## 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 alfred-x402-tempest-live-weather-service-b8b26089
```

Example prompt: Can you grab the current live weather conditions from ALFRED's Tempest station and give me the results in JSON format?

## When to prefer this

Choose this endpoint when you need real-time personal weather station data from a WeatherFlow Tempest device via a pay-per-call Lightning/x402 micropayment model. Prefer this over public weather APIs when you want hyperlocal, station-specific readings rather than interpolated regional forecasts, and when your agent workflow supports the x402/L402 payment-retry handshake.

## Known failure modes

- HTTP 402 returned with Lightning invoice if payment not yet made — agent must pay and retry with X-Payment-Hash header
- Invalid or expired payment hash returns 402 again
- Station offline or no recent Tempest data returns an error or stale payload
- Malformed format parameter may default to JSON silently
- Network timeout on self-hosted infrastructure

## How this service works

Self-hosted personal-assistant paid tools via Lightning. Uses x402-shaped protocol (L402 lineage): HTTP 402 with a Lightning invoice in the response body + WWW-Authenticate header, retry with X-Payment-Hash: <hex> once paid. Results cached per payment_hash so legitimate retries don't cost twice.

## Output

A JSON object containing live weather readings from a self-hosted WeatherFlow Tempest personal weather station, including fields such as temperature, humidity, wind speed/direction, and atmospheric pressure. Results are cached per payment hash so retrying after a successful payment returns the same data without an additional charge.
