About

TrustLookup is a hosted API and web dashboard for checking phone numbers, email addresses, IP addresses and domains. The API identifies each value and returns results for selected checks. Phone checks cover validity, format and line type; paid-plan lookups add the current carrier, number portability and live HLR status. Email checks assess syntax, mail servers, mailbox response, disposable and role addresses, and catch-all domains. IP results include location, network and ISP, hosting, VPN, proxy and Tor indicators, plus a free public spam-blocklist check. Domain lookups provide WHOIS and age information. Free tools check SPF and DMARC records and provide VIN, NPI and USDOT lookups. Users can check items in the browser, call the API or upload CSV files for bulk processing. Paid plans include Pro phone lookups and CSV uploads; Growth and Scale add webhooks, and Growth includes five team seats. The service supports developers and teams reviewing signups, contact data and risk.

About

UserCheck is a real-time email validation API that detects and blocks disposable, temporary, and suspicious email addresses and domains so tools can focus on genuine users and reduce fake sign-ups and abuse. It verifies whether an email or domain is valid, active, and trustworthy, checks domain reputation, identifies public email providers, relays, role accounts, and offers smart suggestions for common typos, syntax validation, and bulk processing of large lists. UserCheck continuously updates its disposable email database and enhanced validation rules, and it integrates seamlessly via a simple REST API with predictable JSON responses for efficient, low-latency verification workflows. It scales to handle high volumes of requests without performance degradation and offers organizational features like environment separation for development, staging, and production workflows. Additional capabilities include custom blocklists, webhooks, and integrations with tools.
