}Reverse IP Append API FAQ
Common questions about our IP intelligence service
The API returns geolocation data (country, state, city), ISP information, risk indicators, and when matched, contact details like name, address, and email from our consumer database.
Identity match rates are moderate (10-25% depending on IP type) as many IPs are dynamic or shared. Geolocation data is highly reliable. Each response includes confidence indicators.
We detect VPN and proxy IPs and flag them in the response. Identity enrichment is typically not possible for anonymized IPs, but geo and risk data are still provided.
Reverse IP append costs 10 tokens per request. You are only charged for successful requests where identity data is found.
