All projects on Base matching “gas”

Base gas oracle / gas price API for AI agents and bots — get the gas price for a transaction on Base in one x402 call. Real-time slow/standard/fast EIP-1559 fee tiers from a live eth_feeHistory call, returned as DROP-IN maxFeePerGas + maxPriorityFeePerGas in wei — plug straight into a viem/ethers transaction, no gwei conversion. Plus base fee, head block, and network fullness. Call it before every

Current Base mainnet gas price (wei/gwei), EIP-1559 base_fee_gwei/priority_fee_gwei, and gas_price_usd. Use when an agent must estimate gas cost in USD before sending a Base transaction.

Stop opening five explorers to price one transaction: one GET returns what each chain is charging for gas right now — for base, eth, arbitrum, optimism and polygon: the current gas price in gwei (with the raw wei the RPC returned), the latest block's base fee, the priority fee a 50th-percentile transaction actually paid across the last five blocks, the next block's base fee under the EIP-1559 form

Current gas price on Base and what a transaction costs in USD right now: base fee, priority tiers, ready-to-sign maxFeePerGas.

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

Base token sell check AT YOUR TRADE SIZE: simulates a buy of amountEth (0.001 to 10 ETH) and an immediate sell inside eth_call (no trade is sent) and reports the buy tax, the sell tax and the round-trip loss including price impact. Uniswap v2, v3, v4 (ETH, WETH, ZORA, USDC quotes) and Aerodrome. Measured at one block, not a guarantee, not financial advice.

Translate a short-drama episode, retaining subtitle cue identity and timing. A private series key carries approved terminology into later episodes and unambiguous renderings into the reverse direction. Output is a draft with mechanical checks and requires review before production approval.

AI text summarization: condenses up to 20k characters into a crisp 250-word summary. Use when you have a long document, article, or transcript and need the gist before reasoning over it.

Paid audiobook narration economics advisor (cycle 207, x402 $0.001) - GET ?title=<BOOK_TITLE>&author=<AUTHOR>&minutes=<N> OR ?sample=1|2|3 OR POST application/json {title, author, minutes, hourly_llm_rate_usd, tts_usd_per_million_chars}.

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.

Gas / fee estimate. Current fee tiers for a chain as decimal strings with explicit units. EVM: confidence levels (default 99/95/90/80/70) in gwei with base fee, priority fee and max fee. Aptos: deprioritized/regular/prioritized gas unit prices in octas per gas unit. Data older than its freshness budget is an error, never a stale answer.

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.

Is Base live, and what is the latest block? Returns number, timestamp, gas used, gas limit and transaction count of the latest block, or of a given numero ($0.001 per call).

Gas sponsorship for one ERC-4337 user operation on Base (EntryPoint v0.8). Price = max($0.03, 1.3× the op's gas cap); this is the floor — send your user operation to get the exact quote.

Then POST the sign

Returns a real-time mempool anomaly score with current gas price vs 20-block median, pending whale swaps, and contract deploy counts. Poll every 5s to monitor mempool for MEV or sandwich attacks and catch gas spikes or large pending swaps as they happen, before they land on-chain.

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.

Audit real gas spend across up to 20 Base mainnet transaction hashes you provide — total/average gas used, cost in ETH, per-tx breakdown. POST body required. Experimental/informational only — not financial advice.

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.

Price a swap without building a transaction. Returns expected input, output, and gas without constructing an executable transaction. Quotes are informational and can change with liquidity and chain state.

Produce a factual snapshot of current x402 payment authority for one unpaid v2 requirement and one public EVM payer: selected scheme/network/asset/amount/payTo/transfer method, same-block token balance, canonical token-spender allowance when that path applies, and declared recovery-path classification. Does not sign, approve, construct a transaction, judge native gas, or recommend whether to buy.

Fee inputs for the next transaction: gas ladder for Base or Ethereum (slow/normal/fast, priority fee, max fee, EIP-1559 base fee) or the priority-fee ladder for Solana, plus the native token price. One call for the numbers a transaction builder needs.

A signed, timestamped read from Base mainnet: whether a transaction landed and in which block, an address's ETH and USDC balance, or the current block height and gas price. Use the tx query when you paid over x402, received settlement_pending, and need it resolved — the transaction is in a block with status 1, or it is not. Read through a commercial node, not the public RPC. Verify with soren.com/

Verify an onchain payment or investigate a failed Base transaction in one call with transaction, receipt, success status, confirmations, gas and fee context.

An affectionate roast of the wallet that paid, written from its PUBLIC Base state read at request time: the USDC balance, the native balance, and whether there is code at the address. Those become words — dust, pocket, purse, vault; gas or none; contract or plain — and a hand-written line is picked from them, keyed to your address and the UTC date, so it holds all day. EXACT AMOUNTS ARE NEVER RETU
