Skill: Crypto market brief

Bundled execution of the Crypto market brief workflow — Quick crypto market snapshot: price for a specific coin, trending coins, and global market stats (total cap, BTC dominance, volume) — one call. One x402 payment runs 3 underlying tools (crypto-price, crypto-trending, crypto-global); partial-success per step.

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/skill/market-brief", {
  method: "POST",
  headers: { "Content-Type": "application/json" },
  body: JSON.stringify({
    "coin": "bitcoin"
