## 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 ntsb-aviation-accidents-lookup-755d2fb5
```

Example prompt: Can you pull up any NTSB accident records for the Cessna 172 registered as N1330Y — show me up to 10 results from 2020 onward in Texas?

## When to prefer this

Use this endpoint when you need authoritative, ground-truth NTSB aviation accident data — especially for aircraft due-diligence, safety research, insurance underwriting, journalism, or regulatory compliance. It wraps the official NTSB CAROL database with structured filtering by N-number, make/model, location, and date range, making it far faster than scraping the NTSB website directly. Prefer this over generic web search when you need structured, machine-readable accident records with injury data and official report links.

## Known failure modes

- No records found matching the filters — returns empty items array with count 0
- Invalid date format (not YYYY-MM-DD) — likely returns a 400 or empty result
- State code not recognized — may return empty results
- limit outside 1-100 range — may be clamped or rejected
- Payment not received — 402 response requiring USDC payment via x402
- NTSB source temporarily unavailable — upstream data provider outage

## How this service works

Search the NTSB civil aviation accident & incident database (CAROL) — US events from 1962 to present plus selected foreign investigations. Filter by aircraft registration (N-number, partial match), US state (2-letter code or name), make, model, city, and/or event date range (dateFrom/dateTo as YYYY-MM-DD). At least one filter is required. Returns matching events newest-first: NTSB number, event date/type, city/state/country, aircraft registration(s)/make(s)/model(s), highest injury level, onboard & on-ground injury counts, report type/status, and a link to the official NTSB case page. Data: NTSB (U.S. public domain), live. For aviation safety research, fleet/tail-number history, incident due-diligence, and accident-trend analysis.

## Output

Returns a paginated list of NTSB aviation accident records matching the query, each containing the NTSB event number, event date and type, aircraft make/model, registration, city and state, injury counts, highest injury level, report type and status, and a direct URL to the full NTSB CAROL report. Also includes total match count and whether results were truncated.
