Price Object Fields

Field	Type	Description
id	string	Pyth hex feed ID
price.price	string	Raw price integer
price.conf	string	Confidence interval (always "0" from proxy)
price.expo	number	Exponent (e.g., -8). Actual price = price * 10^expo
price.publish_time	number	Unix timestamp (seconds)
ema_price	object	Exponential moving average (same format as price)
blend	object	Blend metadata (present when blending is active)

Blend Fields

Field	Type	Description
token	string	Token contract address
pythPrice	string	Pyth oracle price in WAD
cexPrice	string	CEX reference price in WAD
blendFactor	string	Blend ratio in WAD (0 = Pyth, 1e18 = CEX)
blendedPrice	string	Final execution price in WAD

Example: Seed Prices Before SSE

// Fetch once on page load, then switch to SSE for live updates
async function seedPrices(feedIds) {
  const params = feedIds.map(id => `ids[]=${id}`).join('&');
  const res = await fetch(
    `https://mainnet.proxy.ryze.pro/v2/updates/price/latest?${params}`
  );
  const data = await res.json();

  const prices = {};
  for (const update of data.parsed) {
    prices[update.id] = Number(update.price.price) * Math.pow(10, update.price.expo);
  }
  return prices;
}

// Use immediately, then connect SSE for updates
const prices = await seedPrices([
  'ff61491a931112ddf1bd8147cd1b641375f79f5825126d665480874634fd0ace',
  'eaa020c61cc479712813461ce153894a96a6c00b21ed0cfc2798d1f9a9e9c94a',
]);

Converting Prices

// Raw Pyth format to USD
const raw = "160025000000";
const expo = -8;
const usd = Number(BigInt(raw)) * Math.pow(10, expo);
// = 1600.25

// WAD format to USD (blend fields)
const wad = "1600275000000000000000";
const usdFromWad = Number(BigInt(wad)) / 1e18;
// = 1600.275
