Rest API for getting attribute option information

I want to get a list of all attributes.

I know that domain.com/rest/V1/products/attributes/{{ATTRIBUTE_ID}}/options will grab an the attribute options, but how do i get a list of all attributes so I can know what all of the attribute_ids are?

(I don’t really want to grab by attribute-set, I want all eav attributes, including all attributes that are not product attributes).

Edit:
/rest/V1/products/attributes/?searchCriteria gets me close

Edit2:
A quick look at /Magento/Eave/etc/webapi.xml is leaving me thinking this is not something that can be done out of the box.
