# Open-Meteo Hourly Weather Forecast

> Open-Meteo Hourly Weather Forecast is a paid API for AI agents from x402-datashop-production.up.railway.app, paid per call via x402, $0.001/call, status unknown (last checked 2026-09-13).

Returns hourly weather forecast data (temperature, precipitation, wind, and ~80 variables) for any lat/lon on Earth for 1–16 days, sourced from ECMWF/GFS/ICON model blends

## 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 open-meteo-hourly-weather-forecast-fef21d72
```

Example prompt: Can you get me an hourly weather forecast for Paris (latitude 48.8566, longitude 2.3522) for the next 2 days, including temperature, precipitation, and wind speed, with times in the Europe/Paris timezone?

## When to prefer this

Use this endpoint when you need structured, machine-readable hourly weather forecast data for any precise geographic coordinate on Earth, especially when you need multi-day forecasts (up to 16 days), a wide range of meteorological variables (~80 available), or model-blended accuracy from ECMWF/GFS/ICON. Prefer over general weather APIs when you need programmatic access to raw time-series arrays with ISO 8601 timestamps and explicit units.

## Known failure modes

- Missing latitude or longitude returns 400 Bad Request
- Latitude outside -90..90 or longitude outside -180..180 returns validation error
- forecast_days exceeding 16 returns a validation error
- Invalid hourly variable name returns an error from the upstream Open-Meteo API
- Unknown IANA timezone string may cause an error or fall back to UTC
- Payment not provided or invalid x402 payment header returns 402 Payment Required

## How this service works

Hourly weather forecast for any point on Earth from Open-Meteo (blend of ECMWF/GFS/ICON models, refreshed hourly; data CC-BY 4.0). Query: ?latitude=48.8566&longitude=2.3522&hourly=temperature_2m,precipitation,wind_speed_10m&forecast_days=2 (1-16 days, ~80 hourly variables available, optional daily= aggregates and timezone=auto). ISO 8601 time arrays + units. 15 min cache.

## Output

A JSON object containing ISO 8601 time arrays and corresponding arrays of hourly values for each requested variable (e.g. temperature_2m in °C, precipitation in mm, wind_speed_10m in km/h), plus unit metadata. Optional daily aggregates are included if requested. Data is cached for 15 minutes and sourced from a blend of ECMWF, GFS, and ICON numerical weather models.
