  title: 1Forge Forex Stream API
  version: '2024.01'
  description: |-
    1Forge streams real-time forex and cryptocurrency price updates over a single
    WebSocket connection at `wss://sockets.1forge.com/socket`. Messages are
    pipe-delimited text frames: `{action}|{body}`, where the body is either a single
    string token or a JSON document for `update` events.

    Clients must authenticate with their API key immediately after the socket opens
    and may subscribe to specific pairs, to all pairs, or unsubscribe at any time.
    WebSocket streaming is not available on free plans.
