CallerAPI

CallerAPI is a Caller ID, robocall prevention and telecom spam protection platform that gives carriers, MVNOs, CPaaS and UCaaS providers, Voice AI platforms, SIP/VoIP operators, and mobile security vendors real-time phone intelligence to stop spam, reduce fraud, and increase revenue. Through a single scalable API, a self-hosted spam feed, white-label SDKs, and a SIP firewall, CallerAPI delivers: - Spam score, reputation, and complaint history - Business identity (name, location, industry) across 195 countries - Carrier data, number type, and optional HLR lookup - Live fraud and spam detection covering 30+ countries The spam database updates every 60 seconds with 15 days of rolling history, enabling zero-latency blocking at the switch or network edge. Average API response times are under 300 ms, and the infrastructure is built to handle hundreds of millions of lookups per day. Most customers use CallerAPI in two ways: to cut the cost of answering or processing spam calls, and to resell spam protection and caller intelligence as a branded value-added service that increases ARPU and reduces churn. White-label SDKs (Swift, Java/Kotlin, Flutter, React Native) and an Asterisk module let platforms keep their own brand in front of end users. Self-serve plans start at $25/month, with volume tiers scaling to tens of millions of monthly lookups. The Spam Database Feed, SDKs, and turnkey integrations are licensed directly to match each deployment. CallerAPI is a founder-led company based in Switzerland, with the main operating entity located in the US, focused on practical, high-accuracy telecom protection that sits quietly in the call path and helps operators, platforms, and apps keep networks clean and customers protected.
