How this service works
Ethereum 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 and the cost of an ETH transfer, ERC-20 transfer and DEX swap in ETH and USD.
Output
A JSON object containing current Ethereum base fee in Gwei, next-block base fee estimate, priority fee percentiles (p10/p50/p90) derived from the last 20 blocks via eth_feeHistory, slow/standard/fast maxFeePerGas suggestions, legacy eth_gasPrice, and estimated costs in both ETH and USD for a plain ETH transfer, an ERC-20 token transfer, and a DEX swap.
Example use cases
Pre-trade gas cost check for DeFi
“Before I submit this Uniswap swap, what's the current Ethereum gas situation — base fee, recommended fast maxFeePerGas, and what the swap will roughly cost me in USD?”
Gas fee monitoring for wallet app
“What are the current slow, standard, and fast gas fee suggestions on Ethereum, plus the priority fee percentiles over the last 20 blocks?”
ETH transfer cost estimation
“How much will it cost in ETH and USD to send ETH from one wallet to another right now, based on the current base fee and standard priority fee?”
Technical details
Endpoint
GEThttps://mintintel.35-171-220-195.sslip.io/v1/eth/gas?utm_source=zero.xyzWhen to prefer
Use this endpoint when an agent needs real-time Ethereum gas fee data including both EIP-1559 (base fee + priority fee) and legacy gas price, and wants ready-made slow/standard/fast fee suggestions plus concrete transaction cost estimates in USD — avoiding the need to query eth_feeHistory and run the fee math independently.
Side effects
- Ethereum RPC node is temporarily unavailable — returns a 5xx error
- eth_feeHistory call fails if the node has insufficient block history
- USD cost estimates may be stale if the ETH/USD price feed is delayed
- Rate limiting or payment failure returns 402 or 429 status
- Response may be cached briefly, so values can lag by a few seconds
