How this service works
Real-time Solana price in USD, aggregated from multiple exchanges — Ed25519 signed attestation
Output
A JSON object containing the current SOL/USD spot price along with an Ed25519 cryptographic signature attesting to its authenticity, enabling downstream verification that the price data has not been tampered with.
Example use cases
Verify Solana price for smart contract execution
“Before I execute this token swap on-chain, I need to fetch the current SOL/USD price with a valid Ed25519 signature so the smart contract can verify it hasn't been tampered with. Can you grab that signed price attestation from MyceliaSignal?”
Prove price accuracy in DeFi liquidation event
“A user is disputing a liquidation that happened at a specific moment. I need to retrieve the signed SOL/USD price from that timestamp to prove the price was accurate when we executed the liquidation. Get me that cryptographically verified oracle reading.”
Build trustless cross-chain price bridge
“I'm setting up a price feed that other blockchains will trust. Fetch me the current Solana price with its Ed25519 signature so I can publish it as a verifiable price point that downstream systems can independently validate without needing to trust us as intermediaries.”
Technical details
Endpoint
GEThttps://api.myceliasignal.com/oracle/price/sol/usdWhen to prefer
Choose this endpoint when you need a cryptographically verifiable SOL/USD price — for example, in smart contracts, DeFi protocols, or any system that requires trustless price attestation. Prefer it over unauthenticated price APIs when tamper-evidence and Ed25519 signature verification are required. Ideal for agentic workflows that need to prove the price used was accurate at a given moment.
Side effects
- Payment not included or insufficient (402 Payment Required — must include $0.01 USDC via x402 protocol)
- Price feed temporarily unavailable (503 Service Unavailable)
- Signature verification failure if attestation key rotated
- Stale price data if upstream exchange feed is delayed
