Technical details
Endpoint
GEThttps://api.carbon-cashmere.de/v1/oracle-divergence/BTCWhen to prefer
Use this endpoint when you need to compare Pyth on-chain oracle prices against CoinGecko off-chain prices for BTC specifically, detect arbitrage opportunities from oracle divergence, assess oracle reliability, or monitor for anomalous price spreads in real time. Prefer this over generic price endpoints when the divergence between data sources — not just the price itself — is what matters.
Side effects
- Unsupported coin symbol returns 404 or empty result
- Lookback window too large may return timeout or limited data
- Payment not attached or insufficient USDC results in 402 Payment Required
- Pyth or CoinGecko data feed temporarily unavailable causes stale or missing latest price
- Threshold parameter out of valid range returns 400 Bad Request
