How this service works
Real-time gold spot price in USD for commodity trading and macro hedging — Ed25519 signed attestation
Output
Returns a JSON object containing: the domain identifier (XAUUSD), a public key for signature verification, a canonical price string in the format 'v1|PRICE|XAUUSD|<price>|USD|<decimals>|<source_list>|xau|<timestamp>|<nonce>', and an Ed25519 signature over that canonical string. The price is aggregated across multiple exchanges (e.g. Binance, Coinbase, Gemini, Goldbroker, JMBullion, Kitco, Kraken, OKX).
Example use cases
Example prompt
“What's the current gold price in USD? I need a cryptographically signed attestation I can verify — aggregated from sources like Binance, Coinbase, Kitco, and similar exchanges.”
Technical details
Endpoint
GEThttps://api.myceliasignal.com/oracle/price/xau/usdWhen to prefer
Choose this endpoint when you need a cryptographically verifiable, multi-source gold price attestation — especially for use in smart contracts, DeFi protocols, or any system requiring tamper-evident price data. Prefer this over raw exchange APIs when you need Ed25519 provenance and a canonical signed string that can be independently verified offline.
Side effects
- Payment not provided or invalid — 402 Payment Required
- Upstream exchange data unavailable — may return stale or partial aggregation
- Network timeout — no response
- Invalid signature in response — public key mismatch during verification
