Skill: World Bank country data

Bundled execution of the World Bank country data workflow — GDP and population for a country — two key World Bank indicators in one call. One x402 payment runs 2 underlying tools (world-bank-indicator, world-bank-indicator); 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/world-data", {
  method: "POST",
  headers: { "Content-Type": "application/json" },
  body: JSON.stringify({
    "country": "US"
  }),
});
