summary: >-
  Numerai supports outbound webhooks for Compute / Prediction Nodes. A user registers a webhook URL
  for a model; Numerai invokes that URL each round so the user's cloud node computes and uploads a
  submission automatically. There is no inbound event-subscription (AsyncAPI) surface — the direction
  is Numerai -> user compute node.
