How this service works
Professional crypto market intelligence. Real-time prices, signals, and market scoring.
Output
Returns a JSON object with per-source prices (DIA, Pyth, CoinGecko) and timestamps, a consensus block with mean, median, max spread percentage, and any identified outlier with its deviation in percent and USD, plus pairwise spread percentages between all three source pairs.
Example use cases
Detect oracle divergence before settlement
“Before we settle this DeFi position, check if DIA, Pyth, and CoinGecko are all in agreement on the ETH price — flag anything if one of them is deviating more than a percentage or two from the consensus.”
Arbitrage signal from oracle spread
“Is there a meaningful spread between the three ETH oracles right now? I want to know the pairwise differences between DIA, Pyth, and CoinGecko — if any pair is diverging significantly, that could be an arbitrage signal worth acting on.”
Trustworthy ETH reference price display
“I need a reliable ETH price to show users on our dashboard — pull the multi-oracle consensus so I'm not relying on just one source, and let me know if any of the three is an outlier I should ignore.”
Technical details
Endpoint
GEThttps://api.carbon-cashmere.de/v1/oracle-consensus-3way/ETHWhen to prefer
Use this endpoint when you need a cross-validated ETH spot price with built-in outlier detection and spread analysis across three independent oracles (DIA, Pyth, CoinGecko). Prefer it over single-source price feeds when data integrity and oracle divergence detection matter, such as in DeFi risk checks, arbitrage detection, or when a trustworthy reference price is needed for settlement or display.
Side effects
- One or more oracle sources unavailable — partial result or error returned
- Coin symbol not supported — 404 or empty response
- Payment not provided or insufficient — 402 Payment Required
- Rate limit exceeded — 429 response
- Network timeout from upstream oracle — stale or missing data
