📦 Installation

pip install OpenF1-python-client

Or install from source:

git clone https://github.com/rhtnr/OpenF1-python-client.git
cd OpenF1-python-client
pip install -e .

For development:

pip install -e ".[dev]"

🚀 Quick Start

Basic Usage (Unauthenticated)

Historical data is available without authentication:

from openf1_client import OpenF1Client

# Create a client
client = OpenF1Client()

# Get lap data for a specific driver
laps = client.laps.list(
    session_key=9161,
    driver_number=63,
)

for lap in laps:
    print(f"Lap {lap.lap_number}: {lap.lap_duration}s")

# Don't forget to close the client when done
client.close()

Using Context Manager

from openf1_client import OpenF1Client

with OpenF1Client() as client:
    # Get driver information
    drivers = client.drivers.list(session_key=9158)

    for driver in drivers:
        print(f"{driver.name_acronym}: {driver.full_name} - {driver.team_name}")

🔐 Authenticated Usage

For real-time data and higher rate limits, authenticate with your OpenF1 credentials:

from openf1_client import OpenF1Client

client = OpenF1Client(
    username="your_email@example.com",
    password="your_password",
)

# Access real-time data
latest_session = client.sessions.first(session_key="latest")
print(f"Current session: {latest_session.session_name}")

Or use a pre-existing access token:

client = OpenF1Client(access_token="your_access_token")

🔍 Filtering Data

OpenF1 supports rich filtering with comparison operators. The client provides a Pythonic interface:

Simple Equality

# Filter by exact values
laps = client.laps.list(
    session_key=9161,
    driver_number=63,
    lap_number=8,
)

Comparison Operators

Use dictionaries with operator keys for comparisons:

# Speed >= 315 km/h
fast_telemetry = client.car_data.list(
    session_key=9159,
    driver_number=55,
    speed={">=": 315},
)

# Close intervals (< 0.5 seconds)
close_battles = client.intervals.list(
    session_key=9161,
    interval={"<": 0.5},
)

Range Filters

# Date range
location_data = client.location.list(
    session_key=9161,
    driver_number=81,
    date={
        ">": "2023-09-16T13:03:35.200",
        "<": "2023-09-16T13:03:35.800",
    },
)

# Lap range
stint_laps = client.laps.list(
    session_key=9161,
    driver_number=1,
    lap_number={">=": 10, "<=": 20},
)

Using FilterBuilder

For more complex filters, use the FilterBuilder helper:

from openf1_client import OpenF1Client, FilterBuilder

with OpenF1Client() as client:
    filters = (
        FilterBuilder()
        .eq("session_key", 9161)
        .eq("driver_number", 1)
        .gte("speed", 300)
        .lt("lap_number", 10)
        .build()
    )

    car_data = client.car_data.list(**filters)

📡 Available Endpoints

🛠️ Endpoint Methods

Each endpoint provides several methods:

# List all matching records
laps = client.laps.list(session_key=9161, driver_number=1)

# Get first matching record (or None)
lap = client.laps.first(session_key=9161, driver_number=1, lap_number=1)

# Get raw data (dict) without model parsing
raw_data = client.laps.list_raw(session_key=9161)

# Get CSV format
csv_data = client.laps.list_csv(session_key=9161)

# Count matching records
count = client.laps.count(session_key=9161, driver_number=1)

Many endpoints also provide convenience methods:

# 🔄 Laps
fastest_lap = client.laps.get_fastest_lap(session_key=9161)
flying_laps = client.laps.get_flying_laps(session_key=9161, driver_number=1)

# 📅 Sessions
races = client.sessions.get_races(year=2023)
latest = client.sessions.get_latest()

# 🔧 Stints
strategy = client.stints.get_tyre_strategy(session_key=9161, driver_number=1)

# 🌤️ Weather
rain = client.weather.get_rain_periods(session_key=9161)

⚙️ Configuration

from openf1_client import OpenF1Client

client = OpenF1Client(
    # 🔐 Authentication
    username="user@example.com",
    password="secret",
    # Or use a token directly
    # access_token="your_token",

    # 🌐 Connection settings
    timeout=60.0,                    # Request timeout in seconds
    # timeout=(5.0, 30.0),           # (connect, read) timeouts
    max_retries=5,                   # Retry failed requests

    # 📄 Response format
    default_format="json",           # "json" or "csv"

    # 🔒 SSL/TLS
    verify_ssl=True,
)

⚠️ Error Handling

The client provides a comprehensive exception hierarchy:

from openf1_client import (
    OpenF1Client,
    OpenF1Error,           # Base exception
    OpenF1ConfigError,     # Invalid configuration
    OpenF1TransportError,  # Network errors
    OpenF1APIError,        # API errors (non-2xx)
    OpenF1AuthError,       # 401/403 errors
    OpenF1RateLimitError,  # 429 errors
    OpenF1NotFoundError,   # 404 errors
    OpenF1ServerError,     # 5xx errors
    OpenF1TimeoutError,    # Request timeout
    OpenF1ValidationError, # Data validation
)

try:
    with OpenF1Client() as client:
        laps = client.laps.list(session_key=99999)
except OpenF1NotFoundError as e:
    print(f"❌ Session not found: {e}")
except OpenF1RateLimitError as e:
    print(f"⏳ Rate limited. Retry after: {e.retry_after}s")
except OpenF1APIError as e:
    print(f"⚠️ API error {e.status_code}: {e.message}")
except OpenF1Error as e:
    print(f"💥 Client error: {e}")

📝 Logging

Enable debug logging to see HTTP requests and responses:

from openf1_client import setup_logging
import logging

# Enable debug logging
setup_logging(logging.DEBUG)

# Or configure manually
logging.basicConfig(level=logging.DEBUG)
logger = logging.getLogger("openf1_client")
logger.setLevel(logging.DEBUG)

📊 Data Models

All responses are parsed into Pydantic models with full type annotations:

from openf1_client import OpenF1Client, Lap, Driver

with OpenF1Client() as client:
    lap: Lap = client.laps.first(session_key=9161, driver_number=1, lap_number=1)

    if lap:
        print(f"Lap duration: {lap.lap_duration}")
        print(f"Sector 1: {lap.duration_sector_1}")
        print(f"Sector 2: {lap.duration_sector_2}")
        print(f"Sector 3: {lap.duration_sector_3}")
        print(f"Speed trap: {lap.st_speed} km/h")

🔮 Future Enhancements

The client is designed to be easily extended. Planned additions:

⚡ Async Support

# Future async client (design ready, not yet implemented)
from openf1_client import AsyncOpenF1Client

async with AsyncOpenF1Client() as client:
    laps = await client.laps.list(session_key=9161)

📡 Real-time Streaming

# Future streaming support (design ready)
# Via MQTT or WebSockets for live data
async for telemetry in client.car_data.stream(driver_number=1):
    print(f"🏎️ Speed: {telemetry.speed} km/h")
