モデル¶
各エンドポイントは生の辞書ではなく Pydantic モデルを返します。そのためフィールドは
検証済みで、日時は datetime として受け取れ、エディタの補完も効きます。すべて
パッケージのルートからインポートできます:
product_code や side、child_order_state などのフィールドは、意図的に enum では
なく str として定義しています。bitFlyer は予告なく銘柄や状態値を追加するため、
閉じた enum にすると正当なレスポンスを弾いてしまうからです。既知の値は
Enums を参照してください。
なお、以下の説明文（docstring）は英語で記述されています。
Public API¶
Response models for the Public API.
String fields such as product_code, state and side are typed str
rather than as enums so that a product or state bitFlyer adds after this release
still parses. See pylightningfx.enums for the known values.
Bases: BaseModel
A tradable market.
Bases: BaseModel
A snapshot of the order book.
The order of bids and asks is not guaranteed, so sort before
treating the first element as the best price::
best_bid = max(board.bids, key=lambda e: e.price)
Bases: BaseModel
Best bid and ask, last traded price, and rolling volume.
instance-attribute
¶
24-hour volume across every market of the underlying asset.
instance-attribute
¶
24-hour volume for this product_code alone.
class-attribute
instance-attribute
¶
When the pre-open auction ends. Undocumented by bitFlyer; usually None.
class-attribute
instance-attribute
¶
When the circuit breaker lifts. Undocumented by bitFlyer; usually None.
Bases: BaseModel
Exchange health for one market.
Bases: BaseModel
Maximum leverage for corporate accounts, current and upcoming.
Private API¶
Request and response models for the Private API.
String fields such as product_code, side and child_order_state are
typed str rather than as enums so that a value bitFlyer adds after this
release still parses. See pylightningfx.enums for the known values.
Bases: BaseModel
An incoming crypto transfer.
Bases: BaseModel
An outgoing crypto transfer.
Bases: BaseModel
A registered bank account, usable as a withdrawal destination.
Bases: BaseModel
A cash withdrawal.
Bases: BaseModel
Acknowledgement of a withdrawal request.
instance-attribute
¶
Pass as message_id to get_withdrawals to follow up on this request.
Bases: BaseModel
Acknowledgement of an order submission.
The exchange has accepted the order, not necessarily filled or even placed
it. Poll get_child_orders with the acceptance id, or subscribe to
child_order_events on the Realtime API, to learn what happened.
Bases: BaseModel
Acknowledgement of a parent order submission.
Bases: BaseModel
One of your orders.
Bases: BaseModel
One of your parent (conditional) orders, as listed.
Bases: BaseModel
One leg of a parent order.
Serves as both the input to send_parent_order and an element of
parameters. Fields that only
apply to certain
condition types default to None and are left out of the request body::
client.send_parent_order(
[
ParentOrderParameter(
product_code=ProductCode.FX_BTC_JPY,
condition_type=ConditionType.STOP,
side=Side.SELL,
size=0.01,
trigger_price=9_000_000,
)
]
)
Bases: BaseModel
A parent order together with its legs.
Bases: BaseModel
One of your fills.
Bases: BaseModel
One entry from the balance ledger.
Bases: BaseModel
An open leveraged position.
bitFlyer reports positions individually rather than netted, so a single market can hold several entries on the same side.
instance-attribute
¶
Swap For Difference charge, applied when FX_BTC_JPY diverges from BTC_JPY.
Bases: BaseModel
One change to the collateral balance.
Realtime API¶
配信チャンネルのうち公開系は上記のモデルをそのまま再利用します。専用のモデルを 持つのは、自分の注文イベントを流すプライベートチャンネルだけです。
Models for the private Realtime API channels.
The public channels reuse the Public API models: lightning_board* delivers a
Board, lightning_ticker_* a
Ticker, and lightning_executions_* a list of
Execution.
Most fields below are optional because bitFlyer sends a different subset per
event_type; each one documents when it is present.
Bases: BaseModel
One lifecycle event for one of your orders.
Delivered on the child_order_events channel. Watch event_type to
decide which optional fields to read; see
ChildOrderEventType.

COMPLETE instead of CANCEL_FAILED and EXECUTION.
