"I'm trying to use the BreezeDocs API on my Agency account. When I call https://breezedoc.com/api/v1/documents with a valid Personal Access Token, I get an HTML 404 page instead of a JSON response. The API documentation shows this endpoint should exist. Can you confirm: (1) Is the API enabled on my account? (2) Is this the correct endpoint URL? (3) Are there any special setup steps needed for Agency accounts?"
