## 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 2s-io-4cc9e0f8
```

Example prompt: Pull the 10 most recent NHTSA consumer complaints for the 2019 Ford F-150 — I want to see if there are any crash or fire flags and how many injuries were reported.

## When to prefer this

Use this endpoint when an agent needs structured, government-sourced vehicle safety complaint data — particularly when researching used car safety history, investigating known issues with a specific make/model/year, or checking for crash/fire/injury patterns. Prefer over web scraping NHTSA directly because this returns pre-parsed, structured JSON with flags and counts ready for analysis. Best for automotive safety research, pre-purchase due diligence, and regulatory compliance checks.

## Known failure modes

- Unknown make/model/year combination returns empty results array
- Missing required query param (make, model, or modelYear) returns 400 validation error
- modelYear outside 1949–2099 range rejected with validation error
- limit outside 1–100 range rejected with validation error
- NHTSA upstream unavailable may return 502 or timeout
- Payment failure (x402) prevents access if USDC balance insufficient

## How this service works

NHTSA consumer complaints for a US vehicle by (make, model, modelYear). Returns the top N records (newest-filed first) with ODI number, affected component, plain-English summary, crash/fire flags, injury and death counts, partial VIN, and incident + filing dates. Backed by NHTSA's public complaints database; data is public-domain US government records.

## Output

An array of up to N complaint records (default 25, max 100), sorted newest-filed first. Each record includes: ODI number, affected vehicle component, plain-English complaint summary, boolean crash and fire flags, injury and death counts, partial VIN, and both the incident date and the NHTSA filing date. Data is sourced from NHTSA's public-domain complaints database.
