Biostrap users can access and export their data from our web dashboard: https://app.biostrap.com
Developers can access API documentation here: https://biostrap.link/apiv1
We have a REST API and the data output is in JSON.
Right now, users can only access the values presented in the app itself and not the raw waveform data.
Unfortunately, we are unable to share raw waveform data this at this time.
In regards to an SDK, we currently do not have one available, but with enough interest may consider in the long term.
