## 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 suverse-us-freight-road-conditions-api-d08485ef -d '<json body>'
```

Example prompt: Check road conditions for a freight truck driving from 41.8781,-87.6298 (Chicago) to 32.7767,-96.7970 (Dallas) — give me a CLEAR, CAUTION, or SEVERE verdict including any active NWS weather alerts and work zone closures along the corridor.

## When to prefer this

Choose this endpoint when you need a single safety verdict for a US freight or long-haul trucking corridor that combines both real-time weather alerts (NWS) and active work zone / closure data (WZDx) in one call. It is especially valuable when fail-closed behavior and automatic refunds on data failures are important for reliability. Prefer this over general weather APIs when freight-specific road hazards, DOT work zone feeds, and honest coverage gaps matter for the decision. Best suited for US domestic routes where per-state DOT data availability is relevant.

## Known failure modes

- Invalid or unresolvable origin/destination place names — returns an error indicating geocoding failure
- NWS or WZDx feed temporarily unavailable — endpoint fails closed rather than returning stale data, with auto-refund
- Route spans states with no WZDx coverage — disclosed transparently in the per-state coverage field
- Malformed request body — returns 400-level error with schema validation message
- Network timeout on upstream DOT feed sampling — fails closed with auto-refund triggered

## How this service works

CLEAR / CAUTION / SEVERE verdict for any US freight corridor: live NWS alerts sampled along the route + WZDx work zones within 30 km (closures first) from keyless state DOT feeds. Honest per-state coverage disclosure. Origin/destination as lat,lon or place names. Fail-closed, auto-refund.

## Output

A structured response containing a top-level safety verdict (CLEAR, CAUTION, or SEVERE), a list of active NWS weather alerts sampled along the route, WZDx work zone events within 30 km of the corridor (prioritizing closures), and an honest per-state coverage disclosure indicating which states have available DOT feed data.
