ContactLint offers a hosted HTTP API and remote MCP server that validates email addresses and phone numbers. It checks syntax, DNS MX records, disposable domains, role addresses, and common typos for emails, and parses and formats phone numbers. The service provides a free tier of 100 checks per month and paid plans starting at $9 for 5,000 checks. It includes batch validation, widget integration for signup forms, and detailed usage reporting. Designed for developers and AI agents, ContactLint aims to improve data quality and reduce bounce rates.
