📝 Usage

Example of bitFlyer API:

HTTP API

New interface from version 1.0: Fetch API.

More simple request/response.

import asyncio

import pybotters

apis = {
    "bitflyer": ["YOUER_BITFLYER_API_KEY", "YOUER_BITFLYER_API_SECRET"],
}


async def main():
    async with pybotters.Client(
        apis=apis, base_url="https://api.bitflyer.com"
    ) as client:
        # Fetch balance
        r = await client.fetch("GET", "/v1/me/getbalance")

        print(r.response.status, r.response.reason, r.response.url)
        print(r.data)

        # Create order
        CREATE_ORDER = False  # Set to `True` if you are trying to create an order.
        if CREATE_ORDER:
            r = await client.fetch(
                "POST",
                "/v1/me/sendchildorder",
                data={
                    "product_code": "BTC_JPY",
                    "child_order_type": "MARKET",
                    "side": "BUY",
                    "size": 0.001,
                },
            )

            print(r.response.status, r.response.reason, r.response.url)
            print(r.data)


asyncio.run(main())

aiohttp-based API.

    "bitflyer": ["YOUER_BITFLYER_API_KEY", "YOUER_BITFLYER_API_SECRET"],
}


async def main():

        async with client.get("/v1/me/getbalance") as resp:
            data = await resp.json()

        print(resp.status, resp.reason)
        print(data)

        # Create order
        CREATE_ORDER = False  # Set to `True` if you are trying to create an order.
        if CREATE_ORDER:
            async with client.post(
                "/v1/me/sendchildorder",
                data={
                    "product_code": "BTC_JPY",
                    "child_order_type": "MARKET",
                    "side": "BUY",
                    "size": 0.001,
                },
            ) as resp:
                data = await resp.json()

            print(data)

WebSocket API

import asyncio

        wsqueue = pybotters.WebSocketQueue()

        await client.ws_connect(

            },
            hdlr_json=wsqueue.onmessage,
        )

        # Iterate message (Ctrl+C to break)
        async for msg in wsqueue:
            print(msg)


try:
    asyncio.run(main())
except KeyboardInterrupt:
    pass

DataStore

import asyncio

        store = pybotters.bitFlyerDataStore()
