Ask HN: Health insurance APIs?

Does anyone know of APIs for the following usecases:

- Get a list of insurance providers.

- Get a member's plan details. Given an insurance provider, member ID, and potentially other info.

- Get a member's paid deductible and out-of-pockets from claims. Given an insurance provider, member ID, and potentially other info.

- Get eligibility or pricing info for a procedure or doctor. Given an insurance provider, member ID, doctor identification, and potentially other info like procedure codes.

I'm working on making this type of information more accessible for developers, and hoping to build a few example apps. However, I'm having trouble finding these types of services. Any help would be much appreciated!
