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. Send POST /api/crypto-news with no required fields (5 optional) and pay $0.002 per call over x402 or MPP (there is no free tier). It returns a JSON object with source, query, match, hours, count and 4 more.

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.

Parameters

Example request

curl -i -X POST https://agent402.tools/api/crypto-news \
  -H "Content-Type: application/json" \
  -d '{"query":"bitcoin","limit":10}'

Without payment this returns HTTP 402 Payment Required with the exact price for crypto-news; any x402 v2 or MPP client pays it and retries.

The hosted connector at https://agent402.tools/mcp needs a payment for crypto-news; the stdio package pays it from a wallet or from AGENT402_CREDITS_KEY. Local install: npx -y agent402-mcp.

Errors and behavior

• Every field is optional. An input the tool rejects returns an HTTP 4xx whose body carries error, tool, expected, required and example.
• A paid call that ends in any status of 400 or above is not charged over x402, MPP or a prepaid credits key: settlement is cancelled when the tool fails. The exception is a Tempo push credential, a transfer the buyer sent before the call: it settles before the tool runs, so if the tool then fails the payment is recorded as a refund owed to the paying wallet.
• Wallet-only: this tool reaches the network or stored state, so it has no proof-of-work tier. A prepaid card-credits key (Authorization: Bearer a402_...) also pays it.
• A GET or HEAD to /api/crypto-news returns the same 402 quote, so the price can be read without a body.
• An Idempotency-Key header makes a retried paid call replay the first 200 instead of charging again (an answer larger than 1 MB is not replayed).

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();
client.setSpendControls?.(false); // keep your own spending ceiling in code
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",
    "limit": 10
  }),
});
