## 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 nhtsa-vehicle-safety-ratings-4d4e565b
```

Example prompt: What are the NHTSA five-star crash safety ratings for the 2022 Honda Accord — overall, frontal, side, and rollover — and how many recalls and complaints does it have?

## When to prefer this

Use this endpoint when you need authoritative US government NCAP crash safety ratings and recall/complaint data for a specific vehicle. Prefer this over generic car review APIs when official NHTSA star ratings are required, such as for compliance reporting, pre-purchase safety analysis, or fleet management decisions.

## Known failure modes

- Vehicle not found in NHTSA database for the given model year/make/model combination — returns empty or error response
- Misspelled make or model name results in no match
- Model year out of range of NHTSA data coverage
- API returns 402 if payment header is missing or invalid

## How this service works

## Output

Returns the NCAP five-star crash safety ratings broken down by overall, frontal, side, and rollover categories for the specified vehicle, along with counts of recalls, consumer complaints, and active investigations on record with NHTSA.
