What can you build with Dimensions API?

Dimensions API is a Science API. Developers commonly use science APIs for:

accessing research datasets and scientific literature
powering academic and R&D applications
running scientific calculations and simulations
visualising experimental and observational data
integrating with research and reference databases

Bearer token. Your app exchanges credentials for a short-lived token, then sends it as an Authorization header. Tokens expire, so your code needs to handle renewal. Dimensions API is free to use up to a usage limit, making it a low-risk choice to experiment with.
