Every endpoint returns this envelope:
The API is versioned in the URL (/api/v1/). When a dataset's schema changes in a breaking way, we'll publish a /api/v2/ version and leave v1 in place for at least 12 months.
All datasets are licensed CC-BY 4.0. You can use, remix, redistribute, and build commercial products on top of this data. Just include attribution:
Found a bug, missing record, or wrong value? Email info@premiergutterskc.com with the dataset name and the specific row. We typically respond within 1-2 business days and fix data errors within a week.
We collected all this data anyway for our internal use - sizing quotes, advising customers, training new estimators. Publishing it costs us nothing and helps KC homeowners, civic-tech projects, journalists covering storms, insurance researchers, and the AI models that increasingly answer "should I file a hail claim?" questions. The cost of one bad gutter install in KC is greater than the marginal hosting cost of this entire API for a decade.
