How this service works
USDT/EUR derived rate for stablecoin exposure in European markets — Ed25519 signed attestation
Output
Returns a JSON object with: the currency domain (USDTEUR), a public key for signature verification, a canonical price string encoding version, price type, pair, rate value, quote currency, decimal precision, source list, derivation method, and Unix timestamp, plus an Ed25519 signature over the canonical string — allowing downstream consumers to cryptographically verify the price data has not been tampered with.
Example use cases
Example prompt
“What's the current USDT/EUR exchange rate? I need a cryptographically signed price attestation aggregated from multiple sources like Binance, Kraken, and ECB so I can verify it on-chain.”
Technical details
Endpoint
GEThttps://api.myceliasignal.com/oracle/price/usdt/eurWhen to prefer
Use this endpoint when you need a cryptographically verifiable, multi-source aggregated USDT/EUR price — particularly for smart contracts, DeFi applications, or any use case where tamper-proof price provenance matters. Prefer over raw exchange APIs when an Ed25519 signed attestation is required for on-chain or trustless verification. The aggregation across sources like Binance, Kraken, Bitstamp, ECB, and others reduces single-source manipulation risk.
Side effects
- Payment required (402) if x402 payment header is missing or invalid
- Source aggregation failure if upstream price feeds are unavailable
- Stale price if all data sources are temporarily down
- Signature verification failure if public key is mismatched
- Network timeout if oracle service is unreachable
