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/edgar-recent-ipos?days=30&form=S-1&limit=25");

• SEC regulatory monitoring - The 'who just filed / who just bought / what just IPO'd / what does the full-text search say' monitoring loop. Five EDGAR tools composed: full-text search for a keyword, surface recent filings on the matched companies, pull insider Form 4 transactions, pull 13F institutional holdings changes, and check the IPO calendar. Different from sec-filings-deep-dive (which goes deep on one company's earnings) - this is the wide-and-recent radar.
• IPO watch - What companies are going public? Recent S-1/IPO filings from EDGAR plus a web search for IPO news.
