WS accountSubscribe

With @solana/web3.js

const id = rpc.onAccountChange(new PublicKey("<ADDRESS>"), (acc, ctx) => console.log(ctx.slot, acc.lamports));

The interactive runner covers HTTP methods. WebSocket subscriptions use a persistent socket — use the subscribe message and the @solana/web3.js example above.
