  Authentication profile for the Apache PredictionIO Event Server REST API. The
  Event Server authenticates requests with a per-app access key. Engine query
  endpoints are unauthenticated by default and rely on network-level controls.
docs: https://predictionio.apache.org/datacollection/eventapi/
schemes:
- id: accessKey
  type: apiKey
  in: query
  name: accessKey
  applies_to: Event Server API (localhost:7070)
  description: >-
    Per-application access key passed as the `accessKey` query parameter on every
    Event Server request. Generated when an app is created via the CLI command
    `pio app new`. Example: /events.json?accessKey=yourAccessKeyString
- id: none
  type: none
  applies_to: Engine Query API (localhost:8000)
  description: >-
    The deployed prediction engine query endpoint (POST /queries.json) has no
    built-in authentication; access is expected to be restricted at the network
    or gateway layer.
notes: >-
  No OAuth2, OpenID Connect, or mutual TLS is documented. The access key is an
  opaque application credential, not an OAuth token, so no scopes apply.
