## 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-weather-api-c5871e73 -d '<json body>'
```

Example prompt: What's the current weather in San Francisco — temperature, conditions, and humidity?

## When to prefer this

Choose this endpoint when you need programmatic weather data access with per-call micropayment billing on Base (USDC), avoiding subscription API key management. Ideal for AI agents that need on-demand weather lookups without pre-negotiated API keys, or when building on the x402 payment rail for pay-as-you-go access.

## Known failure modes

- Invalid or unrecognized location query returns an error or empty data
- Payment failure (402) if x402 micropayment is not properly attached
- Upstream WeatherAPI.com outage results in proxy error
- Malformed query string causes upstream API rejection
- Rate limiting or quota exhaustion on the underlying WeatherAPI.com account
