How this service works
Professional crypto market intelligence. Real-time prices, signals, and market scoring.
Output
A JSON object with: the coin ticker, statistical spread metrics (p25/p75/median/abs_max/abs_p95 of spread_pct, exceedance_rate, exceeded_threshold count, sample count), a list of individual divergence events (timestamp, direction of divergence, Pyth price, CoinGecko price, spread_pct, Pyth confidence), filter settings used (threshold_pct, lookback_minutes), and the latest snapshot (timestamp, Pyth price, CoinGecko price, spread_pct).
Example use cases
ETH oracle manipulation risk check
“I need to know if there's any suspicious oracle manipulation happening with ETH right now — pull the latest Pyth vs CoinGecko divergence data and flag if the exceedance rate looks abnormal or if any recent spread events crossed dangerous thresholds.”
DeFi liquidation oracle trustworthiness
“Before we trigger any liquidations in our DeFi protocol, check whether the ETH oracle price is trustworthy right now — compare what Pyth and CoinGecko are showing, and let me know if the spread or exceedance events over the last 30 minutes give us any reason to pause.”
ETH arbitrage spread signal detection
“Scan for any meaningful price divergence between the Pyth and CoinGecko ETH feeds in the past hour — I want the spread percentiles, any exceedance events, and the latest snapshot so I can decide if there's an actionable arbitrage signal here.”
