Public holidays

Public holidays for a country and year via Nager.Date (keyless, 100+ countries): date, local name, English name, nationwide flag, and holiday types. Send GET /api/public-holidays with the required fields country and year and pay $0.001 per call over x402 or MPP (there is no free tier). It returns a JSON object with country, year, count and holidays.

Pairs with /api/business-days and /api/country-info. ?country=US&year=2026

Parameters

Example request

curl -i "https://agent402.tools/api/public-holidays?country=US&year=2026"

Without payment this returns HTTP 402 Payment Required with the exact price for public-holidays; any x402 v2 or MPP client pays it and retries.

Example response

{
  "country": "US",
  "year": 2026,
  "count": 17,
  "holidays": [
    {
      "date": "2026-01-01",
      "localName": "New Year's Day",
      "name": "New Year's Day",
      "global": true,
      "counties": null,

From an MCP client

catalog.call {
  "slug": "public-holidays",
  "params": {
    "country": "US",
    "year": 2026
  }
}

The hosted connector at https://agent402.tools/mcp needs a payment for public-holidays; the stdio package pays it from a wallet or from AGENT402_CREDITS_KEY. Local install: npx -y agent402-mcp.

Errors and behavior

• country and year are required. An input the tool rejects returns an HTTP 4xx whose body carries error, tool, expected, required and example, so the caller can correct it.
• A paid call that ends in any status of 400 or above is not charged over x402, MPP or a prepaid credits key: settlement is cancelled when the tool fails. The exception is a Tempo push credential, a transfer the buyer sent before the call: it settles before the tool runs, so if the tool then fails the payment is recorded as a refund owed to the paying wallet.
• Wallet-only: this tool reaches the network or stored state, so it has no proof-of-work tier. A prepaid card-credits key issued earlier (Authorization: Bearer a402_...) also pays it.
• A POST with a JSON body to /api/public-holidays is served as this GET, with the body as the input.
• An Idempotency-Key header makes a retried paid call replay the first 200 instead of charging again (an answer larger than 1 MB is not replayed).

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();
client.setSpendControls?.(false); // keep your own spending ceiling in code
registerExactEvmScheme(client, { signer: privateKeyToAccount(KEY) });
const payFetch = wrapFetchWithPayment(fetch, client);

const res = await payFetch("https://agent402.tools/api/public-holidays?country=US&year=2026");

Part of these workflows

Public holidays is one step in this skill pack, each sold as a single call:

• Locale brief - "Can I reach this counterparty this week?" - country facts, this year's public holidays, working days remaining this week, and what time it is there right now, in one call.
