notes: >-
  Duckbill has no public REST OpenAPI to derive from. Its programmatic surface
  (the "Connect to Claude" MCP integration and platform/API access) authenticates
  through an OAuth 2.0 / OpenID Connect authorization server hosted by Clerk on
  Duckbill's own subdomain clerk.getduckbill.com. End-user app auth is also Clerk.
