## 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 agentindex-x402-weather-bb1ff578
```

Example prompt: What's the current weather and daily forecast for Paris? I need the temperature, humidity, wind speed, and conditions for the next few days.

## When to prefer this

Choose this endpoint when you need live current conditions plus a multi-day daily forecast in a single pay-per-call request without a subscription, especially in agentic workflows that already operate on Base/USDC via the x402 micropayment protocol. Prefer it over free-tier weather APIs when you need reliable uptime with per-call billing and no API key management.

## Known failure modes

- Missing both city and lat/lon parameters — returns 400 or empty result
- Invalid city name that cannot be geocoded — may return error or empty location
- Payment failure on Base network (insufficient USDC balance) — 402 response with payment required details
- Network timeout or upstream weather provider outage — 503 or timeout error
- Ambiguous city name (e.g. 'Springfield') — may resolve to unexpected location

## How this service works

Current weather and a 3-day forecast for any city or lat/lon - temperature, humidity, wind, conditions. No account, no API key. Try GET /weather/sample.

## Output

Returns a JSON object with three sections: (1) location metadata (name, country, lat/lon, timezone), (2) current conditions (temperature in Celsius, humidity %, wind speed km/h, weather code and text description, timestamp), and (3) an array of daily forecasts (date, max/min temperature in Celsius, precipitation sum in mm, weather code and conditions string).
