## 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-brief-25a5676a -d '<json body>'
```

Example prompt: Give me a full weather briefing for Paris — current conditions, the 7-day forecast, and the air quality index. The coordinates are latitude 48.8566 and longitude 2.3522.

## When to prefer this

Use this endpoint when you need current conditions, multi-day forecast, and air quality data all at once for a given location without making three separate API calls. Ideal for agent workflows that need a complete weather picture in one step and want to minimize cost and latency via a single bundled payment.

## Known failure modes

- Invalid or out-of-range latitude/longitude returns an error or empty result
- Missing lat or lon parameter causes a 400 bad request
- x402 payment failure or insufficient balance prevents execution
- Upstream weather data provider outage results in a 502 or timeout
- Coordinates in remote ocean areas may return limited data

## How this service works

Bundled execution of the Weather briefing workflow - Full weather briefing for a location: current conditions, 7-day forecast, and air quality index in one pass. One x402 payment runs 3 underlying tools (weather-current, weather-daily, weather-air-quality); partial-success per step.

## Output

A combined payload containing current weather conditions (temperature, humidity, wind, etc.), a 7-day daily forecast, and an air quality index (AQI) for the specified coordinates — all returned in a single response from one $0.05 USDC x402 payment.
