# Free sample: statewide all-lines series, latest 13 periods

`GET /v1/premium/sample`

- Auth: none declared

Free -- the teaser for /v1/premium. Statewide all-lines only, capped at the latest 13 periods. Granularity follows what the state publishes: month (FL, TX, CA), half (IL), or year (NY, WA); check the `granularity` field rather than assuming month. For annual states with more history than the window shows, `history` carries the first and latest priced periods and the growth multiple across the whole series. Line/county/insurer detail, full history, and cross-state comparison are paid.

## Query parameters

- `state` string
