Stock quote

Delayed stock quote (open/high/low/close/volume) for a ticker via Stooq's public data — no API key, deterministic JSON. US tickers by default; use suffixed symbols for other markets (e.g. AAPL.US, BMW.DE). ?symbol=AAPL.

Input

Field	Type	Description
symbol *	string	Ticker, e.g. AAPL or BMW.DE (default market: .US)

curl -i "https://agent402.tools/api/stock-quote?symbol=AAPL"

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/stock-quote?symbol=AAPL");

Wallet-only. This tool reaches the network/browser/storage, so it is paid in USDC via x402 (no proof-of-work tier).
