Current time

Current time: UTC ISO, epoch seconds/ms, day of week/year, ISO week - optionally rendered in any IANA timezone via ?tz=. Send GET /api/time with no required fields (1 optional) and pay $0.001 per call over x402 or MPP, or call it free by solving a proof-of-work challenge. It returns a JSON object with utc, epochSeconds, dayOfWeek and local.

Parameters

Example request

curl -i "https://agent402.tools/api/time?tz=America%2FNew_York"

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

Example response

{
  "utc": "2026-06-11T10:00:00.000Z",
  "epochSeconds": 1781172000,
  "dayOfWeek": "Thursday",
  "local": "2026-06-11 06:00:00 EDT"
}

From an MCP client

catalog.call {
  "slug": "time",
  "params": {
    "tz": "America/New_York"
  }
}

On the hosted connector at https://agent402.tools/mcp, catalog.call runs time free (rate-limited, no wallet). Local install: npx -y agent402-mcp.

Errors and behavior

• Every field is optional. An input the tool rejects returns an HTTP 4xx whose body carries error, tool, expected, required and example.
• 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.
• Free tier: no outbound network call leaves the server for this tool, so proof-of-work (16 leading zero bits of sha256) pays for it.
• A POST with a JSON body to /api/time 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/time?tz=America%2FNew_York");

No wallet? Pay with compute

Fetch a challenge, solve the sha256 puzzle (16 leading zero bits, a fraction of a second of CPU), and resend with the X-Pow-Solution header:

import { createHash } from "node:crypto";
const lz = (b) => { let t = 0; for (const x of b) { if (!x) { t += 8; continue; } t += Math.clz32(x) - 24; break; } return t; };
const c = await (await fetch("https://agent402.tools/api/pow/challenge?slug=time")).json();
let n = 0;
while (lz(createHash("sha256").update(c.challenge + ":" + n).digest()) < c.difficulty) n++;
await fetch("https://agent402.tools/api/time?tz=America%2FNew_York", { method: "GET", headers: { "X-Pow-Solution": c.token + ":" + n } });
