Crypto market pulse — latest Ethereum (or Base) block context plus top crypto gainers and losers by 24h change, in a single call. Returns: block_number, timestamp, gas info (base_fee_gwei, gas_used/limit, tx_count), and top movers (symbol, name, price_usd, change_24h, volume_24h, market_cap). Use for crypto portfolio context, on-chain/market correlation, or pre-trade situational awareness. Free upstream: DRPC + CoinGecko. $0.007/call — 30% below the comparable two-endpoint chain.

// npm i x402-fetch viem
import { wrapFetchWithPayment } from "x402-fetch";
import { createWalletClient, http } from "viem";
import { privateKeyToAccount } from "viem/accounts";
import { base } from "viem/chains";

const account = privateKeyToAccount(process.env.PRIVATE_KEY); // funds USDC on Base
const wallet = createWalletClient({ account, chain: base, transport: http() });
const fetchWithPay = wrapFetchWithPayment(fetch, wallet);

// Pays the $0.007 USDC automatically on the 402, then returns the real response:
const res = await fetchWithPay("https://the-stall.intuitek.ai/cap/crypto-pulse", { method: "GET" });
console.log(await res.json());

# pip install x402 eth-account httpx
import os, asyncio
from eth_account import Account
from x402.clients.httpx import x402HttpxClient

account = Account.from_key(os.environ["PRIVATE_KEY"])  # funds USDC on Base

async def main():
    async with x402HttpxClient(account=account) as client:
        # x402 handles the 402 -> pay ($0.007 USDC) -> retry automatically
        r = await client.get("https://the-stall.intuitek.ai/cap/crypto-pulse")
        print((await r.aread()).decode())

# 1) An unpaid request returns HTTP 402 with the exact payment terms:
curl -i "https://the-stall.intuitek.ai/cap/crypto-pulse"

# 2) Paying + retrying requires an x402 client that can sign the USDC
#    authorization (curl alone cannot). See the JS / Python tabs below.
