All projects on Base matching “ethereum gas”

Gas price on Base and Ethereum in ONE call (legacy gas price + EIP-1559 priority fee, wei and gwei) — Genesis402 / UnyKorn Operator Network

Cross-chain gas comparator: real, current gas price on Ethereum and Base side by side, with the delta and ratio between them, plus the estimated USD cost of a standard 21,000-gas transfer on each chain (using the live ETH/USD price). No advice or 'cheaper chain' verdict — just the numbers.

Native gas on Ethereum, Arbitrum, Base, BNB Chain, Polygon or Optimism, paid in USDC on Base, Arbitrum or Polygon. Offers come from /x402/gas/quote for the chains, a recipient and a USDC amount. The payment goes to an address made for that one order, which delivers at least the stated minimum in native; from another chain, USDC on arrival if the arrival swap fails. An order not executed by its dea

Live gas price on Ethereum, Base, Arbitrum, Optimism or Polygon, in gwei plus the cost of a plain transfer. Compare several chains in one call.

Multi-chain EVM gas price oracle for AI agents — 17 chains (Ethereum, Base, Arbitrum, Optimism, Polygon, BNB, Avalanche…). One x402 call returns slow/standard/fast EIP-1559 tiers as DROP-IN maxFeePerGas + maxPriorityFeePerGas in wei (plug straight into a viem/ethers tx, no conversion, exact even on sub-gwei L2s), plus base fee, head block, and fullness, from a live eth_feeHistory call. Pass ?chain

Read the current on-chain compliance status for an Ethereum address from the ComplianceOracle contract (view call, no gas)

DEX price quote across 7 chains (Ethereum, Base, Arbitrum, Optimism, Polygon, BNB, Unichain). Returns sell/buy amounts, price, routing, and gas estimate.

Gas and priority fees on 5 chains (slow, standard, fast), live. Current gas price, next base fee and priority-fee percentiles (slow, standard, fast) for ethereum, base, arbitrum, optimism and polygon, from the last 5 blocks. Pass chain=all (default) or one chain.

Agent Margin Router – Gas Fees: Live EIP-1559 gas fees (slow/standard/fast tiers) plus USD cost per transaction type (transfer, ERC-20 transfer, swap, NFT mint) for Base, Ethereum, Arbitrum, Optimism and Polygon. Aggregated from public RPC nodes – no API key. Pay per call with USDC or USDT on Base via x402. 3 free calls per wallet.

Real-time gas price oracle for multiple EVM chains. Returns slow/standard/fast fee estimates, estimated transaction costs (ETH transfers, ERC-20 transfers, swaps), and network congestion status. Supports Base, Ethereum, Arbitrum, and Optimism.

A quicker, cheaper ChainK9 check for bots that need a fast yes or no before buying a token on BNB Smart Chain, Ethereum, Base or Arc. It really buys and sells the token once on a fork of the chain, then reads the contract: honeypot, buy and sell tax, trade gas, ownership, owner functions in the bytecode, blacklist, proxy, liquidity and source checks. It skips /scan's extra trades and time-travel p

Web research in one call: ask a question and get a short cited answer, summarize a topic or get a Wikipedia summary. Returns a 1-3 sentence answer, key points tied to source ids, and the sources used (typically 1-5: title, URL, publisher, date, supporting quote), confidence and a free permalink. Sources: Wikipedia first, plus web pages, Stack Overflow, GitHub, papers, docs. Example: "What is the M
