## 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-apis-weather-data-pay-per-request-491e0591
```

Example prompt: What's the current weather in Austin, Texas? Just pay the per-request fee and give me temperature and conditions — no API key setup.

## When to prefer this

Choose this endpoint when your AI agent needs weather data without going through API key registration or account setup, and you are comfortable with small per-call USDC micropayments via the x402 protocol. Ideal for low-frequency, on-demand weather lookups in agent workflows where frictionless access matters more than bulk pricing.

## Known failure modes

- Payment not included or insufficient — returns HTTP 402 with payment requirements
- Invalid or unrecognized city name — may return empty or error response
- Missing both city and lat/lon parameters — likely returns a 400 bad request
- Network or Vercel hosting downtime — 503 or timeout
- Invalid coordinate values — may produce unexpected results or errors
