Hey @glenwickert,
Good distinction between the collection download and a direct download to the API spec. We’re actually going to make the spec available soon, in fact you can see it now if you’d like at GitHub - sailpoint-oss/api-specs: This repo houses the API specifications for all SailPoint services..
I will warn you, though, that it is not dereferenced and would require something like swagger-cli to dereference it. We plan on making other tools typically based off of the OpenAPI reference directly available, open source, and supported by SailPoint (like a Postman workspace and SDKs, for example).
I’m curious, what do you typically use the OpenAPI spec for?
