Crypto news headlines

Latest crypto headlines aggregated from the public RSS/Atom feeds of 8 major outlets (coindesk, cointelegraph, decrypt, theblock, bitcoinmagazine, thedefiant, blockworks, cryptoslate), normalized to title, url, source, publishedAt and a plain-text summary, deduplicated by URL and sorted newest first. Optional keyword filter on title + summary (all keywords must match, or match=any), source subset, time window (hours, max 168) and limit (max 50). Feeds are cached 5 minutes; a feed that fails is listed in errors[] and never blocks the rest. No key, no LLM.

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/crypto-news", {
  method: "POST",
  headers: { "Content-Type": "application/json" },
  body: JSON.stringify({
    "query": "bitcoin",
