How this service works
Brent crude oil spot price — international benchmark for global energy markets and macro hedging — Ed25519 signed attestation
Output
Returns the current Brent Crude Oil price as an Ed25519-signed attestation object, allowing the caller to cryptographically verify the authenticity and integrity of the price data. Includes the price value and a digital signature tied to MycealiaSignal's oracle key.
Example use cases
Verify energy hedge contract inputs
“I'm locking in a fuel surcharge adjustment for our shipping contracts next quarter. Grab the latest Brent crude price from MycealiaSignal with the Ed25519 signature so I can prove to our auditors that we used authenticated market data.”
Detect suspicious commodity price movements
“Set up an alert that pulls the signed Brent crude price every hour. If the cryptographically verified price swings more than 5% from our internal baseline, flag it as potentially anomalous and log the attestation for investigation.”
Feed blockchain oracle with verifiable data
“Our DeFi protocol needs to settle some oil-backed derivatives today. Fetch the current Brent crude spot price with the Ed25519 signature attached so we can submit it as tamper-proof proof to the smart contract.”
