## Changelog

### 2026-09-23

*Fixes*

- Historical permit searches with only an end date now cover the 30 days ending on that date, rather than silently searching a later window.
- API runs that omit the maximum now save at most 20 permits by default, matching the Console input and documentation.

### 2026-07-15

*Features*

- Search Chicago's official building permit dataset by issue date, permit status/type, work/review type, ward, community area, address, project cost, and contact details.
- Look up an exact permit number and export normalized project, fee, location, and typed owner/applicant/designer/contractor data.
- Save query provenance and direct source links with every permit for auditable recurring lead and construction-intelligence workflows.

*Reliability*

- Uses the City of Chicago's public Socrata API with stable pagination, bounded retries, rate-limit backoff, and no proxy or login dependency.
