ukfuelfinder 1.0.0

Python library for accessing the UK Government Fuel Finder API

UK Fuel Finder Python Library

Python library for accessing the UK Government Fuel Finder API.

Features

• OAuth 2.0 Authentication - Automatic token management with refresh support
• Comprehensive Data Access - Fuel prices and forecourt information
• Built-in Caching - Reduces API calls with configurable TTL
• Rate Limiting - Automatic retry with exponential backoff
• Type Hints - Full type annotations for better IDE support
• Extensive Error Handling - Clear exceptions for all error cases
• Batch Pagination - Automatic handling of 500-record batches
• Incremental Updates - Fetch only changed data since a specific date

Installation

pip install ukfuelfinder

Quick Start

from ukfuelfinder import FuelFinderClient

# Initialize client
client = FuelFinderClient(
    client_id="your_client_id",
    client_secret="your_client_secret",
    environment="production"  # or "test"
)

# Get all fuel prices
prices = client.get_all_pfs_prices()

# Search for stations near a location (returns list of (distance, PFSInfo) tuples)
nearby = client.search_by_location(latitude=51.5074, longitude=-0.1278, radius_km=5.0)
for distance, station in nearby:
    print(f"{distance:.2f}km - {station.trading_name}")

# Get prices for specific fuel type
unleaded_prices = client.get_prices_by_fuel_type("unleaded")

# Get forecourt information
forecourts = client.get_all_pfs_info()

# Get incremental updates since yesterday
from datetime import datetime, timedelta
yesterday = (datetime.now() - timedelta(days=1)).strftime("%Y-%m-%d")
updated_prices = client.get_incremental_price_updates(yesterday)

Environment Variables

Set credentials via environment variables:

export FUEL_FINDER_CLIENT_ID="your_client_id"
export FUEL_FINDER_CLIENT_SECRET="your_client_secret"
export FUEL_FINDER_ENVIRONMENT="production"

Then initialize without parameters:

client = FuelFinderClient()

Future Enhancements

Potential features for future development:

Smart Fuel Recommendations

• Cost-optimized routing - Calculate total fuel cost including detour distance based on vehicle consumption
• Cheapest fuel finder - Find the most economical option considering current location, fuel prices, and distance
• Route integration - Suggest fuel stops along planned routes with minimal detour

Price Intelligence

• Price alerts - Notify users when prices drop below a threshold in their area
• Price forecasting - Predict price trends based on historical data
• Price comparison - Compare prices across brands, regions, and fuel types

Advanced Filtering

• Multi-criteria search - Filter by amenities (car wash, shop, 24-hour, EV charging)
• Brand preferences - Filter by preferred fuel brands or loyalty programs
• Fuel type availability - Find stations with specific fuel types (HVO, E10, premium diesel)

Journey Planning

• Fuel range calculator - Estimate remaining range and suggest refuel points
• Multi-stop optimization - Plan optimal fuel stops for long journeys
• Emergency fuel finder - Quick search for nearest station when running low

Data Analytics

• Spending tracking - Monitor fuel expenses over time
• Savings calculator - Calculate savings from using cheapest stations
• Regional price analysis - Compare average prices across different areas

Integration Features

• Navigation app integration - Direct routing to selected stations
• Calendar integration - Schedule reminders for regular refueling
• Vehicle integration - Sync with vehicle telematics for automatic consumption data
