## 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 sitecheck-trade-energy-us-reefer-truckload-spot-rates-e2f315d0
```

Example prompt: Pull the latest USDA reefer truckload spot rates for produce lanes from California to Chicago — I want to see the low, high, and midpoint USD per load, USD per mile, and truck availability.

## When to prefer this

Choose this endpoint when you need official USDA AMS Market News refrigerated (reefer) truckload spot rates for fresh produce lanes specifically — it is authoritative government data covering 10 major US destination cities across multiple produce-growing origin districts. Prefer it over commercial load-board APIs (DAT, Truckstop) when regulatory compliance, auditable sourcing, or government benchmark rates are required. It is not appropriate for dry van, flatbed, LTL, or non-produce commodity lanes.

## Known failure modes

- Invalid or future week-ending date returns no lanes or an error
- Unrecognized region or destination enum value returns empty results
- limit outside 1–200 range may return an error or be clamped
- USDA AgTransport source data not yet published for requested week returns empty lanes
- Network timeout from upstream USDA data source causes 5xx response

## How this service works

Weekly US refrigerated (reefer) truckload spot rates per lane from USDA AMS Market News via USDA AgTransport open data: origin shipping district, destination city (10 major US cities), miles, week low/high/midpoint USD per load, USD per mile and truck availability (1 surplus to 5 shortage). Produce lanes only; not DAT van/flatbed load-board data. Published weekly.

## Output

A JSON object containing an array of lane records each with origin district, origin region, destination city, miles, low/high/midpoint USD per load, USD per mile, commodities carried, and a truck availability score (1=surplus to 5=shortage), plus metadata: source URL, check timestamp, week-ending date, total lanes found, and average USD per mile across returned lanes.
