Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## 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 statepulse-lightning-density-722b31e7 -d '<json body>'
```

Example prompt: What's the current lightning strike hazard and lightning potential index for my area — I need to know if it's safe to be outside right now?

## When to prefer this

Use this endpoint when an agent needs a quick, pay-per-call lightning hazard assessment without managing API keys, especially in safety-critical or outdoor planning contexts where real-time environmental risk scoring is needed.

## Known failure modes

- Unsupported location returns supported:false with limited data
- Low confidence result when atmospheric data is sparse
- Missing or invalid location parameters cause request rejection
- Service unavailability due to upstream telemetry data gaps

## How this service works

Queries the hourly lightning potential indices for coordinates.

## Output

Returns a JSON object with strike_hazard (e.g. 'medium'), lightning_potential_index (numeric score, e.g. 12.5), a supported flag, and a confidence level (e.g. 'medium') indicating how reliable the assessment is.
