Bitcoin large transactions in the latest block from mempool.space: total output in BTC, fee, txid and block height, filtered by minBtc. Bitcoin only (no ETH or SOL). Covers the first 25 transactions of the tip block; output total includes change, so it is transaction size, not one wallet's transfer.

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://api.chainmarket-api.workers.dev/api/crypto/whale-alert-transfers", { method: "GET" });
console.log(await res.json());
