Transport for LondonUsing the feeds
Developer guidelines
When using Transport for London's (TfL) syndicated feeds it is important that you follow the Syndication Developer Guidelines.
The guidelines include technical information to help developers understand how the feeds work and how to implement them correctly according to the terms and conditions.
TfL developer content is provided free of charge, however you must not charge the public - directly or indirectly - for accessing the information contained in the feeds.
Information on data refresh rates and presentation, including important TfL branding requirements, is also provided in the guidelines.

Requirements
IP access requirements (applicable to all feeds)
Only one IP address should be used to access any of the feeds within a 12 hour period, thereby allowing access by account holders not on a fixed IP. The feeds should only be accessed by the account holder, using the Syndicated feed URL provided to them. The account holder is thereafter responsible for the distribution of their copy of the feed.
