Endpoint
GEThttps://api.querylines.com/v1/insurersWhen to prefer
Use this endpoint when you need a ranked list of E&S insurers by premium for a specific U.S. state and time period. Ideal for insurance market analysis, competitive intelligence on non-admitted carriers, or researching surplus lines market concentration. Prefer this over sibling endpoints when you need a point-in-time ranking rather than a time series or year-over-year comparison.
