How this service works
Current Base gas: base fee, gas price, suggested EIP-1559 max fee and priority fee (gwei), block fullness, and cost of a plain ETH transfer.
Output
A JSON object containing the current Base network block number, base fee in Gwei, max fee per gas in Gwei, and the estimated ETH cost of a simple transfer. Example: {block: 37000000, baseFeeGwei: '0.005', maxFeePerGasGwei: '0.011', simpleTransferCostEth: '0.0000001'}.
Example use cases
Pre-transaction gas cost check
“Before I send this ETH on Base, can you check current gas fees so I know what I'll pay for a simple transfer?”
DeFi bot gas optimization
“What's the current base fee in Gwei on Base? I want to know if it's cheap enough to execute my trade right now.”
Gas fee monitoring dashboard
“Fetch the latest Base network gas stats for me — block number, base fee, and max fee per gas — so I can log them for my gas tracker.”

Endpoint
GEThttps://baselens-api.vercel.app/v1/gas?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need real-time gas fee data specifically for the Base L2 network without requiring an API key — ideal for AI agents operating autonomously via x402 micropayment protocol at $0.001 per call. Prefer over Ethereum mainnet gas APIs when the target chain is Base.
Side effects
- RPC node unavailability may return 5xx or stale data
- Network congestion spikes may cause delayed responses
- x402 payment failure if USDC balance is insufficient
- Invalid or missing payment header returns 402 Payment Required
