float-sdk 0.1.3

Float SDK: core API models and trading extensions

float-sdk

Python SDK for the Float platform. Provides typed domain models, API plumbing, and trading primitives used to build applications against Float services.

Installation

Requires Python 3.11+.

pip install float-sdk

From source:

pip install -e '.[dev]'

Quick start

Create a FloatClient (or FloatClientAsync for asyncio) using OAuth2 client credentials. The client manages authentication, token refresh, and HTTP transport for you.

import datetime as dt

from float_sdk import Environment, FloatClient
from float_sdk.float_api_trading.products.base.contractual import OptionType
from float_sdk.float_api_trading.products.fx.options import FXOptionModel
from float_sdk.float_api_trading.trading.parties import CounterpartyRole, PartyModel
from float_sdk.float_api_trading.trading.trades import TradeModel, TradeStatus, TradeType

with FloatClient(
    environment=Environment.PROD,
    client_id="...",
    client_secret="...",
) as client:
    trade = TradeModel(
        organization="org_123",
        trade_date=dt.date.today(),
        trade_time=dt.datetime.now(dt.UTC),
        trade_type=TradeType.EXECUTION,
        status=TradeStatus.LIVE,
        product=FXOptionModel(
            asset="EURUSD",
            notional_amount=1_000_000,
            notional_currency="EUR",
            option_type=OptionType.CALL,
            strike_price=1.20,
            expiration_date=dt.date.today() + dt.timedelta(days=30),
        ),
        party_1=PartyModel(entity="FOR8UP27PHTHYVLBNG30", role=CounterpartyRole.PARTY_1),
        party_2=PartyModel(entity="784F5XJDJFIQDTBV3E84", role=CounterpartyRole.PARTY_2),
    )

    created = client.trading.trades.create(trade)
    print(created.id)

Client structure

The client exposes resources as nested namespaces:

client.trading.trades   # /v1/trading/trades
client.trading.deals    # /v1/trading/deals

Each resource exposes the same lifecycle methods where supported by the API: create, get, list, update, delete (and cancel on trades).

Trades

created = client.trading.trades.create(trade)

trade = client.trading.trades.get(trade_id)

results = client.trading.trades.list(
    organization=["org_123"],
    type=[TradeType.EXECUTION],
    side=[CounterpartyRole.PARTY_2],
    limit=50,
    offset=0,
)
for t in results.results:
    ...
print(results.total_results, results.number_returned)

updated = client.trading.trades.update(trade)
client.trading.trades.delete(trade_id)
client.trading.trades.cancel(trade_id)

list() accepts ids, limit, offset, expand, type, deal, view, side, identifier, identifier_type, organization. See the docstring on TradesResource.list for the full reference.

Deals

deal = client.trading.deals.get(deal_id)

results = client.trading.deals.list(organization=["org_123"], limit=50)

Async client

FloatClientAsync mirrors FloatClient for asyncio code. Use it as an async context manager:

import asyncio

from float_sdk import Environment, FloatClientAsync


async def main() -> None:
    async with FloatClientAsync(
        environment=Environment.PROD,
        client_id="...",
        client_secret="...",
    ) as client:
        trade = await client.trading.trades.get("trade_123")
        print(trade.id)


asyncio.run(main())

Errors

All SDK errors derive from FloatError. HTTP responses are mapped to typed exceptions so callers can handle specific failure modes without inspecting status codes:

FloatError
└── APIError                    # has .detail, .request
    ├── APIConnectionError      # network failure
    │   └── APITimeoutError     # request timed out
    └── APIStatusError          # non-2xx response, has .response, .status_code
        ├── BadRequestError              # 400
        ├── AuthenticationError          # 401
        ├── PermissionDeniedError        # 403
        ├── NotFoundError                # 404
        ├── ConflictError                # 409
        ├── UnprocessableEntityError     # 422
        ├── RateLimitError               # 429
        └── InternalServerError          # 5xx

exc.detail is the human-readable string from the API's {"detail": ...} response. For 422 validation errors, the list of pydantic errors is flattened into a single field.path: msg; field.path: msg string. The full parsed body is still available via exc.response.json().

from float_sdk import FloatClient, NotFoundError, RateLimitError

with FloatClient(...) as client:
    try:
        trade = client.trading.trades.get("missing")
    except NotFoundError as exc:
        print(exc.detail)
    except RateLimitError as exc:
        print("backoff:", exc.response.headers.get("Retry-After"))

5xx responses (502/503) and timeouts are retried automatically with exponential backoff before being raised.
