## 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-insurance-carrier-market-share-profile-a84ad804
```

## When to prefer this

Use this endpoint when you need historical, multi-year P/C insurance market share data for a specific carrier broken down by line of business and/or state, sourced from the authoritative NAIC Market Share Report. Ideal for competitive intelligence, market analysis, or regulatory research on admitted carriers. Prefer this over web scraping or general search when you need structured, time-series ranking and premium data.

## Known failure modes

- Invalid or unknown NAIC code returns empty result or 404
- Unsupported line of business code returns error
- State jurisdiction code not found returns error
- Missing required 'code' parameter returns 400 validation error
- Network timeout or service unavailability returns 5xx error

From the free annual NAIC Market Share Report. $0.10 per query. Docs: https://api.querylines.com/openapi.json

## Output

A structured response containing the carrier's multi-year market share trajectory including annual rank, direct premiums written, market share percentage, and year-over-year change for the specified line of business and jurisdiction, plus any member companies if a group code was provided.
