```

Example prompt: What's the current price divergence between the Pyth oracle and CoinGecko spot price for ETH — show me the spread stats and any recent threshold exceedances?

## When to prefer this

Use this endpoint when you need to detect discrepancies between on-chain Pyth oracle prices and CoinGecko spot prices for a specific cryptocurrency — ideal for oracle arbitrage signal detection, data quality monitoring, or flagging potential oracle manipulation or lag. Prefer this over raw price feeds when you specifically need the differential/spread between oracle and CEX/aggregator spot data.

## Known failure modes

- Coin not in the supported 28-coin list returns a 404 or error response
- Upstream Pyth or CoinGecko data unavailability may cause stale or missing stats
- Invalid coin identifier format returns a validation error
- Network timeout or service downtime returns a 5xx error
