  version: '1.0'
  description: |
    Realtime subscription stream for the Tensor Solana NFT marketplace. Clients open a
    single WebSocket connection authenticated with `x-tensor-api-key`, then send JSON
    subscribe/unsubscribe control frames addressing one of the channels below. The
    server publishes JSON event frames as marketplace state changes on-chain.

    Documented at https://dev.tensor.trade/reference.
