Stormwater Compliance API

The AUE Land Compliance Checker API provides free, structured access to stormwater regulatory data for 20 counties across South Carolina, Georgia, Florida, and North Carolina. Developers and researchers can query available states, counties, and health status without authentication.

POST /api/check

Generates a full stormwater compliance report for a specific county. This endpoint requires a valid Cloudflare Turnstile CAPTCHA token, so it cannot be called programmatically without browser-based verification.

Note: For programmatic access to regulatory data, use the county regulatory pages or the MCP server described below. The /api/check endpoint is designed for interactive use through the Compliance Checker on this website.

Rate Limit

10 requests per day.

Rate Limits

The public GET endpoints (/api/states, /api/states/{state}/counties, /health) have no strict rate limits, but please be respectful. The compliance report endpoint has a hard limit:

Endpoint Limit Auth Required
GET /api/states None No
GET /api/states/{state}/counties None No
GET /health None No
POST /api/check 10/day CAPTCHA token

Data Coverage

The API currently covers 20 coastal counties across four southeastern states. Each county record includes local ordinances, state permit requirements, BMP specifications, enforcement contacts, and fee schedules.

State Code Counties Count
South Carolina SC Beaufort, Berkeley, Charleston, Colleton, Dorchester, Georgetown, Horry, Jasper 8
Georgia GA Bryan, Camden, Chatham, Glynn, Liberty, McIntosh 6
Florida FL Duval, Nassau, St. Johns 3
North Carolina NC Brunswick, New Hanover, Pender 3

For detailed regulatory data by county, visit the county regulations pages.

MCP Server

For AI assistant integration, AUE Land provides a Model Context Protocol (MCP) server. The MCP server gives AI tools like Claude, ChatGPT, and other LLM-based assistants direct access to the stormwater regulatory database, enabling them to answer questions about permits, BMP requirements, and local ordinances with up-to-date data.

If you're building an AI-powered tool that needs stormwater compliance data, the MCP server is the recommended integration path. Contact us at info@aueland.com for access details.

Data Freshness

Regulatory data is updated through an automated monthly monitoring pipeline that runs on the 1st of each month. The pipeline checks for permit reissuances, fee changes, ordinance amendments, URL validity, and agency updates across all 20 counties. Changes are applied automatically and deployed without manual intervention.

This means the data you receive from the API reflects the most current regulatory landscape, typically no more than 30 days behind any published change. For a log of recent updates, see the regulatory changelog.

Attribution

This API is free to use. If you incorporate the data into a publication, application, or research project, we ask that you credit AUE Land as the data source. A simple attribution like the following is appreciated:
