const client = new OpenSink({
  apiKey: process.env.OPENSINK_API_KEY
});

// Create an item in your sink
await client.items.create("finance-news", {
  title: "AAPL dropped 3%",
  body: "Apple stock fell following earnings report",
  type: "alert",
  url: "https://example.com/news/aapl",
  fields: {
    ticker: "AAPL",
    change: -3,
    source: "bloomberg"
  }
});
