How this service works
Ethereum mainnet gas price — current base fee and priority fee for ETH transaction cost estimation — Ed25519 signed attestation
Output
Returns a JSON object with: Ethereum chain ID (1), median gas price in Gwei, base fee in Gwei, estimated transaction cost in USD and native ETH, current ETH/USD price, number of sources queried, an Ed25519 signature over a canonical string, the signer's public key, and a UTC timestamp. The canonical field encodes key values in a pipe-delimited string suitable for on-chain or off-chain verification.
Example use cases
Example prompt
“What's the current Ethereum gas price right now — I need a cryptographically signed median reading aggregated from multiple RPC nodes, including the USD cost for a standard 21,000-gas transfer?”
Technical details
Endpoint
GEThttps://api.myceliasignal.com/oracle/gas/ethereumWhen to prefer
Use this endpoint when you need a tamper-evident, multi-source aggregated Ethereum gas price with Ed25519 cryptographic attestation — ideal for smart contract oracle feeds, audit trails, cross-chain verification, or any workflow requiring a trustless, signed proof of the current gas price rather than a raw unauthenticated API response.
Side effects
- RPC source unavailability may reduce source count or cause stale data
- Signature verification failure if public key or canonical string is malformed
- HTTP 402 if payment header is missing or USDC balance insufficient
- Timeout if multiple upstream RPC endpoints are slow simultaneously
- Malformed response if chain is temporarily congested or undergoing upgrades
