## 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 24klabs-weather-forecast-api-9c4bcf5f -d '<json body>'
```

Example prompt: Can you pull the weather forecast for the next 7 days at latitude 40.7128, longitude -74.0060 — I need daily highs, lows, precipitation, and general conditions?

## When to prefer this

Choose this endpoint when you need a structured multi-day daily weather forecast (highs, lows, precipitation, conditions) for any arbitrary coordinates globally. It wraps Open-Meteo's free-tier data behind a simple paid API call, making it ideal for agents that need weather data without managing Open-Meteo API keys directly. Prefer this over current-conditions endpoints when planning ahead over multiple days.

## Known failure modes

- Invalid or out-of-range latitude/longitude returns an error
- Requesting too many forecast days beyond available range returns an error
- Network or upstream Open-Meteo API outage causes failure
- Missing required lat/lon parameters results in a bad request error

## How this service works

Daily high/low, precipitation, and conditions for the next N days at any lat/lon (Open-Meteo).

## Output

Returns a day-by-day forecast array covering the requested number of days, with each entry containing the daily maximum temperature, daily minimum temperature, precipitation amount, and a general weather condition description for the given latitude/longitude location.
