## 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-weather-api-23025838
```

Example prompt: What's the current weather in Tokyo right now — temperature, conditions, all of it?

## When to prefer this

Choose this endpoint when you need lightweight, real-time current weather conditions for a city by name and are operating in an x402 micropayment context. It is ideal for agents that need quick weather lookups without complex setup, leveraging Open-Meteo as a reliable free data source behind a simple pay-per-call interface. Prefer alternatives if you need forecast data, historical weather, or weather by coordinates rather than city name.

## Known failure modes

- Invalid or unrecognized city name returns an error or defaults to New York
- City parameter omitted defaults to New York rather than returning an error
- Ambiguous city names (e.g. 'Springfield') may resolve to an unexpected location
- Open-Meteo upstream downtime may cause request failures
- Payment of $0.01 USDC required per call; missing payment results in 402 response
