Data API

UK telecoms data, delivered straight into your systems

The Mastdata REST API gives you direct, programmatic access to UK mast locations, telecoms planning applications and real-world mobile signal survey data.

Every API is configured around the client — the data you need, the area you cover and the format your systems expect. Answer as many of the questions below as you can, and we will come back to you with a proposal.
