# QueryLines E&S Insurer Eligibility Lookup (NAIC IID)

> QueryLines E&S Insurer Eligibility Lookup (NAIC IID) is a paid API for AI agents from api.querylines.com, paid per call via x402, $0.1/call, status unknown (last checked 2026-09-14).

Checks whether a surplus lines / E&S insurer is eligible to write business nationwide under NRRA by looking up the NAIC Quarterly Listing of Alien Insurers (IID), returning match status, entity details, and any state-specific restrictions.

## 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 querylines-e-s-insurer-eligibility-lookup-naic-iid-5e31fb68
```

Example prompt: Can you check if 'Markel Bermuda Limited' with NAIC IID alien ID AA-1344102 is eligible to write surplus lines business, and flag any state-specific restrictions for California?

## When to prefer this

Use this endpoint when you need to verify whether a specific non-admitted (surplus lines / E&S) alien insurer or Lloyd's syndicate is eligible to write business under the NRRA nationwide framework, especially before placing a policy or conducting compliance checks. Prefer this over state surplus lines stamping office lookups when you need a single authoritative NAIC IID source covering all states. Use the list mode with changes_since to monitor roster changes over time.

## Known failure modes

- Unknown insurer returns match: null rather than a 404 — agent must check for null match
- Invalid alien ID format returns a validation error
- state parameter must be a valid two-letter code or the request is rejected
- changes_since must match YYYY-MM pattern or the request fails
- Payment required (402) if x402 payment header is missing or insufficient
- limit out of range 1-500 returns a parameter error

## How this service works

Surplus lines / E&S insurer eligibility from the NAIC Quarterly Listing of Alien Insurers (IID) -- nationwide under NRRA. Look up an insurer by name or alien ID (unknown insurer returns match: null, not a 404), or list the current roster of alien companies and Lloyd's syndicates with recent additions/removals. State-specific restrictions surface as data, never read as plainly eligible. $0.10 per query. Free sample: /v1/eligibility/sample. Docs: https://api.querylines.com/openapi.json

## Output

Returns a match object (null if insurer not found, never a 404) with the insurer's alien ID, name, entity type (alien_company or lloyds_syndicate), eligibility status, and any state-specific restrictions surfaced as data fields. In list mode, returns a paginated roster of all eligible alien companies and Lloyd's syndicates with additions and removals since a requested date.
