## 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 x402-data-bazaar-vercel-app-b03cb7f8
```

Example prompt: Can you pull the 7-day weather forecast for latitude 40.7, longitude -74.0 — I need daily high and low temps in Fahrenheit, chance of rain, and the general condition for each day?

## When to prefer this

Choose this endpoint when you need structured multi-day (1–16 day) daily weather forecasts keyed to precise lat/lon coordinates, especially when you need temperature ranges in Fahrenheit alongside precipitation and wind data per day. Prefer it over current-conditions endpoints when planning ahead, and over weather-decision-brief endpoints when you want raw forecast data rather than interpreted recommendations.

## Known failure modes

- Missing lat or lon parameter returns an error — both are required
- Invalid or out-of-range coordinate values may return no data or an error from the upstream provider
- days value outside 1–16 range may be clamped or return an error
- Network or upstream Open-Meteo API outage causes a failed response
- Malformed query string (e.g. non-numeric lat/lon) returns a validation error

## How this service works

Daily weather forecast (1-16 days) for any lat/lon -- high/low temps (F), precipitation, chance of rain, max wind, condition. Query: ?lat=40.7&lon=-74.0&days=7. If omitted, defaults to a NYC sample location.

## Output

An array of daily forecast objects each containing the date, low and high temperatures in Fahrenheit, weather condition label (e.g. 'Overcast', 'Clear'), precipitation amount, chance of rain, and max wind speed, plus the timezone for the queried location and a success flag.
