## 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 micro-data-api-factory-weather-forecast-91aa12d1
```

Example prompt: What's the weather forecast for the next 5 days in Chicago? Give me the full daily breakdown.

## When to prefer this

Use this endpoint when you need a lightweight, AI-readable JSON weather forecast accessible via a simple GET request with micropayment (x402 protocol), especially in agentic workflows where you want structured forecast data without OAuth or API key setup. Prefer when location can be expressed as lat/lon or city name and you need 1–N days of forecast data.

## Known failure modes

- Missing or invalid lat/lon and city — returns error if no location is specified
- Invalid city name that cannot be resolved to coordinates
- Days parameter out of supported range — may cap or error
- Cloudflare Worker cold start or downtime — upstream availability issues
- x402 payment not processed — request blocked without valid micropayment
