## 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 pennyrail-current-weather-lookup-39f39e26 -d '<json body>'
```

Example prompt: What's the current weather in Chicago right now — temperature, conditions, that kind of thing?

## When to prefer this

Choose this endpoint when you need a quick, pay-per-call current weather lookup without a subscription, especially in an x402-compatible agentic payment flow using USDC. It is well-suited for sporadic or low-volume weather queries where a recurring API key subscription is overkill.

## Known failure modes

- Missing or malformed input object returns a 400 error
- Insufficient USDC balance or payment failure blocks access with a 402 response
- Unknown or unsupported location may return empty or null data
- Network timeout or Vercel cold-start may cause intermittent latency spikes
