### Request Pyth Price Updates via HTTP

Source: https://github.com/pyth-network/pyth-client-js/blob/main/README.md

Fetches all Pyth product data, including current prices and metadata, using an HTTP request. It iterates through symbols and logs price details.

```typescript
const pythClient = new PythHttpClient(connection, pythPublicKey);
const data = await pythClient.getData();

for (let symbol of data.symbols) {
  const price = data.productPrice.get(symbol)!
  // Sample output:
  // Crypto.SRM/USD: $8.68725 ±$0.0131 Status: Trading
  console.log(`${symbol}: $${price.price} \xB1$${price.confidence} Status: ${PriceStatus[price.status]}`) 
}
```

--------------------------------

### Stream Pyth Price Updates via WebSocket

Source: https://github.com/pyth-network/pyth-client-js/blob/main/README.md

Establishes a WebSocket connection to Pythnet to receive real-time price updates. It uses `PythConnection` and `onPriceChange` to log symbol, price, confidence, and status.

```typescript
const pythConnection = new PythConnection(pythnetWeb3Connection, getPythProgramKeyForCluster(pythnetClusterName))
pythConnection.onPriceChange((product, price) => {
  // sample output:
  // Crypto.SRM/USD: $8.68725 ±$0.0131 Status: Trading
  console.log(`${product.symbol}: $${price.price} \xB1$${price.confidence} Status: ${PriceStatus[price.status]}`)
})

// Start listening for price change events.
pythConnection.start()
```
