Chainlink Tiingo External Adapter

Environment Variables

Required?	Name	Description	Options	Defaults to
✅	API_KEY	An API key that can be obtained from here

Websocket support

This adapter has Websocket support. However, the Tiingo WS API only offers price updates from individual exchanges with no aggregation. Because of this, Tiingo WS should not be used to provide data to the Chainlink price feeds. To avoid node operators accidentally running this with WS enabled, WS will only be enabled when run in development mode. To enable WS, set NODE_ENV=development in addition to WS_ENABLED=true.
