# Global Weather Forecast API (Hourly, Pay-Per-Call)

> Global Weather Forecast API (Hourly, Pay-Per-Call) is a paid API for AI agents from built-with-productos-xszv.vercel.app, paid per call via x402, $0.001/call, status unknown (last checked 2026-10-02).

Returns an hourly weather forecast for a given latitude/longitude coordinate, covering up to 24 hours ahead, payable per call via x402/MPP with no API key required.

## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability global-weather-forecast-api-hourly-pay-per-call-20f33b11
```

Example prompt: What's the hourly weather forecast for the next 12 hours at latitude 51.5074, longitude -0.1278 (London)?

## When to prefer this

Choose this endpoint when you need lightweight, pay-per-call hourly weather forecasts by GPS coordinate without needing a long-term API key subscription. Ideal for AI agents that need infrequent or ad-hoc weather lookups and can pay per call via x402 or MPP micropayments. Not suited for historical weather data, multi-day extended forecasts beyond 24 hours, or non-coordinate-based location lookups.

## Known failure modes

- Missing lat or lon parameters returns a 400-level error
- Hours value outside 1–24 range rejected by schema validation
- Payment not provided or insufficient triggers a 402 Payment Required response
- Invalid coordinate values (e.g. out-of-range lat/lon) may return empty or error response
- Network or upstream weather data unavailability may cause 5xx errors

## How this service works

Global current weather, hourly forecasts, foreign-exchange rates, EVM reads, and deterministic utilities for AI agents. Pay per call with MPP or x402; no API key.

## Output

A JSON object containing the requested latitude, longitude, the number of forecast hours, and a 'forecast' array with hourly weather data points for each hour requested up to 24 hours ahead.
