    plantPredictOAuth:
      type: oauth2
      description: >-
        The upstream spec advertises only a bearer scheme, but the API description documents an OAuth 2.0 client
        credentials exchange against AWS Cognito. Declared here so generated clients can perform the token exchange.
      flows:
        clientCredentials:
          tokenUrl: https://terabase-prd.auth.us-west-2.amazoncognito.com/oauth2/token
          scopes:
            transactions/get: Read access to the PlantPredict API surface.
            transactions/post: Write access to the PlantPredict API surface.
