Openapi Generator Authentication

description: >-
  Authentication profile for the hosted OpenAPI Generator Online API. The result
  is an honest zero: the service is anonymous and open. derive-authentication.py
  produced no profile because the Swagger 2.0 document declares no
  securityDefinitions block at all, and a live unauthenticated GET returned 200,
  confirming that this is genuinely an open API rather than a spec that merely
  omits its scheme.

declared_error_codes_note: >-
  Every operation declares 401 Unauthorized and 403 Forbidden. These are Spring
  Boot framework defaults enumerated by the springfox/springdoc generator, not
  evidence of an auth layer — no scheme exists to produce them.
inbound_credentials_note: >-
  The GeneratorInput request body carries an optional `authorizationValue`
  object (keyName / type / value / urlMatcher). That credential is not for
  authenticating to this API — it is passed THROUGH so the generator can fetch a
  protected `openAPIUrl` on the caller's behalf. Callers should treat this as
  sending a third-party secret to a public unauthenticated service over the open
  internet, and prefer the CLI (cli/openapi-generator-cli.yml) for any spec that
  requires credentials to retrieve.
