Looks up NHTSA vehicle safety complaints by make, model, and model year, returning complaint summaries, affected components, and aggregate statistics.

Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## 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 oneshot-agent-api-vehicle-complaints-lookup-910e9f4a -d '<json body>'
```

Example prompt: Can you pull up the 5 most recent NHTSA safety complaints for the 2019 Fiat 124 Spider and tell me which components are most affected?

## When to prefer this

Use this endpoint when you need structured, official NHTSA consumer complaint data for a specific vehicle make, model, and year — especially for pre-purchase research, safety audits, or identifying recurring defect patterns by component. Prefer this over generic web search when you need aggregated statistics (totals, component breakdowns) and individual complaint text in a machine-readable format, and when paying per-call via x402/USDC is acceptable.

## Known failure modes

- No complaints found for an obscure or very new vehicle — returns empty complaints array
- Invalid or unrecognized make/model combination — may return zero results or error
- Model year outside supported range (pre-1950 or beyond next year) — validation error
- Payment failure over x402 — 402 response if USDC payment not provided
- Rate limiting or upstream NHTSA API unavailability — 5xx error

## How this service works

Summarize the safety complaints owners filed for a vehicle make, model and model year, with the newest ones.

## Output

Returns the vehicle make, model, and model year along with aggregate statistics (total complaints, fires, crashes, deaths, injuries), a list of individual complaints (each with ID, summary, incident date, filed date, components involved, crash/fire/injury flags), and a breakdown of components sorted by complaint frequency.
