}About the cookcountyil.gov API
The Cook County IL API provides 4 endpoints covering public records from Cook County government, including property tax records, civil and domestic court cases, code violation lookups, and department contact information. The get_department_contacts endpoint returns agency names, URLs, phone numbers, email addresses, and director details, while search_court_cases lets you query civil, law, chancery, and domestic relations divisions by case number.
Department Contacts and Property Tax
The get_department_contacts endpoint returns an array of Cook County agencies, each with name and url fields. The first three results are enriched with phone, email, address, and director fields where available, making it useful for building contact directories or routing inquiries to the correct agency. The search_property_tax endpoint accepts a pin parameter (Property Index Number, e.g. 17321100010000) and returns city, address, total_tax, and assessed_value for the matched parcel. Note that this endpoint is currently unavailable due to an upstream TLS certificate issue on the source site.
Court Cases and Code Violations
The search_court_cases endpoint accepts a required case_number string and an optional division code: 1 for Civil, 2 for Law, 3 for Chancery, and 4 for Domestic Relations. It returns an array of matching case objects, allowing you to narrow searches to a specific division of the Cook County court system. The search_code_violations endpoint takes a ticket_number and returns the Cook County DACRA violations portal URL alongside the submitted ticket number, directing you to the authoritative portal for full violation details.
Coverage and Limitations
All data reflects publicly available Cook County government records. The get_department_contacts endpoint enriches only the first three agency results with full contact details. Property tax lookups are blocked by an ongoing upstream TLS issue. Code violation results surface the portal URL rather than inline violation data, so full ticket details require a follow-up visit to the DACRA portal.
