## 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 space-weather-brief-llm-digest-61682a3e
```

Example prompt: Give me an LLM-written space weather digest covering the strongest events since January 1, 2025 — I want a narrative summary of what's been going on with solar flares and geomagnetic storms.

## When to prefer this

Choose this endpoint when you need a human-readable, LLM-narrated summary of space weather rather than raw structured alert data. Prefer this over the sibling NOAA SWPC alerts endpoint when the goal is to communicate space weather trends to a non-technical audience or generate a concise briefing. Best for periodic digest use cases (daily/weekly roundups) rather than real-time monitoring.

## Known failure modes

- No significant events in the requested window may yield a minimal or empty brief
- Invalid ISO 8601 datetime format for 'since' parameter returns a validation error
- Payment failure (x402) if USDC balance is insufficient
- Service unavailable if upstream NOAA SWPC data is unreachable
- Very long time windows may produce less focused or overly broad digests

## How this service works

An LLM-written digest of the strongest recent space-weather events.

## Output

Returns a JSON object with a 'brief' field containing an LLM-authored prose summary of the most significant space-weather events in the window, a 'generatedBy' field indicating whether it was LLM or template generated, and 'basedOnChanges' indicating how many underlying events the digest is based on.
