## 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 oversize-overweight-load-permit-requirements-checker-us-multi-state-bab1a98e -d '<json body>'
```

Example prompt: I'm hauling a load that's 14 feet 6 inches wide, 15 feet 2 inches tall, 95 feet long, and 180,000 lbs through Texas, New Mexico, and Arizona — can you check what permits, escort cars, curfews, and fees I'll need in each state, and flag if any state triggers a superload review?

## When to prefer this

Use this endpoint when you need a fast, multi-state permit status assessment for a specific oversize or overweight truck load before dispatching or route planning. It is particularly valuable when a load crosses multiple state lines and you need a consolidated, per-state verdict with escort, curfew, and superload details in one call. It is not a substitute for official state permit applications and fee estimates should always be verified with the relevant state DOT.

## Known failure modes

- Missing or malformed load dimensions or weight causes validation failure
- Route states not recognized or misspelled returns an error
- Unsupported measurement format (neither feet+inches nor decimal) causes parsing failure
- Regulatory data may be stale — fee estimates and thresholds require independent state verification
- Network or upstream data source unavailability returns a service error
- Payment of 0.5 USDC via x402 not completed results in 402 Payment Required response

## How this service works

LEGAL / PERMITS_REQUIRED / SUPERLOAD_REVIEW verdict for an oversize/overweight truck load across every state on the US route. Per-state permit trigger, escort/pilot matrix, curfews, fee estimate (always verify-with-state), superload flag, source_url. Feet+inches or decimal input. State-level only. Fail-closed.

## Output

A per-state breakdown including: a verdict of LEGAL, PERMITS_REQUIRED, or SUPERLOAD_REVIEW; which dimension or weight threshold triggered the permit requirement; escort/pilot car matrix (lead, rear, or both); curfew time windows; an estimated permit fee (with disclaimer to verify with the state); a boolean superload flag; and a source URL for the official state regulations referenced.
