blockchain-gas-price-data

FuelScout cheapest-fuel query (station-level where open data exists, regional averages otherwise)

Block number, hash, timestamp as ISO UTC, base fee in gwei, gas used and limit with utilisation, transaction count and miner, for the latest block or the height you pass. Decoded from hex so no client-side conversion is needed.

Base gas price now: what an ETH transfer, a USDC transfer and a Uniswap swap cost in USD, L1 fee included. What a transaction on Base costs right now, in dollars, including the L1 data fee most gas trackers leave out. Read from real receipts in the latest Base blocks: the median a plain ETH transfer, a USDC transfer and a Uniswap swap actually paid (L2 fee + L1 fee), what the same gas costs at the current base fee and median tip, and the tip spread over 20 blocks.

What a given operation SHOULD cost on Arc right now, in dollars - a price list computed at the gas price read at this block, and the companion to /api/x402/arc-gas which measures what transactions ACTUALLY cost across a spread of blocks. Use this one to quote an operation, that one to budget for the tail: the 20 gwei floor holds most of the time but is not a cap, and the response says so.

Returns the current gas price on the Ethereum network. No inputs. Output: gas price in wei as a hex string.

Gas Estimate (bsc). BNB Chain (BSC) gas estimate for a transaction (to, data, value, from) with the current gas price and total fee in BNB, and a clear revert reason if the call would fail. Use it to price or pre-check a transaction before sending.

Gas Estimate (base). Base gas estimate for a transaction (?to=, ?from=, ?data=, ?value=) with current gas price and estimated fee in the native coin; reverts reported cleanly.

Gas Estimate (ethereum). Ethereum gas estimate for a transaction (?to=, ?from=, ?data=, ?value=) with current gas price and estimated fee in the native coin; reverts reported cleanly.

Gas Estimate (arbitrum). Arbitrum gas estimate for a transaction (?to=, ?from=, ?data=, ?value=) with current gas price and estimated fee in the native coin; reverts reported cleanly.

Gas Estimate (optimism). Optimism gas estimate for a transaction (?to=, ?from=, ?data=, ?value=) with current gas price and estimated fee in the native coin; reverts reported cleanly.

Gas Estimate (polygon). Polygon gas estimate for a transaction (?to=, ?from=, ?data=, ?value=) with current gas price and estimated fee in the native coin; reverts reported cleanly.

EVM Gas Price: live gas price on Base and Ethereum in gwei + USD Executed deterministically by the AmanChain node against live consensus state (real blocks, pools, balances) — paid per call via x402, settled in USDC on Base. Input: JSON body {"serviceId":"aman-gas-price","request":" "}. No account, no API key.

Current gas conditions on Base, read live from a public node: gas price, base fee of the latest block, suggested priority fee, latest block number and timestamp. No parameters. No third-party API, no cache.

Use when an agent needs the current gas price on an EVM chain before sending a transaction — cost estimation, fee budgeting, or deciding whether to transact now. Pass network (base, polygon, arbitrum, avalanche); returns live eth_gasPrice plus priority fee in wei and gwei from the chain's public RPC. Resale permitted: buyer may resell this data output at their own price.

Returns current blockchain transaction fee estimates.

Base gas price, base fee and priority fee at head. Not an estimate of a specific call. Unread RPC is not zero.

Current peaq network gas price (wei + gwei)

Current Base gas price with common operations already costed - whether a transfer is affordable right now, not a raw wei number. Answered from live Base mainnet, not a model, so it is current and costs the same every time. Use it for: What does an ERC-20 transfer cost on Base right now?; Is gas cheap enough to settle a batch this minute?

Use when you need current gas prices on Base, Ethereum, Arbitrum, Optimism or Polygon before sending a transaction: legacy gas price, latest base fee and suggested priority fee in gwei, plus the block they refer to.

Fetch current weekly EIA retail prices for regular gasoline, premium gasoline and No. 2 diesel by national or EIA area code, with an explicit red/dyed diesel limitation and source metadata.

Current Base network gas price, read live from a public Base RPC node (eth_gasPrice) and returned in both wei and gwei with the snapshot block it was read at.

Estimate the gas a transaction will use (eth_estimateGas) and its cost at the current gas price, or the revert reason if it would fail. Nothing is sent. Works on Base, Ethereum, Arbitrum, Optimism, Polygon, BNB Chain, Avalanche, Gnosis, Linea, Scroll, Sonic and Unichain.

Gas price tracker: live gas and priority fees for Ethereum, Base, Arbitrum, Polygon and Solana in one call, from public nodes. Returns base fee, slow/standard/fast tips, max fee, block congestion, and the USD cost of a transfer, an ERC-20 transfer and a swap, plus the cheapest chain. Optional chain. 0.002 USDC (Base/Polygon/Arbitrum/Solana/Avalanche/Sei). Errors are never charged: 400 bad input, 422 nothing found or target unreachable, 503 busy.

Live gas price on Base or Ethereum (gwei, base fee, priority fee) plus estimated USD cost of an ETH transfer, an ERC-20 transfer and a DEX swap, including Base L1 data fee. Priced with the Chainlink ETH/USD oracle.
