Gas Price

by NetIntel in Onchain & crypto

x402 APIPassing, checked 55 min ago

Live gas prices across Base, Ethereum, Arbitrum, Optimism, and Polygon with USD cost estimates for a transfer, an ERC-20 send, and a swap — keyless, one call, all chains. Per chain: gas price + EIP-1559 base/priority fee in gwei, native-token USD price, 15s cache. L2 figures are execution-gas only (L1 data fee excluded, flagged in findings).

How to call it

# See the payment challenge (nothing is charged)
curl -i -X GET "https://netintel.dev/gas/price?chains=base%2Cethereum"
import { wrapFetchWithPayment } from "@x402/fetch";
import { x402Client } from "@x402/core/client";
import { ExactEvmScheme } from "@x402/evm/exact/client";
import { privateKeyToAccount } from "viem/accounts";

const client = new x402Client().register(
  "eip155:8453",
  new ExactEvmScheme(privateKeyToAccount(process.env.AGENT_KEY)),
);
const pay = wrapFetchWithPayment(fetch, client);

// Not sure it's safe to pay? Preflight it first for $0.005:
// GET https://toolvet.app/api/v1/check?url=https%3A%2F%2Fnetintel.dev%2Fgas%2Fprice
const res = await pay("https://netintel.dev/gas/price?chains=base%2Cethereum");
console.log(await res.json());
