# NHTSA NCAP 5-Star Safety Ratings Lookup

> NHTSA NCAP 5-Star Safety Ratings Lookup is a paid API for AI agents from 2s.io, paid per call via x402, $0.003/call, status unknown (last checked 2026-10-10).

Returns NHTSA 5-Star crash-test ratings for a US vehicle by make, model, and model year, including overall and sub-ratings, rollover probability, safety tech flags, and recall/complaint counts.

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 nhtsa-ncap-5-star-safety-ratings-lookup-cd7d6ecd
```

Example prompt: What are the NHTSA 5-star crash test ratings for the 2022 Honda Accord — including front, side, and rollover scores, plus whether it has forward-collision warning?

## When to prefer this

Use this endpoint when you need authoritative, government-sourced US vehicle safety ratings from NHTSA's NCAP 5-Star program. Prefer this over third-party automotive data APIs when you need official crash-test star ratings, rollover probabilities, and federally tracked recall/complaint/investigation counts. Best for model years 2011 onward where NCAP coverage is strongest.

## Known failure modes

- Vehicle not found / unrecognized make or model returns empty list (not an error)
- Misspelled make or model may return empty list with no match
- Older vehicles (pre-2011 model years) may have sparse or no NCAP data, returning empty list
- Invalid modelYear outside 1949–2099 range rejected by schema validation
- Rate-limit or payment failure returns HTTP 402 requiring valid x402 payment

## How this service works

NHTSA NCAP 5-Star crash-test ratings for a US vehicle by (make, model, modelYear). Returns one item per crash-tested body style with the overall star rating, front/side/rollover sub-ratings, modeled rollover probability, crash-avoidance tech flags (electronic stability control, forward-collision warning, lane-departure warning), and complaint/recall/investigation counts. A vehicle with no crash testing returns an empty list (a valid result, not an error). Backed by NHTSA's public 5-Star Safety Ratings program; data is public-domain US government records.

## Output

Returns a list of objects — one per crash-tested body style — each containing: overall NHTSA star rating (1–5), frontal/side/rollover sub-ratings, modeled rollover probability percentage, boolean flags for electronic stability control, forward-collision warning, and lane-departure warning, plus counts of complaints, recalls, and investigations. Returns an empty list if the vehicle has not been crash-tested (a valid non-error response).
