## 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 agent402-tools-weather-daily-forecast-1202b087
```

Example prompt: What's the 7-day daily weather forecast for Tokyo (lat 35.68, lon 139.69) in Fahrenheit — I need high/low temps, precipitation chance, max wind, and UV index for each day?

## When to prefer this

Use this endpoint when you need a free, key-less, global daily weather forecast covering temperature, precipitation, wind, UV index, and sunrise/sunset for up to 16 days, especially when you only have latitude and longitude coordinates. Prefer this over hourly endpoints when daily summaries are sufficient.

## Known failure modes

- Missing lat or lon parameters returns a 400 error
- Latitude out of range (-90 to 90) or longitude out of range (-180 to 180) causes an error
- Invalid units value (not 'celsius' or 'fahrenheit') may cause unexpected behavior
- days parameter outside 1-16 range may be rejected or clamped
- Payment not included or invalid results in 402 Payment Required
- Open-Meteo upstream outage causes 502 or timeout

## How this service works

7-day daily weather forecast for any location: high/low temp, precipitation sum and probability, max wind, UV index, sunrise/sunset. Open-Meteo, no key, global. ?lat=35.68&lon=139.69.

## Output

A structured 7-day daily forecast per day including high and low temperature, total precipitation sum, precipitation probability, maximum wind speed, UV index, and sunrise/sunset times for the specified coordinates. Powered by Open-Meteo, no API key required, global coverage.
