Korean data (remote)

Remote, no install needed. 1gateway wraps Korean government open APIs (which need a Korean account and key, and
answer in Korean XML) and returns normalized English JSON with Korean names kept alongside.

How to call (remote, no install needed)

Nothing to install or host: this skill calls the remote 1gateway API over HTTPS. Each call is paid per request
with USDC on Base through the x402 protocol (HTTP 402). No signup, no API key.

1. Optional, free: see the exact price. An unpaid request returns HTTP 402 with a PAYMENT-REQUIRED header
   (base64 JSON quote). curl -i "https://1gateway.dev/v1/calendar/holidays?year=2026"
2. Pay and get the data with any x402 client that has a funded Base wallet, for example:
   • npx agentcash fetch "https://1gateway.dev/v1/calendar/holidays?year=2026" (AgentCash wallet)
   • npx awal x402 pay "https://1gateway.dev/v1/calendar/holidays?year=2026" (Coinbase Agentic Wallet)
   • Node: @x402/fetch, see below
3. Billing: payment settles only after a 2xx response. Any 4xx/5xx (bad input, no data, upstream error) is not
   charged. Inputs are validated before the 402 wherever possible.

// npm i @x402/fetch @x402/evm viem
import { wrapFetchWithPaymentFromConfig } from "@x402/fetch";
import { ExactEvmScheme } from "@x402/evm";
import { privateKeyToAccount } from "viem/accounts";
const payFetch = wrapFetchWithPaymentFromConfig(fetch, {
  schemes: [{ network: "eip155:8453", client: new ExactEvmScheme(privateKeyToAccount(process.env.X402_WALLET_KEY as `0x${string}`)) }],
  spendControls: { maxAmountPerPayment: "$0.01" }, // refuse anything pricier than expected
});
const res = await payFetch("https://1gateway.dev/v1/calendar/holidays?year=2026");
console.log(await res.json());
