Pyth Price Feeds

Fetch real-time price data from Pyth Network oracles

Fetch real-time price data from Pyth Network’s decentralized oracle network. Access price feeds for various crypto assets with support for symbol lookup and price formatting.

1. Price Feed Management

   • Symbol-based feed lookup

   • Price feed ID resolution

   • Real-time price fetching

   • Decimal adjustment

2. Price Operations

   • Multi-symbol support

   • Price scaling

   • Error handling

   • Format conversion

Copy

// Get feed ID by token symbol
const feedId = await agent.methods.getPythPriceFeedID("SOL");
console.log("SOL Price Feed ID:", feedId);

Copy

// Fetch current price using feed ID
const price = await agent.methods.getPythPrice(feedId);
console.log("Current Price:", price);

// Or chain the operations
const symbol = "SOL";
const feedId = await agent.methods.getPythPriceFeedID(symbol);
const price = await agent.methods.getPythPrice(feedId);

Copy

"Get the current SOL price from Pyth"

"Check ETH price using Pyth oracle"

"Fetch BTC/USD price feed"

"Look up price feed ID for USDC"

• Most feeds update every 400ms

• Updates depend on market conditions

• Consider confidence intervals

• Monitor update timestamps

1. Price Monitoring

   Copy

   // Regular price checks
   setInterval(async () => {
     const price = await agent.methods.getPythPrice(feedId);
     console.log(`Current price: $${price}`);
   }, 5000);

2. Error Recovery

   Copy

   async function getPriceWithRetry(feedId: string, retries = 3) {
     for (let i = 0; i < retries; i++) {
       try {
         return await agent.methods.getPythPrice(feedId);
       } catch (error) {
         if (i === retries - 1) throw error;
         await new Promise(r => setTimeout(r, 1000));
       }
     }
   }
