Melissa.com’s Open API Initiative makes a comprehensive suite of RESTful Cloud APIs available to developers worldwide. Built “for Developers, by Developers,” the program delivers scalable, production-ready endpoints for global address verification, email/phone validation, property data enrichment, name parsing, IP geolocation, and more—covering 250 countries.
Each API includes full OpenAPI (Swagger) specifications, detailed documentation, code samples, and flexible single-record or batch processing options. Developers simply create a free account to receive a license key with starter credits, then integrate instantly via simple HTTP calls.

By removing barriers to high-accuracy reference data, Melissa’s initiative accelerates innovation and helps businesses build cleaner, more reliable applications.
