EVM developer utilities toolbox

EVM developer utilities toolbox. One call that works out what an EVM value is and converts it every useful way: an address gets its EIP-55 checksum and bytes32 form; a signature its 4-byte selector and event topic; calldata is decoded (ERC-20, NFT, permit, EIP-3009); a bytes32 becomes uint256, address and units; a number converts between wei, gwei, ether (or any decimals) and hex; text gets keccak

Call it from code

This API is run by its own provider and paid directly through x402. We list it so you can find it; we don't route or hold the payment.

import { x402Client, wrapFetchWithPayment } from "@x402/fetch";
import { registerExactEvmScheme } from "@x402/evm/exact/client";

const client = new x402Client();
registerExactEvmScheme(client, { signer: agentAccount });

const pay = wrapFetchWithPayment(fetch, client);
const res = await pay("https://agent-data-tools.revmesh2074.workers.dev/pack/evm-toolbox", { method: "GET" });
console.log(await res.json());
