IOMED Medical Language API

If you are working with clinical data, you may have notice that a staggering amount of it is stored as text. The time will come when you need to extract insights from it and... where to start?

IOMED's Medical Language API is a simple API allowing organizations, developers and researchers to extract and codify medical concepts from unstructured medical text in Spanish.


Currently we support Spanish, with limited support for Catalan. If you would like to use this API in some other language, we would be interested in hearing it. Please let us know sending an email to


This API allows you to easily extract medical concepts from unstructured text, allowing you to either analyze existing medical text, or build applications that automatically recognize medical concepts. Some common use cases are:

  • Dark data extraction
    • Analytics on medication, symptoms, diseases, procedures…
    • Monitoring
  • Conversational interfaces
