## 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 weatherxm-agent-api-7-day-weather-forecast-5a5413e6
```

Example prompt: What's the 7-day weather forecast for Athens, Greece (37.98°N, 23.73°E) in metric units, using the Europe/Athens timezone? I want hourly and daily breakdowns including temperature, precipitation, and wind.

## When to prefer this

Choose this endpoint when you need structured, machine-readable multi-day (up to 7 days) weather forecast data keyed by geographic coordinates, especially when you require both hourly and daily granularity in a single call. Prefer this over current-conditions or historical endpoints when forward-looking planning is the goal. Well-suited for automation pipelines, travel planning, agricultural scheduling, or any agent workflow that needs upcoming weather at a precise lat/lon.

## Known failure modes

- Missing required lat or lon parameters returns a 400 error
- Latitude out of range (-90 to 90) or longitude out of range (-180 to 180) returns validation error
- Invalid or unrecognized timezone string may cause timezone parsing error
- Payment failure (x402 protocol) results in 402 Payment Required with no forecast data
- Service unavailability or upstream data gap may return 503 or empty forecast arrays
