For agencies: US accessibility data and audits for your clients
We measured 11,902 US municipal and county websites and 133,165 business organisations with a website. Agencies use it to find clients who need help, show them evidence and sell the fix.
What the data looks like
Static JSON files on our CDN with an open CORS header — no key, no rate limit, nothing to install. One file per state.
- https://aifa.works/map/summary.json — totals and the state rankings
- https://aifa.works/map/m/NY.json — municipal sites of one state: pages, outcomes, dates, reasons
- https://aifa.works/map/c/NY.json — business sites of one state: axe-core violations by severity, date of the check
- /data — the full research dataset with its method and history
