The CTB's open data portal is a service aimed at publishing data relating to public transport in the area of Biscay.

The purpose of this portal is to compile and publish information relating to different aspects of public transport in Biscay and interoperability, where appropriate, with other territories, in: service offerings, fare systems, customer service offices, etc.

These data are available on this portal in standard, open and known formats, and can be downloaded and/or consulted automatically through a data API.
