Geocoding — entry 032 of 80
HackMyIP
HackMyIP is a fully free, keyless REST API covering IP geolocation, ISP/ASN lookup, VPN/proxy/datacenter detection, and an A–D privacy "cleanliness" score, plus email-breach checks (via the XposedOrNot database), DNS, WHOIS, and reverse-DNS lookups across ten endpoints. Its published OpenAPI 3.1 spec (served live at /.well-known/openapi.json) confirms every route returns JSON with an open Access-Control-Allow-Origin: * header; the unauthenticated tier is rate-limited to 100 requests per 60 seconds. No signup, API key, or credit card is required for any endpoint.
