Historical weather (global)

Historical daily weather for any location and date range (up to 1 year): high/low temp, precipitation, wind, conditions. Send GET /api/weather-history with the required fields lat, lon, start and end and pay $0.002 per call over x402 or MPP (there is no free tier). It returns a JSON object with lat, lon, days and source.

Open-Meteo archive, no key, global. Data from 1940 to 5 days ago. ?lat=51.51&lon=-0.13&start=2025-06-01&end=2025-06-07.

Parameters

Example request

curl -i "https://agent402.tools/api/weather-history?lat=51.5074&lon=-0.1278&start=2025-06-01&end=2025-06-07"

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

From an MCP client

catalog.call {
  "slug": "weather-history",
  "params": {
    "lat": 51.5074,

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

Errors and behavior

• lat, lon, start and end 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-history 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-history?lat=51.5074&lon=-0.1278&start=2025-06-01&end=2025-06-07");
