Making data available to developers using APIs

Application programing interfaces (APIs) underpin common actions such as posting on social media or buying a concert ticket online— they are key to bridging the gap between legacy applications and innovative digital solutions.

APIs enable Chief Information Officers (CIOs) and Chief Digital Officers (CDOs) to develop a strategy that enables application modernisation and reduces the friction between legacy and modern systems.

We have already used APIs to help our clients to:

  • Catalogue their application portfolio
  • Optimise assets like data and transactions
  • Address problems such as skills gaps or legacy integration

A UK government department has a back-end tidal protection system, built using accurate and reliable data from the UK’s largest network of tidal stations. They need to make this prediction capability available as an API to developers across the UK using a subscription (paid and free) model.
