## 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 datavault-weather-lookup-e5468518 -d '<json body>'
```

Example prompt: What's the current weather in Austin, Texas right now? Use coordinates 30.2672, -97.7431 if that helps.

## When to prefer this

Use this endpoint when you need live weather data for a specific city or coordinate and want a pay-per-call model with no subscription commitment. Prefer this over subscription weather APIs for low-frequency or ad-hoc queries billed in USDC on Base.

## Known failure modes

- City name not recognized or ambiguous — returns error or empty data
- Invalid latitude/longitude values — may return error response
- External weather data provider unavailable — success false with empty data
- Missing all location inputs — request rejected
- Rate limiting or payment failure — 402 response
