## 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 saylor-innovations-outdoor-trip-brief-c0c45d42
```

Example prompt: Pull me a full trip brief for hiking near lat 39.7392, lon -104.9903 — give me a 5-day activity-scored forecast, river gauge status, any wildfire alerts, and a pack list.

## When to prefer this

Choose this endpoint when you need a single aggregated outdoor-trip intelligence call covering weather scoring, hydrology, wildfire risk, and packing recommendations for a US location — rather than calling separate weather, river, and fire APIs independently. Ideal for AI agents building trip-planning workflows where multiple hazard signals need to be synthesized into a go/no-go recommendation for a specific outdoor activity.

## Known failure modes

- Missing required lat/lon parameters returns a 400 error
- Non-US coordinates may return no data or empty results since the service is US-focused
- Invalid activity type enum value may fall back to 'general' or return an error
- Date outside the forecast range returns no hourly detail
- days value outside 1-7 range may be clamped or rejected
- River/wildfire data may be sparse or absent in regions with limited gauge/sensor coverage

## How this service works

Outdoor trip brief - activity-scored forecast, best window, river gauges and flood stage, wildfires, sun/moon, pack list

## Output

A JSON object containing: a location descriptor, an overall verdict with score and reasons, a day-by-day (and optionally hourly) activity-scored forecast array, active weather alerts, river gauge readings with flood stage status, wildfire incidents within the search radius, sun/moon rise/set times, a recommended best time window, a suggested pack list, data sources used, items not covered, and a disclaimer.
