Wallet transaction history

Return the most recent asset transfers (incoming + outgoing) for a wallet address — native coin, ERC-20, ERC-721, ERC-1155 — already merged and sorted newest first. Each row carries the block, tx hash, counterparty, asset, and decimal value. Cap is 100 per direction; widen the window via `fromBlock` if you need deeper history.

Input

Field	Type	Description
address *	string	0x-prefixed 40-char hex wallet address.
network	string	ethereum / base / polygon / arbitrum / optimism (default base).
limit	number	Max transfers per direction (1-100, default 25).
fromBlock	string	Optional starting block in hex (default 0x0 = earliest).

The response is HTTP 402 Payment Required with exact payment requirements. Any x402 v2 client pays automatically and retries:

Paid call (JavaScript agent)

import { wrapFetchWithPayment } from "@x402/fetch";
import { x402Client } from "@x402/core/client";
import { registerExactEvmScheme } from "@x402/evm/exact/client";
import { privateKeyToAccount } from "viem/accounts";

const client = new x402Client();
registerExactEvmScheme(client, { signer: privateKeyToAccount(KEY) });
const payFetch = wrapFetchWithPayment(fetch, client);

const res = await payFetch("https://agent402.tools/api/wallet-transactions", {

  }),
});

Wallet-only. This tool reaches the network/browser/storage, so it is paid in USDC via x402 (no proof-of-work tier).
