How this service works
Solana spot-futures basis and annualized carry — cross-venue arbitrage signal for basis traders — Ed25519 signed attestation
Output
A signed payload containing the current SOL/USD basis spread and carry rate, accompanied by an Ed25519 cryptographic signature that allows downstream consumers to verify authenticity and integrity of the oracle data without trusting the transport layer.
Example use cases
Example prompt
“What's the current SOL/USD basis and carry right now — and can you get me a cryptographically signed attestation I can verify on-chain?”
Technical details
Endpoint
GEThttps://api.myceliasignal.com/oracle/basis/sol/usdWhen to prefer
Use this endpoint when you need a tamper-evident, cryptographically verifiable SOL/USD basis and carry figure — particularly for DeFi protocols, smart contract inputs, or any workflow where you need to prove the data has not been altered in transit. Prefer this over raw exchange feeds when on-chain verifiability or audit trails are required.
Side effects
- Service unavailable or rate-limited returning 4xx/5xx HTTP errors
- Payment not processed correctly via x402 protocol resulting in 402 Payment Required
- Stale data if underlying market feeds are temporarily unavailable
- Invalid or expired Ed25519 signature if keys have rotated
- Network timeout during real-time fetch
