## 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-weather-api-270113c6
```

Example prompt: What's the current weather in Austin — temperature, humidity, wind speed, and what it feels like outside?

## When to prefer this

Choose this endpoint when you need real-time, point-in-time weather conditions for a specific city and only need current conditions (not forecasts). It is lightweight, costs only $0.001 USDC per call, and returns a clean structured JSON response. Prefer it over general web search for weather when you need machine-readable structured output rather than natural language text.

## Known failure modes

- Unrecognized or misspelled city name may return an error or default to New York
- Network or upstream Open-Meteo outage may result in a timeout or 5xx error
- Very small or ambiguous city names may resolve to the wrong location

## How this service works

Live current weather conditions for any city, sourced from Open-Meteo

## Output

A JSON object with the city name and country, observation timestamp, current weather description (e.g. 'partly cloudy'), temperature in Fahrenheit, feels-like temperature, wind speed in mph, humidity percentage, and the source (open-meteo.com).
