How this service works
Base gas oracle - current and next-block base fee, priority-fee percentiles (p10/p50/p90 over the last 20 blocks via eth_feeHistory), slow/standard/fast maxFeePerGas suggestions, legacy eth_gasPrice, the L1 base fee and the cost of an ETH transfer, ERC-20 transfer and DEX swap in ETH and USD.
Output
Returns a JSON object containing: current and next-block base fee in Gwei, priority fee percentiles (p10, p50, p90) derived from the last 20 blocks via eth_feeHistory, slow/standard/fast maxFeePerGas recommendations, legacy eth_gasPrice, the L1 base fee, and the estimated cost of an ETH transfer, ERC-20 transfer, and DEX swap each expressed in both ETH and USD.
Example use cases
Pre-trade gas cost check for DeFi bot
“Before I execute this DEX swap on Base, what's the current fast-lane maxFeePerGas and how much will the swap cost in USD at today's gas prices?”
Gas spike monitoring for wallet app
“Is the Base network congested right now? Show me the current base fee, the p90 priority fee from the last 20 blocks, and what a standard ERC-20 transfer costs in ETH and USD.”
Transaction fee UX display for dApp
“I need to show users an estimated gas fee for sending ETH on Base — can you get me the next-block base fee, a standard priority fee suggestion, and the total cost in both ETH and USD?”
Technical details
Endpoint
GEThttps://mintintel.35-171-220-195.sslip.io/v1/base/gas?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need comprehensive, real-time Base network gas data in a single call — especially when you need both fee suggestions (slow/standard/fast maxFeePerGas) and human-readable USD cost estimates for common transaction types (ETH transfer, ERC-20 transfer, DEX swap). Prefer this over querying eth_gasPrice alone when you need priority-fee percentiles or L1 fee component visibility specific to Base as an L2.
Side effects
- Base RPC node unavailable — upstream JSON-RPC error returned
- eth_feeHistory data insufficient if chain is very new or has few blocks
- USD cost estimates may be stale if Chainlink price feed has not updated recently
- Payment not included or incorrect — x402 payment required error
- Network timeout if Base node is slow to respond
