## 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 klymax402-weather-api-fbc7b16f
```

Example prompt: What's the current weather and forecast in Berlin? I can also give you the coordinates — latitude 52.52, longitude 13.40 — if that's easier.

## When to prefer this

Choose this endpoint when you need quick, pay-per-call weather lookups without managing API keys — ideal for AI agents that need weather data infrequently or across diverse workflows, and are already using USDC on Base for micropayments via the x402 protocol.

## Known failure modes

- City name not recognized or ambiguous — may return wrong location or error
- Latitude/longitude out of valid range (-90 to 90 / -180 to 180) — validation error
- Missing both city and coordinates — request rejected
- Payment failure via x402/USDC — 402 response returned
- Upstream weather data provider outage — may return stale or empty data
