "2026-05-21T09:12:00Z"
}

stream_candles(symbol_code, time_frame)

Example:

async for event in ws.stream_candles("BTCUSDT", "M5"):
    print(event)

Example message payload:

{
    "symbolCode": "BTCUSDT",
    "timeFrame": "M5",
    "openTime": "2026-05-21T09:10:00Z",
    "openPrice": 68620.3,
    "highPrice": 68690.1,
    "lowPrice": 68588.7,
    "closePrice": 68655.8,
    "volume": 128.42
}

Error handling notes

• REST methods call response.raise_for_status(), so HTTP 4xx/5xx responses raise httpx.HTTPStatusError.
• WebSocket streams retry on connection errors using reconnect_delay_seconds (default 2.0).
• Cancel the async task to stop streaming cleanly.

Beta scope and compatibility

• Current REST coverage: price, candles, history, symbols, SMA.
• Current WebSocket coverage: price and candles.
• This package is beta and may receive additive changes before stable 1.0.
