How this service works
Live Base Mainnet (chainId 8453) gas price and EIP-1559 baseFeePerGas directly from Base public RPC.
Output
A JSON object containing: the data source label ('base-mainnet-rpc'), the chain ID (8453), the network name ('base-mainnet'), the current block number, the current gas price in both Wei and Gwei, and the EIP-1559 baseFeePerGas in both Wei and Gwei.
Example use cases
Pre-transaction gas check on Base
“Before I submit this contract call on Base mainnet, what's the current gas price in Gwei and what's the EIP-1559 baseFeePerGas right now?”
Gas cost monitoring for DeFi bot
“Keep an eye on Base mainnet gas prices for me — tell me the current baseFeePerGas in Gwei so I can decide whether to execute this trade now or wait.”
Real-time gas fee display in wallet app
“What's the live gas price on Base mainnet at the moment, including both the total gas price and the base fee per gas in Wei and Gwei?”
Technical details
Endpoint
GEThttps://penger-oracle.run402.com/api/base-gas?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need real-time, EIP-1559-aware gas price data specifically for Base mainnet (chainId 8453) without running your own RPC node. It is ideal for agents that need to estimate transaction costs, decide whether to submit transactions, or monitor gas conditions on Base L2 — especially in x402-payment-enabled workflows where a pay-per-call model is acceptable.
Side effects
- Base public RPC node is unavailable or rate-limited — may return a server error or stale data
- Network congestion on Base may cause slight latency in block data
- No input validation beyond a GET request — malformed requests return an error
- Returned block number may be slightly behind the chain tip due to RPC propagation delay
