## 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 openweather-5-day-forecast-via-locus-x402-230b6167 -d '<json body>'
```

## When to prefer this

Choose this endpoint when you need multi-day (up to 5-day) forecast data in 3-hour increments for a specific geographic coordinate, especially when you need structured JSON output with granular timestamps and support for multiple unit systems and languages. Prefer over current-conditions endpoints when planning ahead is required.
