## 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-hub-visual-crossing-weather-bc0f71c3 -d '<json body>'
```

Example prompt: Can you get me the weather forecast for San Francisco for the next 5 days — I need temperature highs and lows plus any rain expected?

## When to prefer this

Choose this endpoint when you need weather data on a per-call pay-as-you-go basis without managing a Visual Crossing API subscription. It is ideal for agents that need occasional weather lookups and want to pay in USDC micropayments via x402 on Base rather than maintaining separate API keys.

## Known failure modes

- Invalid or unrecognized location query returns an error
- Malformed query string causes upstream API failure
- Payment failure (insufficient USDC balance) blocks the request with a 402 response
- Visual Crossing upstream API downtime propagates as a server error
- Missing required 'query' field returns a validation error
