Technical details
Endpoint
GEThttps://api.querylines.com/v1/premium/summaryWhen to prefer
Use this endpoint when you need a concise year-over-year snapshot of E&S insurance premium and policy counts for a single U.S. state and year, including prior-year comparison and percent change. Prefer this over the time-series endpoint when you only need a single-year summary with YoY delta rather than a full historical series, and over the comparison endpoint when you are not cross-comparing multiple states simultaneously.
Side effects
- Missing or invalid state code returns a 400 error
- Unsupported or future year with no data returns a 404 or empty result
- Invalid year format (non-integer) returns a validation error
- State with no stamping office data may return empty or null fields
- Payment failure (x402) if USDC balance is insufficient
