note: >-
  The Sequence Indexer is the provider's event surface. It supports registered HTTP
  webhook listeners (delivered to a consumer callback URL) and server-push subscription
  streams. No standalone AsyncAPI document is published by Sequence, so this captures the
  webhook/subscription catalog derived from the Indexer webrpc spec. NOT fabricated.
transport:
  webhooks: HTTP POST to a consumer-registered callback URL, managed via Indexer webrpc ops
  streams: server-push subscriptions over the webrpc connection
