Is there an API reference documentation to access Helios data?

Hi there,

I am new to Helios, I was able to follow the setup for Node.JS on a test service and I am able to see different traces on the visualizer.

Is there a way I can pull traces from my service programmatically? And get a JSON representation of them as a response?

At large, is there a API reference documented for the underlying calls done by the SDks? For instance, is there an Open API/Swagger specification for Helios endpoints?

I tried accessing
GET https://collector.heliosphere.io/traces
Authorization: {My_Helios_Token}
but this didn't work

But I am wondering if there is also an endpoint for pulling, services, environments, my account details ("/me") and so on.
