Capabilities

Tools 8

best_time_to_ride

Cheapest time of day to take a ride. For New York, typical Uber and Lyft prices for a trip of a given length at every hour of the week, from the city's trip records, with the cheapest and most expensive hours today and whether waiting saves money. For other cities, how the taxi meter rates change by time of day.

Discovered
check_driver_licence

Check a New York taxi or ride-app driver's licence. Whether a TLC licence number is active on New York City's daily open data for for-hire (Uber, Lyft, car service) and taxi drivers, its expiry date, and, if a name is given, whether it matches (the name on the licence is never returned). Other cities get the official way to check.

Discovered
check_fare

Was I overcharged? Check a fare that was paid. Compares what was paid with the official meter tariff, the airport flat fare or New York's typical Uber and Lyft prices for the same trip and hour, gives a verdict (fair, high or overcharged), the next steps for that company or city regulator, and a short message to send asking for a refund.

Discovered
check_fleet_file

Check a cab firm's fleet.json. Reads a taxi or minicab firm's fleet.json (the open format at fairfare.pages.dev/fleet that lets assistants find and book local firms directly) and lists anything to fix.

Discovered
estimate_fare

What a trip should cost by taxi, Uber or Lyft. Distance and time by road between two places, the licensed taxi meter fare with the extras that apply at that hour, any airport flat fare, typical Uber and Lyft prices in New York, airport pickup rules, a pre-booked transfer option for airport trips, and links that open Uber, Lyft or public transport directions with the trip filled in.

Discovered
get_airport

Getting a ride at an airport. Where Uber and Lyft pick up, how the taxi rank works, flat taxi fares, drop-off and pickup charges for cars, meet and greet rules, public transport into the city with prices, and tips, from each airport's own pages.

Discovered
get_taxi_tariff

A city's official taxi meter tariff. The starting charge, the rate per mile or kilometre, the waiting rate, time-of-day tariffs, extras and surcharges, flat fares, tipping custom and the official source.

Discovered
list_cities

Cities and airports covered. Every city whose official taxi tariff is on file and every airport with ground transport facts.
