About

APIVoid is a powerful suite of cybersecurity APIs that enables seamless threat detection, analysis, prevention, and data enrichment through simple JSON‑based HTTPS POST requests. It includes specialized APIs such as IP reputation (70+ scanning engines, detection of proxy, VPN, TOR, hosting, and IP geolocation), domain reputation (30+ engines, domain age detection and risky category identification), URL reputation (70+ security checks for phishing and suspicious URLs, providing detailed insights), email verify (detection of fake, temporary and suspicious emails, flagging misconfigured domains), phone validator (number validation and normalization with international/E164 formatting, carrier and line‑type identification, and fake or abusive number detection), and site trustworthiness (assigning trust scores to websites to identify fraudulent or insecure web shops).

About

ZelNum is a web-based verification and data-cleansing platform for businesses, sales teams, marketers, and developers. It helps users verify WhatsApp, Telegram, and phone numbers, check carrier and line-type information, and enrich contact records with country and phone data. Users can run individual checks, upload CSV or TXT files for bulk processing, or connect through the API for automated workflows. With more than 40 verification checks available, ZelNum helps teams clean contact lists, improve data quality, qualify leads, prepare outreach campaigns, and review potential risks. Free manual tools are available, while paid checks use transparent pay-as-you-go pricing with no subscription required. ZelNum provides verification signals, not identity proof, and should be used only with authorized data.
