Current weather (global)

Current weather conditions for any location on Earth: temperature, feels-like, humidity, wind speed/direction/gusts, precipitation, cloud cover, pressure, and human-readable condition. Send GET /api/weather-current with the required fields lat and lon and pay $0.002 per call over x402 or MPP (there is no free tier). It returns a JSON object with lat, lon, current and source.

Open-Meteo, no key, global. ?lat=48.86&lon=2.35.

Parameters

Example request

curl -i "https://agent402.tools/api/weather-current?lat=48.8566&lon=2.3522"

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

From an MCP client

  "params": {
    "lat": 48.8566,
    "lon": 2.3522
  }
}

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

Errors and behavior

• lat and lon 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/weather-current 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/weather-current?lat=48.8566&lon=2.3522");
