Price Proxy Reference

The Ryze Price Proxy serves real-time execution prices used by the protocol. It streams low-latency price data from Pyth Pro (Lazer) and optionally blends it with CEX reference prices, exposing a Hermes-compatible API.

Why Use the Proxy?

• Execution prices: Returns the same blended prices the Ryze Router uses for quote calculations
• Hermes-compatible: Drop-in replacement for hermes.pyth.network -- same SSE and REST format
• Low latency: Powered by Pyth Pro (Lazer) with ~200ms updates
• No API key needed: The proxy handles Pyth Pro authentication internally

Endpoints

Method	Path	Description
GET	/v2/updates/price/stream	SSE price stream (real-time)
GET	/v2/updates/price/latest	Latest cached prices (one-shot)
GET	/health	Service health and diagnostics

Price Format

Prices follow the standard Pyth format:

{
  "id": "ff61491a931112ddf1bd8147cd1b641375f79f5825126d665480874634fd0ace",
  "price": {
    "price": "160025000000",
    "conf": "0",
    "expo": -8,
    "publish_time": 1713200000
  },
  "ema_price": {
    "price": "160025000000",
    "conf": "0",
    "expo": -8,
    "publish_time": 1713200000
  }
}

To convert to a human-readable price:

// price = raw * 10^expo
const raw = BigInt("160025000000");
const expo = -8;
const price = Number(raw) * Math.pow(10, expo);
// = 1600.25

Blended Prices

When blending is active, each price includes a blend field showing how the execution price is computed:

{
  "id": "ff61491a...",
  "price": { "price": "160027500000", "conf": "0", "expo": -8, "publish_time": 1713200000 },
  "ema_price": { ... },
  "blend": {
    "token": "0x4200000000000000000000000000000000000006",
    "pythPrice": "1600250000000000000000",
    "cexPrice": "1600300000000000000000",
    "blendFactor": "500000000000000000",
    "blendedPrice": "1600275000000000000000"
  }
}

Field	Description
pythPrice	Pyth oracle price in WAD (1e18 = $1)
cexPrice	CEX reference price in WAD
blendFactor	Blend ratio in WAD: 0 = pure Pyth, 1e18 = pure CEX
blendedPrice	Final execution price in WAD

The blended price is what the Ryze Router uses for swap calculations.
