Cloudmersive Validate

About Cloudmersive Validate

Cloudmersive Validate is a set of data validation APIs for verifying business-critical information, covering email addresses, phone numbers, street addresses, VAT numbers, domain names, names, and IP addresses. Email validation checks syntax, domain, and mailbox validity, and flags free webmail, disposable, and catch-all addresses. Phone validation parses and standardizes international numbers, returning type, country, and formatted representations. VAT validation checks EU VAT numbers against European Commission databases and returns associated business name and address. Domain validation retrieves WHOIS information, and IP address validation returns geolocation and related details.

The APIs are aimed at developers integrating identity and data-quality checks into signup flows, CRM systems, or data synchronization pipelines. Client libraries are available for .NET, Java, Node.js, Python, PHP, Ruby, Objective-C, and Drupal, along with Swagger/OpenAPI documentation and interactive try-it tools.

Deployment options include public cloud, dedicated managed infrastructure, private cloud or on-premises, PaaS (including Azure Kubernetes Service and Azure App Service), and government cloud regions. A free tier offers 600 API calls per month with no expiration.
