description: >-
  ETHGas exposes a realtime push surface over WebSocket rather than HTTP
  webhooks. Clients connect, then use the subscribe/unsubscribe/query/login
  commands to stream public market data and (after login) private account
  events. Captured as a channel catalog; ETHGas publishes no AsyncAPI document.
