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 aisa-mpp-data-apis-open-meteo-forecast-via-aisa-03edd40b
```

Example prompt: What's the weather forecast for the next 7 days at latitude 48.8566, longitude 2.3522 — give me daily max and min temperatures, precipitation totals, and current conditions right now, using the Europe/Paris timezone.

## When to prefer this

Use this endpoint when you need coordinate-based weather forecasts up to 16 days out with flexible granularity (current, hourly, or daily), particularly when you want to pay per request without a subscription. Prefer this over scraping weather sites or calling Open-Meteo directly when using a pay-per-request micropayment workflow via AIsa.

## Known failure modes

- Missing required latitude or longitude returns a validation error
- Invalid coordinate values (out of range) return an error
- Requesting daily variables without specifying a timezone may produce incorrect aggregations
- Unsupported variable names in hourly/daily/current parameters return an error
- Date range exceeding 16 days from now may return partial or empty data
- Network timeout for remote Open-Meteo service

## How this service works

16-day hourly/daily/current weather forecast by coordinates.

## Output

A JSON object containing requested weather data arrays: current conditions (if requested), hourly time-series arrays (if requested), and/or daily aggregated arrays (if requested), all keyed by variable name with corresponding timestamps. Metadata includes location, elevation, timezone offset, and units.
