## 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 naic-market-share-carrier-footprint-lookup-0f2171d5
```

Example prompt: Show me Travelers Group's (NAIC code 5765) market footprint across all U.S. states for private passenger auto insurance in 2022 — I want to see their rank, direct premiums written, market share, and year-over-year change in each state.

## When to prefer this

Use this endpoint when you need a single carrier's state-by-state competitive positioning from official NAIC data, including premium volume, market share rank, and year-over-year trends. Prefer this over general web searches when you need structured, authoritative NAIC figures. Best for competitive intelligence, regulatory research, or market entry analysis for a specific carrier across multiple states.

## Known failure modes

- Invalid or unknown NAIC code returns empty results or 404
- Carrier not in top 10 for a state means that state is absent from results
- Requested year not yet loaded returns an error or defaults to latest available
- Invalid line of business code returns a validation error
- States parameter with unrecognized jurisdiction codes may be silently ignored or return an error
- Payment failure (x402) blocks the query entirely

## How this service works

Compare one P/C insurance carrier's market position across U.S. states for a line of business and year: per-state rank, direct premiums written, market share, and year-over-year change, plus a countrywide reference row. From the free annual NAIC Market Share Report -- top-10-per-jurisdiction truncation applies. $0.50 per query. Docs: https://api.querylines.com/openapi.json

## Output

A list of rows — one per U.S. state/jurisdiction where the carrier appears in the NAIC top-10, plus a countrywide summary row — each containing: state code, carrier rank in that state, direct premiums written, market share percentage, and year-over-year change. Note: top-10-per-jurisdiction truncation means carriers ranked 11th or lower in a state will not appear for that state.
