How this service works
Current gas price on any of ten EVM chains — Genesis402 / UnyKorn Operator Network
Output
A JSON object with a boolean ok field, a type field identifying the response as evm-gas-price, and a receipt object containing the transaction hash, amount in USD, and a receipt ID, plus a generated_at ISO 8601 timestamp. The gas price data for the requested chain is included in the response payload.
Example use cases
Pre-transaction cost check on Ethereum
“Before I send this ETH transfer, what's the current gas price on Ethereum so I can estimate my fee?”
DeFi bot timing on Polygon
“Check the current gas price on Polygon — I want to know if it's low enough to execute my swap right now.”
Multi-chain deployment planning
“What's the gas price on Base at this moment? I'm deciding which chain to deploy my contract on and want to compare costs.”

Endpoint
POSThttps://twin.unykorn.org/evm-gas-price?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need real-time gas price data for any of the ten supported EVM chains (Ethereum, Base, Polygon, Arbitrum, Optimism, BSC, Avalanche, Gnosis, Linea, Scroll) in a single low-latency call. It is ideal for pre-transaction cost estimation, DeFi bot timing logic, or cross-chain fee comparisons. Prefer this over scraping block explorers or maintaining your own RPC connections when you need a pay-per-call, infrastructure-free solution with x402 micropayment billing.
Side effects
- Unsupported chain name passed — only the ten enum values are accepted
- Network connectivity issues to the target chain's RPC
- Payment failure via x402 protocol results in 402 response
- Malformed request body or missing chain parameter
- Transient upstream RPC unavailability for the requested chain
