How this service works
Current Base mainnet gas: gas price, base fee, and priority fee in gwei, plus estimated execution cost in ETH for an ETH transfer, a USDC transfer, and a typical swap, from the latest block. Useful for timing transactions and budgeting fees before sending. No input needed. Not charged when Base can't be reached.
Output
Returns current Base mainnet gas metrics from the latest block: gas price, base fee, and priority fee in gwei; plus estimated ETH execution costs for three common transaction types — an ETH transfer, a USDC (ERC-20) transfer, and a typical DEX swap.
Example use cases
Pre-swap gas cost check
“Before I execute a token swap on Base, can you check the current gas fees and tell me how much ETH I'll need to cover the transaction cost?”
Gas fee monitoring for DeFi bot
“What are the live gas price, base fee, and priority fee on Base mainnet right now, and what's the estimated ETH cost for a USDC transfer?”
Cost estimation before ETH send
“I want to send some ETH to a friend on Base — can you look up the current gas price and tell me the estimated fee for a standard ETH transfer?”

Endpoint
POSThttps://verifylite.hydratinghealingtouch.workers.dev/chain/gas?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a quick, real-time snapshot of Base mainnet gas conditions including estimated transaction costs for the three most common operation types (ETH send, ERC-20 transfer, swap). It is ideal for DeFi agents, cost-estimation workflows, or pre-transaction fee checks on Base L2 without needing to run your own RPC node.
Side effects
- RPC node unavailable: returns an error if Base mainnet RPC is unreachable
- Stale block data: if the latest block is delayed, gas estimates may lag real-time conditions
- Payment failure: x402 USDC payment not confirmed, request rejected
- Malformed request body: returns validation error if body does not match schema
