How this service works
Web page to clean Markdown for AI agents. Pay per call with x402 (USDC on Base).
Output
A JSON object containing the current block number, chain name, max fee in gwei, base fee in gwei, gas price in gwei, priority fee in gwei, and estimated ETH cost for a standard transfer on the specified EVM-compatible network.
Example use cases
Pre-transaction gas check on Base
“Before I send this USDC transfer, can you check what the current gas price is on Base so I know what fees to expect?”
Gas cost comparison across chains
“What's the current gas price on Arbitrum right now — I want to see the base fee and priority fee in gwei.”
DeFi bot gas optimization
“Check the current gas fees on Ethereum for me — I need the max fee per gas and base fee in gwei to decide whether to execute this trade now.”
Technical details
Endpoint
GEThttps://138-197-15-135.sslip.io/v1/evm/gas?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need real-time EVM gas price data for Base, Ethereum, Arbitrum, or Optimism and want a simple, pay-per-call API without managing RPC node subscriptions. Ideal for agents that need to estimate transaction costs before execution or monitor fee conditions across multiple EVM chains.
Side effects
- Invalid chain parameter returns an error or defaults to Base
- Network connectivity issues to the target blockchain node may cause stale or unavailable data
- Unsupported chain name results in no data returned
- High network congestion may cause slight latency in retrieving latest block data
