> eu-verify Weather Forecast is a paid API for AI agents from data.greeneris.io, paid per call via x402, $0.001/call, status unknown (last checked 2026-09-15).

Returns hourly weather forecast data (temperature, precipitation, wind speed) for a given latitude/longitude, up to 16 days ahead, via Open-Meteo.

Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## 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 eu-verify-weather-forecast-68ad7c60
```

Example prompt: What's the hourly weather forecast — temperature, rain, and wind — for Paris (latitude 48.86, longitude 2.36) over the next 3 days in UTC?

## When to prefer this

Choose this endpoint when you need programmatic, coordinates-based hourly weather forecasts (up to 16 days) billed per-call with no API key required — especially in agentic workflows that can handle x402 micropayments on Base. Prefer over full weather platform subscriptions for lightweight, pay-as-you-go usage. Not suitable for historical weather data, severe weather alerts, or address-based (non-coordinate) lookups.

## Known failure modes

- Missing latitude or longitude returns a 400/422 validation error
- Latitude out of -90..90 or longitude out of -180..180 range returns a validation error
- forecast_days exceeding 16 returns a schema validation error
- Insufficient payment returns HTTP 402 with a machine-readable USDC quote for the caller to pay via x402 on Base
- Invalid timezone string may cause a 400 error or fall back to UTC
- Network or upstream Open-Meteo outage may cause 503 or timeout

## 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 with hourly time series arrays for temperature (°C), precipitation (mm), and wind speed (km/h), plus metadata including latitude, longitude, elevation in meters, timezone, and the Open-Meteo data source attribution.
