Technical details
Endpoint
GEThttps://api.myceliasignal.com/oracle/price/btc/usd/vwapWhen to prefer
Choose this endpoint when you need a cryptographically attested, tamper-evident BTC/USD price — particularly for smart contracts, DeFi protocols, or any use case requiring verifiable price provenance. The Ed25519 signature makes it superior to unsigned feeds when auditability or on-chain verification matters.

- Upstream price feed unavailable or stale (503 Service Unavailable)
