The Open Transport Initiative UK API provides 2 x different Open Standard API specifications for free usage since v1.0:
A standard way to facilitate peer-to-peer transport data sharing and account interoperability, allowing the customer to combine all their transportation, mobility and associated data in one place. Including: purchase, concession, and usage features in addition to operators, transactions, latitude and longitude, vehicle, and discount data.
A centralised look-up for all transport operators. This provides a transport directory service with unique reference information about each mode of transport or mobility organisation, including any publicly available Customer-account API URLs.
Both are made available on Swaggerhub for usage without conditions or fees.
The following is a list of sample source code snippets that matched your search term. Source code snippets are chunks of source code that were found out on the Web that you can cut and paste into your own source code. Whereas most of the sample source code we've curated for our directory is for consuming APIs, we occasionally find something interesting on the API provider side of things. If you know of some sample source code that would be of interest to the ProgrammableWeb community, we'd like to know about it. Be sure to check our guidelines for making contributions to ProgrammableWeb.
