## 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 weather-alerts-brief-llm-digest-52e058b1
```

Example prompt: Give me an LLM-written digest of the most urgent active weather threats since yesterday — just the serious ones I need to know about right now.

## When to prefer this

Use this endpoint when you need a human-readable, concise narrative summary of weather threats rather than raw structured alert data. It is ideal for agents that need to communicate weather risk to end users in plain language, or when you want an interpreted digest rather than a list of raw alerts. Prefer this over raw weather data APIs when brevity and readability matter more than structured querying.

## Known failure modes

- No recent weather alerts in window — returns empty or minimal brief
- Invalid date-time format for 'since' parameter — likely returns 400 error
- Payment not completed (x402) — returns 402 Payment Required
- LLM generation failure — may fall back to template-based output (generatedBy: template)
- Network timeout if LLM generation is slow

## How this service works

An LLM-written digest of the most urgent active weather threats.

## Output

A natural-language brief narrative (LLM-written) summarizing the most serious active weather threats, along with metadata indicating whether it was generated by LLM or template and how many underlying alert changes it was based on.
