GACS Scam-Check API
Check a website, phone number, crypto wallet, email or social handle against the GACS scam registry from your own app. Each request counts as one check. When you reach your monthly allowance, requests pause until next month or until you upgrade — you are never billed extra.
The free RSS feed, widget and browser-extension lookups on the developers page stay free.

How to use it
curl -H "Authorization: Bearer YOUR_KEY" \ "https://gacs.app/api/public/v1/check?q=example.com"
The response says whether the value is flagged and lists matching registry entries (name, category, severity, number of reports, dates, and a link to the public page). No reporter or victim details are ever returned. Errors: 401 bad key, 402 no active plan, 429 monthly allowance used.
