Yourtaximeter is a free online service that calculates taxi fares in the UK. Calculations account for local rates, date, time, passengers, and surcharges. The yourtaximeter API allows 3rd party applications and websites to instantly calculate fares as well as lookup car license plates and confirm that a vehicle is a licensed taxi. The API requires an API Key and returns XML or JSON formatted responses.
How much will it cost to hire that cabbie? The Yourtaximeter API gives access to such precise data that cab companies in the UK rely on it to give quotes. Yourtaximeter provides a tool anyone can use to calculate a fare. The API documentation, other than providing a link to where you can get an access key and noting responses are flexibly delivered in JSON or XML, is rather skimpy. That's actually a complement: minimal documentation reflects the fact that no coding skills are required.
