Technical details
Endpoint
GEThttps://api.myceliasignal.com/oracle/price/btc/eur/vwapWhen to prefer
Choose this endpoint when you need a cryptographically verifiable BTC/EUR VWAP price with an Ed25519 signed attestation — ideal for smart contracts, DeFi protocols, or any application requiring tamper-proof price data. Prefer this over simple spot price feeds when auditability and non-repudiation of the price quote are required. Use when your application needs to verify price integrity on-chain or in a trust-minimized environment.
Side effects
- Payment required (402) if x402 payment header is missing or invalid
- Price feed temporarily unavailable due to upstream data source outage
- Invalid or expired Ed25519 signature if service key rotation occurred
- Rate limiting if too many requests are made in a short window
- Network timeout if oracle aggregation takes longer than expected
