## 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-complaints-lookup-d2879321
```

Example prompt: Pull up the NHTSA owner complaints for a 2020 Honda Accord — give me the top 10 incidents with their dates, components involved, and whether any involved a crash or fire.

## When to prefer this

Use this endpoint when you need official US NHTSA consumer complaint data for a specific vehicle (make + model + year). Ideal for pre-purchase due diligence, safety research, or identifying recurring component failures reported by real owners. Prefer this over general web search when you need structured, filterable complaint data with crash/fire/injury flags directly from the NHTSA database.

## Known failure modes

- Invalid or unrecognized vehicle make/model returns empty results or error
- Year outside supported range (1950–2100) returns validation error
- NHTSA upstream API unavailable causes service error
- Misspelled make or model returns no results
- Limit parameter outside 1–50 range causes validation error

## How this service works

US NHTSA owner-filed vehicle complaints for a make, model and model year: incident date, components, summary, crash/fire flags and injury counts. Complaints are unverified owner reports; the total count is NHTSA's, the returned list is a slice.

## Output

Returns a list of owner-filed NHTSA complaints (up to the requested limit, default 10) for the specified make/model/year, each including incident date, affected components, complaint summary text, crash flag, fire flag, and injury count. Also includes the total complaint count as reported by NHTSA.
