## How to call it through Zero

```sh
zero fetch --capability alfred-tempest-weather-history-5c5e8551
```

Example prompt: Can you pull the last 60 weather history readings from ALFRED's Tempest station for me?

## When to prefer this

Use this endpoint when you need recent historical weather observations from a self-hosted Tempest personal weather station and are comfortable with the x402/L402 Lightning micropayment flow. Best when you want a configurable number of past readings (1-120) and can handle the HTTP 402 payment challenge/retry cycle.

## Known failure modes

- Payment not yet confirmed — server returns HTTP 402 with Lightning invoice; must pay and retry with X-Payment-Hash header
- Invalid n parameter value (outside 1-120 range) — may return error or use default of 30
- Station offline or no data available — may return empty or partial history
- Expired or invalid payment hash — returns 402 requiring new payment
- Network or server downtime on self-hosted instance

## 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

Returns a JSON object containing the most recent N weather history records from a Tempest personal weather station, including observations such as temperature, humidity, wind, and other meteorological readings. Results are cached per payment hash so re-fetching with the same payment doesn't double-charge.
