## 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 tollkit-weather-forecast-7b6d7dd3 -d '<json body>'
```

Example prompt: What's the weather going to be like at 38.98 latitude, -76.49 longitude for the next 7 periods — give me a 12-hour forecast breakdown?

## When to prefer this

Choose this endpoint when you need a quick, no-signup weather forecast and can pay micro-amounts per call in USDC via x402. Ideal for agents that need weather data on demand without managing API keys or subscriptions. Best suited for US addresses or precise coordinate-based lookups with up to 14 12-hour forecast periods.

## Known failure modes

- Invalid or out-of-range latitude/longitude values return an error
- Address cannot be geocoded or resolved returns an error
- Periods value outside 1–14 range is rejected
- Payment not included or insufficient USDC amount results in 402 Payment Required response
- Network or upstream weather data provider unavailability causes 5xx errors

## How this service works

Pay-per-call product page extraction. No account, no API key: pay in-band with x402 in USDC on Base or Solana.

## Output

A list of up to 14 12-hour forecast periods for the specified location, including weather conditions and related meteorological data for each period. Response is keyed by the requested latitude/longitude or resolved address coordinates.
